B. PRASANNAThe growth performance of goats under different systems of rearing was studied for 13 weeks on thirty weaned local kids of 3-4 months of age and comparable body weights. Kids were randomly distributed into three groups with 10 animals in each group. Animals of T1 (Intensive system) group were fed with concentrate mixture and weighed quantity of ground nut hay, sesbania and ragi straw (ad lib). The animals in T2 (Semi intensive system) group were allowed for grazing for 6hours and in the evening provided with concentrate and roughages at the level of 50% of the requirements of T1 group. The animals in T3 (ExThesisItem Open Access A STUDY ON GROWTH PERFORMANCE OF KIDS UNDER DIFFERENT REARING SYSTEMS(KARNATAKA VETERINARY, ANIMAL AND FOISHERIE'S SCIENCES UNIVERSITY, BIDAR, 2019-08) SUMITRA B. MALLUR; M. C. SHIVAKUMARThe present study was conducted with the objective of assessing the growth performance of local kids of Hassan district, under the intensive and semi-intensive systems of rearing, by recording the morphometric measurements and the body weights fortnightly. Similarly, the trial also aimed to analyze the influence of rearing systems on blood biochemical parameters, to study the environmental variations using ambient temperature (ºC) and Relative humidity (RH %) to arrive at THI in the study area and to evaluate the GIT parasitic load in the experiemental kids. The obtained values were analyzed statistically. The results revealed that the mean values for body weights of the kids recorded were non-significant (P>0.05) between the groups. The overall mean of the ADG (g/d) were found to be 23.72 ± 1.92 in group I and 22.74 ± 1.58 in group II, which were statistically (P>0.05) non-significant. Morphometric measurements viz., body length, height at wither and chest girth of the experiemental animals remained statistically non-significant (P>0.05) during the study. The overall incidence of the GIT parasitic load in both the rearing groups did not vary statistically (P>0.05) between the two rearing groups. Blood picture of the animals, with respect to the parameters like RBC (106 μl), Hemoglobin (g/dl), PCV (%) were found to be non-significant (P>0.05). Correspondingly, the WBC (103 μl) values remained majoritively significant (P0.05) at majority of the experiemental duration. Over all mean value of THI recorded was 85.55 ± 0.86 and 84.77 ± 1.76 during the first half (0th - 12th week) and second half (13th - 25th week) of the experiemental period, for which the animals were exposed throughout the study. Above study concluded that, rearing systems didn’t have much effect on the growth performance of present non-descript local kids. The probable reason may be due to the genetic make-up of the animals, which differs from breed to breed and variation in the agro-climatic and geographical set up from region to region.ThesisItem Open Access A STUDY ON GROWTH PERFORMANCE OF NATIVE CHICKEN UNDER INTENSIVE AND SEMI-INTENSIVE SYSTEMS OF REARING(KARNATAKA VETERINARY, ANIMAL AND FOISHERIE'S SCIENCES UNIVERSITY, BIDAR, 2019-10) LAXMESH KATTIMANI; Dr. M. C. SHIVAKUMARThe present study was conducted on 200 native chicken were distributed among intensive and semi-intensive systems of rearing (100 birds per each system) from 9th to 20th weeks of age. To study the effect of growth performance of native chicken under intensive and semi-intensive systems of rearing was taken up in the Department of Livestock Farm Complex, Veterinary College, Hassan and Yediyuru village, Hassan. respectively. Different management systems had significant (P0.05) between the two systems of rearing. The BCR was higher in semi intensive system 1.69 compared to intensive system of rearing 1.56. The average SFRB was 11.42 g/b/d observed during 9th to 20th weeks of age. The study was concluded that native chicken can be reared under intensive and semi-intensive system of management successfully. However, semi intensive system of rearing native chicken was found to be more economical than the intensive system of rearing.ThesisItem Unknown A STUDY ON THE MANAGEMENT PRACTICES DURING TRANSITION PERIOD IN CROSSBRED DAIRY COWS(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR–585401, 2018-07) VENU, R.; Dr. Y. B. RAJESHWARI)The objective of this study was to document the existing management practices in crossbred dairy cows during transition period and to assess the effect of nutritional intervention in Transition cows. The existing management practices were recorded by means of personal interview using a structured schedule, with respondents selected using a multistage stratified sampling procedure. Most farmers rearing crossbred dairy cows reared high yielding crossbreds, unrecognised buffalo breeds, sheep, goat or poultry; thus revealing the suitability of crossbred dairy cows to their production system. The most common management practices were loose housing, artificial insemination, stall feeding, good care and feeding practices for calves, good health care practices and adequate milking techniques. Transition cow management was also better with respect to feeding. The results of a feeding mineral mixture for three weeks during transition period revealed that feeding mineral mixture can avoid post parturient complications. Efforts must be made to educate farmers regarding improved management practices like construction of proper feed mangers, scientific waste management and better management of crossbred cows during transition period.ThesisItem Unknown FACTORS AFFECTING THE LACTATION PERFORMANCE OF DEONI CATTLE(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2019-08) SUPRIYA G; PRASHANT G. WAGHMAREThe objective of this study was to document the lactation performance of Deoni cattle at the Livestock Research and Information Centre (Deoni), Hallikhed, a livestock research centre of Karnataka Veterinary Animal and Fisheries Sciences University, Bidar. The present study was conducted on 78 Deoni cows. This study was undertaken based on lactation performance data of Deoni cattle for the period July 2015 to June 2018. Period of calving was recorded as Period 1 (July 2015- June 2016), Period 2 (July 2016- June 2017) and Period 3 (July 2017- June 2018) Season of calving was recorded as summer (March to June), rainy (July to October) and winter (November to February). Cows were grouped based on age, parity, period of calving and season of calving to study the effect of each on lactation performance and milk composition. Results indicated that age group had significant effect on Lactation Milk Yield (LMY) and milk fat. Parity had significant effect on LMY, PY and fat. Season of calving had significant effect on LL. Period of calving had no effect on any of the traits. The overall mean values were estimated to be LMY 1297.99 ± 51.41 kg, PY 6.19 ± 0.147 kg, LL 291.68± 6.786 days, Persistency 207.68 ± 5.105, fat 4.80 ± 0.014%, SNF 8.48 ± 0.008%, protein 3.10 ± 0.005%, lactose 4.68 ± 0.005 % and salt 0.650 ± 0.001%. It was concluded that Deoni cattle are highly suited as a multi-purpose breed for Bidar district and there is potential for improvement in the performance of the breed by means of selective breeding techniques.ThesisItem Open Access MORPHOMETRIC CHARACTERISTICS OF DIFFERENT STRAINS OF DEONI CATTLE AND THEIR RELATION WITH MILK PRODUCTION(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2019-08) MALLIKARJUN HATTARAKIHAL; Dr. VIVEK M. PATILThe present study was conducted on 297 adult female Deoni cattle which were part of project “Field Performance Recording of Deoni cattle in Bidar District" and LRIC (Deoni), Hallikhed (B), Bidar. Out of 297 Deoni cows, 184 animals’ available performance records were compiled. Coat colour was found to be white, irregular spots and clear white in 16.50, 55.89 and 27.61 % cattle, respectively. The overall mean for ear length, horn length, distance between horn bases, face length, chest girth, height at withers, abdominal girth, body length, height at hip, tail length and body weight of Deoni cattle was found to be 24.09 ± 0.145 cm, 18.20 ± 0.443 cm, 14.66 ± 0.111 cm, 48.06 ± 0.202 cm, 160.78 ± 0.467 cm, 126.16 ± 0.338 cm, 166.42 ± 0.516 cm, 129.70 ± 0.405 cm, 129.12 ± 0.388 cm, 88.97 ± 0.415 cm and 286.17 ± 1.637 kg, respectively. The overall mean for LMY, PY, LL, milk fat and SNF in Deoni cattle was observed to be 1223.37 ± 36.728 kg, 6.05 ± 0.138 kg, 293.72 ± 4.540 days, 4.545 ± 0.0242% and 8.240 ± 0.0117%, respectively. The Wannera strain had higher height at withers, height at hip, tail length, milk fat and SNF. Balankya strain had higher horn length, face length, distance between horn bases, lactation milk yield and peak yield. Shevera strain had higher chest girth, abdominal girth, body length, body weight, ear length and longer lactation length. Saigaon village has higher lactation milk yield. The horn length was positively and significantly correlated with lactation milk yield and peak yield. The body length was positively and significantly correlated with lactation milk yield. The cows with wide chest had significantly higher lactation milk yield and peak yield than the cows with narrow chest in Deoni cattleThesisItem Open Access UDDER AND TEAT BIOMETRY AND ITS RELATION WITH MILK PRODUCTION IN DEONI CATTLE(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2019-08) HIREMATH BASAVARAJ; Dr. PRASHANT G. WAGHMAREThe present study was conducted on 256 Deoni cattle in 13 villages and LRIC (Deoni) of Bidar district, which were included in the project “Field Performance Recording of Deoni cattle in Bidar district” as part of Rashtriya Gokul Mission. The strain-wise and parity-wise biometry of udder, biometry of teat, different shapes of udder and teats, lactation milk yield and correlations were studied in present study. The overall mean of udder length, udder width and udder depth were found to be 41.476 ± 0.3570, 37.773 ± 0.4770 and 15.238 ± 0.1070 cm, respectively. The overall mean of fore teat length, rear teat length, fore teat diameter and rear teat diameter were found to be 3.968 ± 0.0790, 3.505 ± 0.0750, 2.029 ± 0.0130 and 1.930 ± 0.0120 cm, respectively. There was no significant effect of strain on any of udder and teat parameters. However, significant difference was observed in parity on udder and teat biometry. The overall frequencies of bowl, goaty, pendulous and round shapes udder were 49.61, 14.06, 33.20 and 3.12, per cent, respectively. Hence, bowl-shaped udder found to be predominantly. The overall frequencies of bottle, cylindrical, funnel and pear shapes udder were 15.62, 42.96, 32.81 and 8.60, per cent, respectively. Therefore, cylindrical shaped teat found predominantly. The overall mean of lactation milk yield found to be 1173 ± 33.868 kg. There was no significant effect of strain and parity on lactation milk yield. The correlation studies showed that all udder and teat measurements had significant and low to moderate correlation with LMY. These findings suggested that the udder and teat traits correlations should be an important criterion for selection of high yielding Deoni cattle
