Anand Agricultural University, Anand
Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur
AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

ThesisItem Open Access ECONOMIC RAISING OF GIR ( Bos indicus ) CALVES BY FEEDING MILK REPLACER(AAU, Anand, 2006) ODEDRA, MULRAJ DEVABHAI; RAVIKALA, K.An experiment of thirteen weeks duration was conducted on eighteen weaned Gir calves randomly divided into three groups of six each. The first group received whole milk feeding, while the second group received milk replacer feeding replacing 25 per cent of milk and the third group received milk replacer feeding replacing 50 per cent of whole milk. Milk replacer was more or less similar to milk in composition and could sustain tiie growth rate of weaned Gir calves as appeared from the acceptability. The results revealed non significant differences in average daily gains under three treatment groups though the periodical changes in body weight were linear in nature. Milk replacer fed groups recorded poor growth compared to whole milk fed group. Changes in biometry were also non significant due to treatment effect. Overall liquid feed consumption, concentrate intake, roughage intake, total DMI (g/day), per cent DMI and DMI per kg metabolic weight did not differ significantly among three treatment groups. Though the consumption pattern of DMI was at par in all the three treatment groups, body weight gain was poor in T-2 and T-3 due to negative growth recorded in the second week of the experiment. Feed efficiency was at par in all the three treatment groups and it was higher in T-1 followed by T-3 and T-2 indicating the superiority of natural milk to that of milk replacer. Overall difference in the cost of feeding/kg body weight gain was also non significant in three treatment groups. Cost of feeding/kg gain was the lowest in T-3 followed by T-1 and T-2.ThesisItem Open Access BREED CHARACTERISTICS AND MANAGEMENTAL PRACTICIES OF KATHIAWADI HORSES-A FIELD STUDY(AAU, Anand, 2002) Prajapati, R. B.; Belsare, V. P.The present investigation was carried out to study the important breed characteristics of Kathiawadi horses and traditional managemental practices followed by horse owners in Ahmedabad, Surendranagar and Bhavnagar districts of Gujarat state. In all 260 Kathiawadi horses were covered to study physical characteristics and biometry. Status of Kathiawadi horse ferms were surveyed through personal interview of 184 horse owners in three districts. Kathiawadi horses have small erect ears, which touch to each other. The forehead is concave have wide nostrils, with large prominent eyes, straight back with long curley tail. Generally horse owners keep horses for hobby and ceremonial purpose. Although they keep animal for carting purpose also. Majority of farmers were having primary education and they belongs to general category like, Rajput and Kathidarbar. Practice of feeding were concentrate, green fodder and dry fodder and also jaggery were fed by some owners. Majority of the horse owner keep the animal as a family member and take care accordingly. However there were some differences in feeding practices according to availability of resources and socio economic structure. Majority of owners exercised and groomed their horses daily. The average working hours were 2.76 hours / animal. Majority of farmer keep 1-2 horses. On an average herd size was 1.67. The average age of mare studied was 7.74 years and stallion was 8.55 years. The pre-dominant body colours of Kathiawadi horses were Chestnut 35.8 per cent. Bay 34.2 per cent. Grey 22.3 per cent. Skewbald 4,23 per cent. While other colours were below one per cent. Colour markings observed in Kathiawadi horses were Star 41.15 per cent, Star-Strip 7.31 per cent, Star-Strip-Snip 15.78 per cent, Stocking 6.15 per cent, Blaze 0.69 per cent. Black Knee 0.38 per cent and Whirl on forehead 2.69 per cent. The average length of forehead was 18.54 cms, the average length and width of ears was 13.12 and 7.2 cms, the length and width of face was 33.41 and 19.80. The body length was 147.60 cms., the length of neck, back and tail was 78.39, 76.22 and 42.52 respectively. The chest width was 33.40 cms., heart girth and belly girth was 166.15 and 171.81 cms respectively. The distance between knee to fetlock and height at knee was 25.55 and 43.07 cms respectively. The diameter of hoof was 42.34 cms. Distance between fetlock to coronet and height at hock was 11.36 and 55.16 cms respectively. The distance between croup to head of tail was 33.62 cms while height at wither and height at rump was 145.74 cms and 146.56 cms respectively. The averse body weight of horses calculated was ranging from 473.58 kg to 519.07 kg. Newborn foal was allowed to suckle colostrum freely. The growing foal was kept with mother and was having free access to suckle sufficient milk from the dam. The various reproductive characters studied were. Age at Puberty 1060 days, Age at First Service 1632 days, Age at First Foaling 1966 days. Gestation Period 335.2 days, Service Period 155.5 days and Foaling interval 490.4 days. The study of breed characters and traditional managemental practices of Kathiawadi horses under field revealed the feet that there is an urgent need to expand veterinary and extension services specially in rural area of Kathiawad for development of this breed. Secondly there is also need to educate the horse owners in respect of proper feeding and breeding of Kathiawadi horses and strengthening of Veterinary Aid Centers and Service Centers.ThesisItem Open Access STUDIES ON FEEDING OF DETOXIFIED CASTOR SEED CAKE (Ricinus communis) IN COMMERCIAL BROILERS(AAU, Anand, 2005) SHARMA, RAVINDER; KHANNA, KULDEEPFour hundred twenty straight run "Cobb" day-old commercial broiler chicks of same hatch procured from Charotar hatcheries, Pansora, Anand, were randomly assigned to three dietary treatments viz. Tl: control broiler ration, T2: 5% detoxified castor seed cake based broiler ration and T3: 10% detoxified castor seed cake based broiler ration. There were 140 chicks in each treatment having fourteen replications (10 chicks in each replication). The isocaloric and isonitrogenous experimental rations formulated for two phases of growth were: Broiler Starter (0-4 weeks) and Broiler Finisher (5-6 weeks). The Crude Protein and Metabolizable Energy content of the broiler rations was decided keeping in view the genetic growth attained by "Cobb" during last twelve years. The rations were fortified with adequate vitamin supplements and coccidiostats. The birds were reared in the cage system of housing during the entire experimental period. The average initial body weight of day old chicks of the three treatment groups i.e. T1, T2 and T3 were 44.30±0.249, 43.67±0.291 and 43.90±0.365g, respectively that finally reached to 1513.77±12.315, 1508.96±15.876 and 1497.64±14.663g, respectively in T1, T2 and T3 at the end of 6 weeks. In this respect the treatment groups did not differ (P<0.05) from each other. The respective average body weight gain at the end of 4th week for T1, T2 and T3 was 750.82±6.680, 770.94±8.442, and 704.99±7.864g, respectively, while overall 0-6 week average body weight gain was 1467.99±11.165, 1458.47117.348 and 1452.99±14.479g for treatments T1, T2 and T3, respectively. The total average feed consumption during 0-6 week in Tl, T2 and T3 groups were 2549.74+18.444, 2653.87±16.008 and 2570.45±20.983g, respectively. The intake of broilers in Tl and T3 groups was statistically (P<0.05) similar but both differed from T2 group. Similar was the trend for the overall (0-6 week) average feed conversion ratio (kg/ kg weight gain), which was 1.69±0.011, 1.76±0.020 and 1.72±0.017 in T1, T2 and T3, respectively. The average percent livabilty of broilers in Tl, T2 and T3 groups was 96.4, 96.4 and 98.5, respectively. The European performance efficiency index for treatment groups T1, T2 and T3 during starter phase was 209.81+4.178, 214.5713.422 and 211.63±4.304; and the same during finisher phase respectively was 213.50±2.781, 204.05±4.323 and 207.77±3.667. The dressing yields observed were 1.06±0.04, 0.98±0.03, and 0.99±0.04kg in T1, T2 and T3 groups, respectively. The organs weight in treatment groups Tl, T2 and T3 with respect to Liver (37.61±1.76, 39.71±1.22 and 37.73±1.89g), Gizzard (33.81±1.83, 31.48±0.90 and 28.60±1.25g), Heart (7.79±0.50, 8.25±0.16 and 7.08±0.25g), Spleen (2.81±0.37, 2.66±0.16 and 2.76±0.28g) and Kidney (11.35±1.34, 11.63±0.54 and 11.88±0.49g) were more or less similar. The results of this study indicated that inclusion of detoxified castor seed cake up to 10% level in the broiler ration has no any adverse effect on feed intake, body weight gain, feed conversion ratio, Livability, carcass characteristics and European performance efficiency index.ThesisItem Open Access EFFECT OF QUALITY FEED AND LITTER MATERIALS ON BROILER PERFORMANCE(AAU, Anand, 2005) SHARNAM, KUMAR SHAMBHU; Patel, Ashok M.A field bench mark survey was carried out to study the basic problems faced by the farmers on quality feeds, suitability of litter materials and optimum floor space required for broiler production in nearby villages embarrassing 20-25 km radius of Veterinary College, Anand, Gujarat state. The experiment was conducted on 887 straight run day old commercial broiler chicks (Cobb) obtained from M/S Venkey's hatcheries Pvt. Ltd., Anand and the growth trial was conducted in layer house, poultry unit of the Instructional Farm, Department of Livestock Production and Management, College of Veterinary science and Animal Husbandry, Anand Agricultural University, Anand (Gujarat) from 03-09-03 to 08-10-03. The experimental birds were randomly distributed in eight equal floor spaced cells (125 sq.ft/cell). The two litter materials viz Rice husk (L1) and wheat straw + saw dust (L2) in equal weight based proportion were spread uniformly with one inch thickness initially in all eight cells and fed two different rations Ri (BS-I: 24.18 % CP and 2999 Kcal/Kg ME with 124:1 energy: protein ratio and BF-I: 22.22 % CP and 3108 Kcal/Kg ME with 140:1 energy: protein ratio) and R2 (BS-II: 22.12 % CP, 2879 Kcal/Kg ME with 130:1 energy: protein ratio and BF-II: 19.87 % CP and 2941 Kcal/Kg ME with 148:1 energy: protein ratio) in order to form four combinations viz. L1R1, L1R2, L2R1 and L2R2 of litter materials and rations. Broiler starters were given upto 3rd week after that broiler finishers rations were given to birds along with broiler starter in ratio of 25:75, 50:50 and 75:25 for two days consecutively in 4th week and during 5th week birds were fed on solely broiler finishers upto 35th day.ThesisItem Open Access STUDIES OF ASSOCIATION BETWEEN MORPHOMETRIC CHARACTERISTICS OF UDDER AND TEATS AND INCIDENCES OF SUB-CLINICAL MASTITIS IN CROSSBRED COWS MAINTAINED ON DAIRY FARMS IN ANAND DISTRICT(AAU, Anand, 2014) PATEL, YOGESHKUMAR GULABBHAI; TRIVEDI, M. M.The present study was carried out in Anand District of Gujarat state on 200 lactating crossbred cows of different parities and at different stages of lactation from 13 different dairy farms. The objective was to study the biometry and different shape of udder and teats and their association with incidence of sub-clinical mastitis. Biometry of udder (length, width and depth) and teat (length and diameter), morphology of udder (trough/round/goaty/pendulous shape) and teat (cylindrical/funnel/bottle/pear), test day milk yield, distance between teat end to floor, body condition scores (1 to 5 scale), temperature humidity index in cow sheds, udder and leg hygiene scores (1 to 5 scale), ideal milking practices score (1 to 10 scale) etc. were studied. Milk samples were examined to detect subclinical mastitis through California mastitis test. The pH of milk samples as well as somatic cell counts/ml of milk were estimated using digital pH meter and Fossomatic minor cell counter. Data were analyzed according to methods suggested by Snedecor and Cochran (1994). The mean udder length, width and depth was 58.24 ± 0.68 cm, 65.45 ±"' • 0.70 cm and 23.06 ± 0.34 cm, respectively. The mean teat length for fore teats and rear teats was 6.07 ± 0.05 cm and 5.39 ± 0.05 cm, respectively. The mean teat diameter were 2.72 ± 0.02 cm for fore teats and 2.64 ± 0.02 cm for rear teats. Fore teats had higher length and diameter as compared to the rear teats. The differences observed in mean udder length, width and depth in different parities were statistically significant (P<0.05). The differences observed in fore teat length and rear teat length in different parities were statistically significant (P<0.05). The differences observed in mean fore and rear teat diameter in different parities were statistically non-significant. Udder length, width and depth showed declining trend with advancement of stage of lactation. The differences observed in mean udder length, width and depth in different stages of lactation were statistically significant (P<0.05). The differences observed in mean fore & rear teat length and fore & rear teat diameter in different stages of lactation were non-significant. Significant (P<0.01) and positive correlations were observed among the udder measurement traits viz., udder length and udder width (0.697), udder width and udder depth (0.685) and udder length and udder depth (0.526). Similarly, positive and significant (P<0.05) to highly significant associations of udder width and udder depth with average fore teat length, rear teat length, fore teat diameter, rear teat diameter, overall teat length and overall teat diameter were observed. However, udder length was positive and significantly (P<0.05) correlated only with teat diameter traits i.e., fore teat diameter, rear teat diameter and overall teat diameter. The correlations observed among various teat measurements viz., fore teat length, rear teat length, fore teat diameter and rear teat diameter were also positive and significant (P<0.05) to highly significant. The correlations between milk yield and various udder measurement traits viz., udder length (0.499), udder width (0.413) and udder depth (0.178) were found positive and significant (P<0.05) to highly significant (P<0.01). All the teat measurement traits showed non-significant correlation with milk yield except the fore teat diameter which had positive and significant (P<0.05) association with milk yield. Among regression coefficients for estimation of milk yield from udder length, width and depth, equation with all three udder measurement traits together had the maximum R- value (28.80%). However, due to lower R- these equations were of very little value for practical use to estimate milk yield with greater degree of accuracy. The regression of milk yield on udder length, udder width and udder depth indicated that each cm change in these measurements causes 0.262, 0.211 and 0.187 kg change in milk yield. The frequencies of trough (bowl), round, goaty and pendulous type udder were 56.5 %, 19.5 %, 7.5 % and 16.5 %, respectively. Similarly, the frequencies of cylindrical, funnel, bottle and pear shaped teats were 24.75 %, 48.63 %, 22.13 % and 4.5 %, respectively. The udder measurements in crossbred cows were lowest in goaty shaped udder and highest in pendulous udders. The differences observed in mean udder length, width and depth due to different shape of udder were statistically highly significant (P<0.01). The teat measurements in crossbred cows were lowest in pear shaped teats and highest in bottle shaped teats. The differences observed in mean teat length and teat diameter due to different shape of teats were statistically significant (P<0.01). Mean test day milk yield observed in crossbred cows was 10.11 ± 0.36 kg. It was 12.60 kg, 11.01 kg and 7.23 kg in early, mid and late lactation stages, respectively. Thus, mean test day milk yield showed decreasing trend with advancement in stage of lactation. The differences observed in mean test day milk yield between three different stages of lactation were highly significant (P<0.01). However, differences observed in mean test day milk yield due to parities were statistically nonsignificant. Mean test day milk yield (kg) observed was 10.34 ± 0.49, 10.63 ± 0.64, 6.68 ± 0.61 and 10.84 ± 1.04 in cows with trough, round, goaty and pendulous udder, respectively. The differences were statistically non-significant. Out of 200 cows 98 (49.00%) cows were found positive for sub clinical mastitis. In present study 184 (23 %) quarters from 200 cows (800 quarters) found positive for sub clinical mastitis. Thus, incidence of subclinical mastitis was 49 % on cow basis and 23 % on quarter basis. Among various shapes of udder, highest occurrence of subclinical mastitis was observed in cows having goaty udder (80.00 %) followed by pendulous (60.61 %), trough (46.02 %) and round (35.90 %) shape udder. The differences were statistically significant (P< 0.05). Among various shapes of teats, highest occurrence of subclinical mastitis was in cows having cylindrical teats (28.28 %) followed by funnel (22.11 %), bottle (22.03 %) and pear (8.33 %) shape teat. In cows all four types (trough/round/goaty/pendulous) of udder with combination of cylindrical shape teat had higher incidences of subclinical mastitis as compared to combination with other shaped teats. Highest incidences of subclinical mastitis (60 %) was observed in cows having goaty udder and cylindrical teats combination followed by pendulouscylindrical (50 %) combination. Round shape udder in combination with cylindrical, funnel and bottle shaped teats had less than 20 % incidences of subchnical mastitis. Similarly, trough-bottle combination also had less than 20 % reactors of subclinical mastitis. Therefore, cows of such combinations of udder and teats are preferred. Maximum number of positive subclinical mastitis cases were found in cows with medium udder length (48-68 cm) and udder width (55-75 cm) category (73 and 67 cows, respectively). Highest incidence (64.00 %) of subclinical mastitis was found in cows with udder depth greater than 28 cm. Higher incidences of subclinical mastitis were observed in cows having teats more than 5 cm length (24.20 %) as compared to cows having teats less than 5 cm length (20.66 %) teats. Mean teat length for affected teats was higher (5.76 ± 0.07 cm) as compared to healthy teats (5.64 ± 0.11 cm). Teats with more than 2.75 cm diameter had higher occurrence of subclinical mastitis (28.14) as compared to teats with less than 2.75 cm (17.92 %) diameter. Highest occurrence of subclinical mastitis was observed in right fore quarter (27.50 %) followed by left fore (23.00 %), right hind (21.50 %) and left hind (20.00 %) quarter. The occurrence of SCM was found more in fore quarters (25.25 %) than the hind quarters (20.75 %). Similarly, the prevalence of subclinical mastitis was higher in right quarters (24.5 %) than the left quarters (21.5 %). Maximum number of SCM cows had only single quarter infection (51.02 %) followed by two quarters (21.43 %), three quarters (16.33 %) and all four quarters (11.22 %). Highest occurrence of subclinical mastitis was observed in cows which were in late stage of lactation (55.41 %) followed by those in early (52.38 %) and mid (38.10%) stage of lactation. The incidences of subclinical mastitis were highest (56.41 %) in cows who had teat end to floor distance of 30-42 cm, followed by cows having distance between 42-54 cm (47.50 %) and distance between 54-66 cm (46.34 %). Highest incidence of subclinical mastitis was observed in under conditioned cows with BCS < 1 (66.66 %) & BCS 1-2 (58.14 %) followed by over conditioned cows (59.38 %) with BCS 3-4. Considerable less incidences were observed in moderate conditioned cows (42.97 %) with BCS 2-3. A linear increase in incidences of subclinical mastitis with increase in udder and leg hygiene score was observed. Higher incidences of subclinical mastitis were found in cows with UHS 4 (60.00 %), UHS 5 (60.00), LHS 4 (60.60 %) and LHS 5 (62.50 %). Similarly, lower incidences of subclinical mastitis were found in cows with UHS 1 (40.74 %), UHS 2 (51.06 %), LHS 1 (38.75 %), LHS 2 (51.11 %). Non-significantly positive correlation coefficient (r =0.16) was found between THI and incidences of subclinical mastitis on dairy fanns. A highly significant (P<0.01) and negative coefficient of correlation (r = -0.986) was observed between milking practices score and incidences of subclinical mastitis. Milk pH value showed elevation in SCM cows (6.96 ± 0.01) as compared to the healthy cows (6.75 ± 0.01). In SCM cows, pH was higher than 6.8 whereas, in healthy cows it was lower than 6.8. Mean SCC showed elevation in SCM cows (1466.12 ± 70.86 x 10 power 3) as compared to the healthy cows (123.67 ± 4.80 x 10 power 3). Among healthy cows, SCC were 91.00, 93.68, 105.08 and 117.38 thousands for trough, round, goaty and pendulous shaped udder, respectively. Therefore, goaty and pendulous udder had higher SCC than trough and round shape udders. Among SCM cows with different shape of udder, cows with goaty and pendulous udder had higher SCC i. e., 42 % and 19.95 % more than that of round and trough shaped udder, respectively. Similarly, SCM cows with bottle and cylindrical shaped teats had higher SCC than the SCM cows with funnel and pear shaped teats. Further, SCC were higher in right as compared to left quarters, and, hind quarters as compared to fore quarters. About 4.86 % to 47.65 % less milk yield was produced by SCM cows on different farms. Overall milk yield per day was 10.01 kg and 8.6 kg in healthy and SCM cows, respectively. Overall 13.79% less milk was produced by SCM cows than the healthy cows. Thus, among the various risk factors, pendulous and goaty udders, cylindrical teats, udder depth greater than 28 cm, teat length more than 5 cm, teat diameter more than 2.75 cm, early and late stages of lactation, fore and right side teats, teat end to floor distance < 42 cm, BCS less than 2 and more than 3 and udder & leg hygiene score between 2 to 5 were associated with increased incidences of subclinical mastitis in crossbred cows. Therefore, due care and precautions are necessary in such cows to reduce the occurrence of SCM on dairy farms. Dairy cows with pendulous and goaty shape udders should not be selected as such udder are more prone to subclinical mastitis. Economic effect and impact of subclinical mastitis was very high as SCM cows produced 13.79 % less milk than the healthy cows. Hygienic milking practices are very important to prevent or minimize incidences of subclinical mastitis on dairy farms.ThesisItem Open Access STUDY ON PRODUCTION PERFORMANCE AND GENETIC PARAMETERS OF SYNTHETIC LINE OF WHITE LEGHORN(AAU, Anand, 2006) BAROT, VASANTKUMAR NAVALJI; PATEL, ASHOK M.The present study was carried out to investigate the production performance, inheritance and association among various economic traits in a synthetic strain of White Leghorn for five successive generations under Central Poultry Research Station Project at Department of Poultry Science, Anand Agricultural University, Anand. Number of pullets from first to fifth generation utilized as experiraental materials were 413 (37 Sire family), 446 (30 Sire family), 441 (37 Sire family), 449 (40 Sire family) and 440 (39 Sire family).

The genetic correlations amongst body weight traits (BW20, BW40, BW56 and BW72) were positive and high in magnitude and in desired direction. The genetic correlations of BW20 with other growth traits (BW40, BW56 and BW72) ranged from 0.475 ± 0.226 to 0.924 ± 0.054. The genetic correlations of BW40 with BWse and BW72 were ranged from 0.491 ± 0.213 to 1.176 ± 0.117 where as the same between BW56 and BW72were ranged from 0.940 + 0.162 to 1.227 ± 0.115. The estimates of genetic correlations between body weight at 20 weeks of age and age at first egg were found to be low positive to negative side in all the generation except for the fourth generation. Contrary to this, positive and low genetic and phenotypic association was found between BW40 and age at first egg. The genetic correlations between body weight at 72 week and AFE were found to be positive, favourable and in desired direction. The genetic correlations of EN40 with various growth traits (BW20, BW40, BW56 and BW72) ranged from - 0.631 ± 0.244 to 0.230 ± 0.314 whereas genetic correlations of EN72 with various growth traits (BW20, BW40, BW56 and BW72) ranged little wider from -0.765 ± 0.429 to 0.278 ± 0.444. The genetic correlations of growth traits (BW20, BW40, BW56 and BW72) with egg weight traits (EW32, EW40, EW56 and EW72) were positive and moderate to high in magnitude. Negative genetic correlation of high magnitude was reported between age at first egg and egg production up to 40 weeks. In opposition to this, positive genetic and phenotypic association between age at sexual maturity and egg weight was reported. The genetic correlations between egg production (EN40, ENse and EN72) and egg weight traits (EW32, EW40, EW56 and EW72) were negative and high in magnitude in fifth generation. The phenotypic association of egg number with body weight and egg weight traits were negative and low in magnitude compared to genetic association.ThesisItem Open Access MICRO AND MACRO CLIMATE OF ANIMAL AND POULTRY HOUSES ON ORGANISED FARMS(AAU, Anand, 2005) NARWADE, BABAN MADHAVRAO; Patel, Ashok M.A study was carried out to find out the status of micro and macro climate of cattle and poultry houses on organized farms during (a) Summer: Hot dry (May and June 2003), (b) Monsoon season: Rainy-wet (August 2003), (c) Hot humid (September 2003) and (d) Mild Winter season: Cold dry (November 2003). For the purpose of study, following cattle and poultry farms of Anand Agricultural University, Anand; (i) Two sheds, cowshed and calf pen were selected from instructional Farm, Department of Livestock production and Management, College of Veterinary and Animal Husbandry, Anand (ii) cowshed at Livestock Research Station and (iii) cowshed at Holstein Friesian Bull Mother Farm and, (iv) at Central Poultry Research Station, three types of poultry houses namely (a) deep litter (b) cage house and (c) cage house with raised platform were selected. Meteorological observations were recorded at 7.30 am and 14.30 hours both inside and outside of cowshed, calf pen and poultry house by (a) Digital thermohygrometer (J411TH) for temperature & relative humidity (Plate XI), (b) digital anemometer (Lutron-AM4201) for wind velocity, (c) digital lux meter (Masteckms6610) for light intensity and (d) Yash High Volume Air Sampler (Yash Engineering, Vadodara) for dust concentration in the air of houses. The VIIVAS was placed in the center of animal and poiiHry houses and run for 3 hrs from 10.00 to 13.00 hrs. The average the dust concentration in the animal and poultry shed was calculated by difference of final weight and initial weight of filter paper on microbalance. The filter papers used were of Glass Microfibre Filters GF/A Cat No. 1820 866 Whatman International Ltd., England. The filter papers were packed in individual polypropylene bags. The sterilized bags were opened only at the site where it was directly placed in position in YHVAS machine with the help of sterilized forceps and run for three hours in animal and poultry sheds at 10:00 hours to 13:00 hours. The filter paper were removed and filled in the same polypropylene bags and weighed in the laboratory for difference between final and initial weights. These filter papers were used for total bacterial and fungal colony i. e. microbial colony count (c/w/plate). Mean inside cow shed temperature during hottest period of the day i.e at 2.30 pm during different seasons irrespective of farms was 38.92 ± 0.26, 28.76 ± 0.42, 33.27 ± 0.18 and 32.23 ± 0.34 °C whereas outside the cow shed was 42.49 ± 0.40, 29.76 ± 0.47, 37.28 ± 0.39 and 36.76 ± 0.68 °C during hot dry (S1), rainy-wet (S2), hot humid (S3) and mild winter (S4) season, respectively. The mean difference (outside minus inside the cowshed) was 3.57, 0.75, 4.01 and 4.55°C during S1, S2, S3 and S4 season, respectively. Highest and lowest temperatures were recorded during hot dry and rainy wet season, respectively. Less difference (outside minus inside the cowshed) was observed during rainy wet. It may be due to rain and high humidity during this season, however, more difference was recorded during hot dry, hot humid and mild winter seasons. Season conflict was significant, it is bound too be. During hot dry season the inside temperature was lower by 3.57 °C than the outside intense temperature 42.49 °C, however, inside temperature of 38.92°C was also higher and or uncomfortable to cows.ThesisItem Open Access FACTORS INFLUENCING ADOPTION OF SOME IMPROVED ANIMAL HUSBANDRY PRACTICES OF DAIRYING IN ANAND AND VADODARA DISTRICTS OF GUJARAT STATE(AAU, Anand, 2002) GOUR, ANIL KUMAR; PATEL, ASHOK M.The dairy farming plays a pivotal role in the economy of our country. It helps in augmenting food supply, generating employment and raising nutritional level. The major advantage of dairy farming is its minimum land dependency and resource flexibility. It is a major source of income to major segment to rural betterment in small and marginal farmers, at the same time it is also characterized with risk and uncertainty. It is therefore, use of modem inputs and adoption of new technology of animal husbandry are undoubtedly more important in increasing dairy farm productivity. There is a considerable gap between present animal husbandry practices of the dairy farmers and available scientific animal husbandry development so far. Out of these, which technology are known and adopted by its real users of different classes is a matter of question. Hence, to analyze the existing extent of knowledge and adoption of the dairy farmers, the present study on "FACTORS INFLUENCING ADOPTION OF SOME IMPROVED ANIMAL HUSBANDRY PRACTICES OF DAIRYING IN ANAND AND VADODARA DISTRICTS OF GUJARAT STATE" was undertaken. OBJECTIVES: 1. To study the profile of dairy farmers of Anand and Vadodara districts of Gujarat. 2. To study the extent of knowledge of dairy farmers regarding improved practices of animal husbandry. 3 To study the extent of adoption of improved practices of animal husbandry by dairy farmers. 4. To find out relationship between extent of knowledge of dairy farmers regarding animal husbandry practices and dairy farmers profile. 5. To find out relationship between extent of adoption of improved animal husbandry practices and profile of dairy farmers. 6. To know the problems faced by dairy farmers in adoption of modem practices of animal husbandry, and 7 To seek suggestions to overcome problems/limitations of dairy farmers in adoption of modem practices of animal husbandry. The present study was conducted in randomly selected sixteen villages of Anand and Vadodara districts. A sample of 172 dairy farmers having milch animals was selected for the study. The data were collected with the help of "interview schedule" by conducting personal interview. For the measurement of independent and dependent variables, appropriate scales developed and adopted by other research workers were used with due modifications. The statistical tools used for the analysis of data were percentage. mean, standard deviation, correlation coefficient, stepwise regression and path analysis. The important findings of the study are summarized as under; 1. Majority of the dairy farmers (76.74 per cent) had middle age, secondary and higher secondary level of education (58.72 per cent), higher caste (61.63 per cent), organizational participation in dairy co-operative society (57.56 per cent), medium level of mass media exposure (43.60 per cent), medium to high level of extension contact (77.33 per cent), marginal, small and medium dairy farmers had less than four ha. of land holding (72.09 per cent) and low to medium level of herd size (67.50 per cent). 2. The average parity of dairy animals of dairy farmers was observed 3.67 ± 0.08 while, the average age at first calving in indigenous cows, crossbred cows and buffaloes was 47 months, 34 months and 46 months, respectively. Whereas average peak milk yield was 9.03 ± 0.39 litres and average annual expenditure for medical treatment was Rs. 254.30 per animal. The average number of earner, dependent and total members of family was 2.0, 4.0 and 6.0 respectively. Great majority of dairy farmers (94.77 per cent) were dependent on crop farming, dairying and other occupation, and majority (87.57 per cent) of them had increased their total income upto 10 to 25 per cent due to adoption of dairy farming. 3. Majority of the dairy farmers (69.18 per cent) had medium to high level of economic motivation, medium to high level of scientific orientation (79.07 per cent), medium to high level of planning orientation (62.79 per cent), medium to high level of production orientation (70.93 per cent), high level of market orientation (53.49 per cent), medium to high level of competition orientation (77.91 per cent), medium to high level of supervision on dairy production (74.42 per cent) and low level of orientation towards development of skill in farm workers (55.23 per cent). 4. Majority of the dairy farmers had medium to high level of knowledge (68.60 per cent) and adoption (81.98 per cent) regarding improved animal husbandry practices. 5. Continuous rate of adoption regarding improved animal husbandry practices viz. reproductive practices was observed in between 72.10 to 91.86 per cent, nutritional practices in between 59.88 to 95.93 per cent, managemental practices between 52.91 to 98.84 per cent, disease control practices between 32.56 to 97.09 per cent and marketing practices between 32.56 to 100.00 per cent by dairy farmers. 6. Great majority of the dairy farmers of Anand district had perception of majority of the activities carried out by Amul Dairy. 7. The variables namely extension contact, animal possession, economic motivation, scientific orientation, planning orientation, production orientation, market orientation, management orientation, competition orientation, orientation towards development of skill in farm workers, supervision on dairy production and adoption of animal husbandry practices had positive significant relationship with the knowledge of dairy farmers, while land holding and total number of occupation had negative and significant correlationship with their knowledge regarding animal husbandry practices 8. The variables namely extension contact, animal possession, economic motivation, scientific orientation, planning orientation, production orientation, market orientation, management orientation, competition orientation, orientation towards development of skill in farm workers, supervision on dairy production and knowledge were positively and significantly correlated with adoption, while land holding and total number of occupation were negatively and significantly correlated with their adoption regarding improved practices of animal husbandry. 9. The variables namely management orientation, milk yield, competition orientation, land holding, market orientation, extension contact and total number of milch animals jointly contributed 67.24 per cent of total variation in the knowledge of improved animal husbandry practices of dairying. 10. Four variables viz. knowledge, production orientation, orientation towards development of skill in farm workers and total number of animal together contributed 63.13 per cent of total variation in the adoption of improved animal husbandry practices of dairying. 11. Variables viz. market orientation, planning orientation, production orientation, competition orientation, extension contact, total animal possession, scientific orientation and orientation towards development of skill in farm workers exhibited positive direct effect, whereas management orientation had maximum total indirect effect and substantial indirect effect on knowledge regarding improved animal husbandry practices of dairying. 12. Variables namely managemental practices, nutritional practices, disease control practices, marketing practices, reproductive practices, planning orientation, market orientation, production orientation, orientation towards development of skill in farm workers, competition orientation and economic motivation, exhibited positive direct effect, while knowledge had maximum positive total indirect effect and management practices had highest substantial indirect effect on adoption regarding improved animal husbandry practices of dairying. 13. High cost of byre construction, lack of knowledge of recommended managemental practices, unavailability of reasonable and quality green fodder round the year, unavailability of comfortable and stress-free housing during summer season, lack of knowledge of viability of cattle/buffalo, difficulty to store milk during summer season and timely vaccination against diseases in the animals were the major problems faced by dairy farmers in adoption of improved animal husbandry practices. 14. Arrangement of regular visit of veterinary doctor and extension specialist, cooperative society should have the facility of preservation of vaccines and semen, atleast five members of a dairy co-operative society should be trained to solve the problems of animal husbandry, regular training should be provided to farmers to improve their knowledge for better adoption and loan/subsidy facilities should be made available for construction of cattle shed and purchase of dairy animals were the important suggestions given by the dairy farmers to improve level of adoption of modem practices of animal husbandry.ThesisItem Open Access COMPARATIVE PERFORMANCE OF SHADER AND NON-SHADER INDIGENOUS SHEEP UNDER MIDDLE GUJARAT AGRO CLIMATIC CONDITION DURING SUMMER SEASON(AAU, Anand, 2007) SINGH, DEEP NARAYAN; Wadhwani, K. N.The present experiment was conducted to compare the performance of shader and non-shader indigenous sheep under middle Gujarat agro climatic condition during intense summer season in the month of May-June at Instructional farm, Department of Livestock Production and Management, College of Veterinary Science and Animal Husbandry, Anand Agricultural University, Anand, Gujarat. This experiment was conducted on 20 adult female farms bom, unshorn, Marwari and Patanwadi sheep of Instructional farm. Veterinary College, Anand. The experimental animals were randomly divided in to four treatment groups on the basis of body weight each of five animals and housed under covered area viz. T1: Asbestos sheet roofed house, T2: Agro-net, T3: walled open yard under the trees shade and T4 : under open sky (expose to sun). The experimental animals were maintained on ICAR Feeding Standard (1998). The experimental animals at the end of the experiment attained 29.53 ± 0.28, 28.10 ± 0.21, 27.80 ± 0.27 and 27.62 ± 0.19 kg body weights with total gain of 1.65, d.90, 1,64 and 1.14 kg under T1, T2, T3 and T4, respectively. The shader animals grew to the tune of 5.92, 3.30 and 6.26 % under T1, T2, T3, respectively as compared to their initial body weight, where as non-shader sheep (T4) grew to the tune of 4.3 % in relation to their initial body weight. There was no significant mfluence of treatments, period and interaction of T X P on body weight of experimental animals. The experimental animals under T1 (750.25 ± 08.29) and T4 (722.58 ± 09.57) consumed daily dry matter intake (g) at par but had little higher in T2 (754.52 ± 13.67) and T3 (815.02 ± 12.92), differed significantly (P<0.05) from T1, T2 & T3. The animals under tree (T3) consumed 8.6, 8.0 and 12.79 % more dry matter as compared to the animals under T1, T2 and T4. The daily dry matter intake irrespective of treatments during different experimental periods differed significantly (P<0.05). The percent dry matter intake was 2.54 ± 0.04, 2.73 ± 0.04,2.94 ± 0.04 and 2.63 ± 0.04 in T1, T2, T3 and T4, respectively differed significantly (P<0.05) with treatment while period and its interaction effect with treatment were non-significant. The dry matter intake (g) per metabolic body weight was 59.24 ± 0.86, 62.48 ± 0.97, 67.29 ± 0.91 and 60.13 ± 0.77 in T1, T2, T3 and T4, respectively differed significantly (P<0.05) by the treatments only.
