    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2019-07) Dar, Aashaq Hussain; Sanjay Kumar
    The present study was conducted on Badri cattle and its three colour variants viz., grey, brown and black from Uttarakhand state of India. Efforts were made for phenotypic and genotypic characterization of Badri cattle. For genetic characterization, microsatellite (SSR) and gene based markers were utilized to assess the general and functional genetic diversity in Badri cattle. Sampling was done from both Kumaon and Garhwal divisions of Uttarakhand, covering five hilly districts from each divisions. For genetic characterization, a total of 96 blood samples collected; 90 samples from the breeding tract (9 samples each from the 10 districts) and 3 samples each from University Dairy Farm, GBPUAT, Pantnagar and State Breeding Farm, Champawat . Phenotypic characterization of Badri cattle indiacted that it is a small sized cattle with an average adult body weight of about 200-250 kg. The body is compact and cylindrical with tight skin. The muzzle, horn, eyelids, switch of tail and hooves are mostly black in colour. Udder is small sized and trough (bowl) type. The fore and hind quarters of udder were small and medium sized respectively. The teat shape was cylindrical (70 and 78 %) and funnel type (30 and 32%) in Kumaon and Garhwal respectively. Data analysis revealed that breeding tract regions had no effect while as sex and age has significant effect on morphometric traits of Badri cattle. Badri cattle produce about 1.61 ±0.02 kg milk per day of lactation. The average lactation length, dry period, age of puberty, age at first calving, service period and calving interval were found to be 323.10 ±2.71, 82.20 ±0.99 days, 3.38 ±0.05 years and 4.38 ±0.05 years and 5.12 ±0.09 and 14.05 ±0.09 months respectively. The milk constituents viz. fat, protein, lactose, SNF and total solid percentage was higher than exotic cattle and some Indigenous breeds. The present study revealed that the mineral composition of Badri cattle milk is comparable with other cattle breeds. Ca, Mg, P, and Na content increased significantly in the third stage of lactation while potassium showed a reverse trend. The average serum glucose, total protein, triglycerides, cholesterol, creatinine and urea were found to differ significantly in summer and winter seasons. Using light microscopy, it was revealed that the hair shaft and medullary diameter at medial region and both regions of body i.e. dorsal and ventral, differed significantly within colour variants of Badri cattle, i.e. Grey, black and brown variants. At both dorsal region and ventral region within the colour variant groups, there was a significant difference between cortical thickness of hair shaft at proximal, medial and distal part. Scanning electron microscopy (SEM) revealed that the medullary diameter was significantly higher in medial region of hair shaft as compared to proximal and distal part in all the colour variants at both dorsal and ventral regions of the body. The genotypic characterization revealed that there was ample of genetic diversity in all the colour variants. Bottle neck analysis revealed that Badri cattle and its colour variants are under bottleneck. Structure analysis revealed that all the three colour variants of Badri cattle are actually single breed. Further it showed Badri cattle is a distinct breed as revealed by structure analysis with Red sindhi, Sahiwal, Jersey and Holstein Fresian. Individual assignment using GENECLASS software revealed that the individuals in three colour variants were assigned to all the 3 colour groups while a few individuals were assigned to other breeds at a negligible probability. The polymorphism at kappa-casein, beta-casein, alphalactalbumen, beta-globulin, butyrophilin, growth hormone and prolactin were in close range with other Indigenous cattle breeds.

    Study on existing dairy animal husbandry practices in U.S. Nagar district of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-01) Yadav, Shikha; Anil Kumar
    Present study was carried on five different clusters involving 180 farmers from different five clusters, 36 farmers of each cluster were selected in U .S. Nagar district of Uttarakhand from January 2017 to June 2017 with the objective of studying socioeconomic profile, management practices, constraints etc. Maximum numbers of farmers of selected area were found socio-economically sound as land holdings were ranges from medium to large with them. The average number of cattle in the study area was 3.51±0.11 (ranges from 2.91±0.17 to 4.55±0.28) whereas the buffalo were 2.28±0.13 (ranges from 1.44±0.44 to 3.38±0.45) with average number of 5.79±0.24 total per household. Majority of the farmers had pucca house (73.89 percent), good sanitation (86.67 percent) and ventilation (85 percent), semi intensive type (76.67 percent) type of housing. Regarding existing feeding practices, most the farmers were aware about the importance of green fodder feeding, concentrate feeding, inclusion of mineral mixture and salt in feed and colostrum feeding. Farmers of study area has adopted artificial insemination in cattle (98.33 percent ), where as in buffalo 100 percent farmers were adopted naural insemination. They were aware about the symptoms of heat detection as well as insemination (93.33 percent) at right time i.e. in between 12-18 hours after onset of heat. The overall data revealed that majority of farmers i.e. 86.67 per cent followed vaccination schedule in their animals. Deworming, debudding in calf, navel calf treatment, measures to control ecto-parasites were the routine practices adopted by the majority of the farmers in selected area. Women were participating actively in all managemental practices including feeding, insemination, milking, sale of the animal etc. than the men. There were several constraints were also reported like unavailability of pedigreed buffalo bulls for natural insemination, lack of knowledge of contagious diseases and their preventive measures etc. Based on above it can be concluded that majority of dairy farmers were found to have high level of awareness regarding housing, feeding, health care and breeding management. It was also concluded that role of women in most of the animal husbandry practices were predominant in the survey area. There were certain aspects where they followed management practices properly to certain extent but most of the feeding and breeding practices need to be improved in surveyed area. To overcome the constraints of various management practices, awareness and motivation camps should be organized.

    Studies on comparative efficacy of herbal methionine vis-à-vis synthetic dl-methionine supplementation on the performance of commercial broiler chicks during winter and summer season
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-08) Nanda, Subhankar; Tiwari, D.P.
    Two feeding trials viz., during winter and summer seasons were conducted to discern the comparative effect of dietary supplementation of herbal methionine vis-à-vis synthetic DL-methionine on growth performance, nutrient utilization, carcass characteristics and serum biochemical parameters and economics (feed cost/ kg body weight gain) in commercial broiler chickens. In both the seasons 180, day-old broiler chicks were divided randomly into 6 treatment groups with 3 replicates each that is 10 broiler chicks per replicate. The broiler chicks of treatment group T1 (control) were fed basal diet (starter and finisher diet), whereas in treatment groups T2, T3, T4 and T5 basal diets were supplemented with 0.2 % DL-methionine, 0.15 % DL-methionine + 0.05 % herbal methionine, 0.1 % DL-methionine + 0.1 % herbal methionine, 0.05% DL-methionine + 0.15 % herbal methionine and 0.2 % herbal methionine by replacing the DL-methionine at 0,25, 50, 75 and 100 per cent levels respectively. In both winter and summer seasons, the feeding trial lasted for viz., 0-21 days (starter phase) and 21-42 days (finisher phase). A metabolism trial was conducted during 6th week of feeding trial. Blood samples were collected on 42nd day of feeding trial for the study of serum biochemical parameters. At the end of feeding trial on 42nd day, 3 chicks from each replicates were sacrificed for the study of carcass characteristics. The growth performance parameters obtained during winter and summer seasons were pooled and average values were recorded. During starter phase, there was significant difference in body weight gain amongst the different treatment groups of broiler chicks. The overall average body weight gain was 618.45, 637.73, 639.60, 649.40, 641.35 and 653.88 g, respectively, in broiler chicks of T1, T2, T3, T4 T5 and T6. The highest body weight gain was in treatment T6 and lowest in treatment T1. The feed intake, performance index, protein efficiency ratio and production efficiency factor did not differ significantly among different groups. The feed conversion ratio was significantly better in treatment T6 than other treatment groups. During 21-42 days (finisher phase) the overall average pooled body weight gains in broiler chicks were 1284.90, 1325.51, 1399.52, 1326.82, 1357.50 and 1354.42 g, respectively, in the treatment groups T1,T2, T3, T4 T5 and T6 and differed significantly amongst the groups. Body weight gain was maximum in treatment T1. The feed intake was also significantly higher in treatment T3, however, feed conversion ratio, performance index, protein efficiency ratio and production efficiency factor in broiler chicks of various groups were statistically similar. During the entire feeding trial (0-42 days) the overall cumulative average pooled values showed significant difference (0.01) in weight gain and feed intake amongst the different treatment groups of broiler chicks. The average body weight gain was 1903.29, 1963.24, 2039.11, 1976.22, 1998.85 ad 2009.75 g in broiler chicks of treatment groups T1,T2, T3, T4 T5 and T6, respectively. The feed intake was highest in treatment group T3 and lowest in treatment T1, whereas feed intake was statistically similar in treatment T2, T3, T4, T5 and T6. There was no significant difference in feed conversion ratio, performance index, protein efficiency ratio and production efficiency factor among the different treatment groups. There was significant difference in nutrient utilization in dry matter, crude protein, ether extract, and gross energy amongst the different the treatment groups. The nutrient utilization was highest in treatment T5 and T6 and lowest in treatment T1 and T2. The various carcass traits in broilers were not affected due to either sources of methionine supplementation but dressing percentage was significantly highest in treatment T6 than treatment T1. There was significant difference in dry matter, crude protein, ether extract content in breast and thigh muscles of broiler chicks. The serum biochemical parameters showed significant reduction in cholesterol and triglycerides contents in treatments T5 and T6 as compared to other treatment groups. The serum glucose, total protein, albumin and globulin concentration were significantly higher in broiler chicks of herbal supplemented groups. The activities of SGOT, SGPT and ALP differed significantly amongst the treatment groups. The SGPT and SGOT values were significantly higher in treatment groups T1 without any methionine supplementation than the broiler chicks fed diet supplemented with herbal methionine as well as synthetic DL-methionine. The feed cost/ kg weight gain differed significantly during starter and finisher phase of feeding trial and the overall pooled values of feed cost per kg body weight gain were considerably higher in treatment groups and supplemented with herbal and synthetic DL-methionine than broiler chicks of control groups. It was concluded that supplementation of herbal methionine in the diet of starter and finisher broiler chicks improved the growth performance and nutrient utilization coupled with reduction in serum cholesterol and triglyceride without affecting the carcass traits but the feed cost per kg weight gain was increased due to supplementation of herbal as well as synthetic DL-methionine

    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2017-06) Khadda, Balbir Singh; Singh, Brijesh
    The present study was conducted in two parts, in first part relevant observations pertaining to goat husbandry practices followed by 645 goat keepers of district Udham Singh Nagar and Nainital were collected by using interview schedule, interview guide and direct observation methods whereas, second part comprised of a study on various performance traits of Pantja goats recorded on the basis of progeny data. The data of both the parts, generated under ICAR sponsored AICRP on goats (Pantja field Unit) located in the department of livestock production management, G. B. Pant University of Agriculture and Technology, Pantnagar (Uttarakhand). Results of the study showed that majority (90.39 %) of goat rearers belonged to Hindu religion, 55.97% of respondents lived in nuclear family with 53.64 % having a family size of more than 5 members. Overall literacy rate was 64.96 per cent. Majority of the farmers rearing Pantja goats were from Scheduled castes (43.88%) and 82.95% belonged to the middle age group. Majority of the goat keepers (47.91%) followed animal husbandry as a primary profession and 73.80% were landless peasants and 71.97% households earned a total income of more than Rs.50, 000 per annum. Women’s play role in parturition (73.95%), followed by cleaning of animal shed (61.40%), care of sick animal (56.43%), stall feeding after grazing (54.11%), care of young stock (52.40 %), spraying/ dusting (54.26%) and grazing of animals (47.44%). Majority of goat keepers (59.69%) maintained the flock within a shed near to own residences (79.84%) at night with incomplete boundary wall (43.88%) and 62.79% had kachcha floor in goat sheds and (84.65%) used temporary type of roof. Most of the goat rearers (78.29 %) did not have manger and 65.43% had poor sanitation in the sheds. Majority of goat keepers (65.58%) adopted semi stall feeding system. Grazing was done mostly on community land (95.97%) . The maximum proportion of goat rearers fed 100-200g concentrate/goat/ day. Majority of goat keepers (89.15%) did not provide mineral mixture. Majority of goat keepers (94.42%) practised heat detection. Pregnancy diagnosis was followed by 90.70% of the goat keepers by own judgment (92.825). Majority of goat rearers practiced deworming (70.39%), vaccination (55.81%) and control of ecto-parasites (61.24%). Majority of goat keepers (67.91%) were not aware of the care of navel cord of new born kids and 52.25% were not following the practice of castration of the male kids. Most of the goat rearers (92.71%) sold the female goats at own home through middle men (68.22%) based on physical appearance (46.82%) round the year for cash needs (68.84%). The study revealed that 87.59% investment was made on cost of goats and the overall variable cost contributed 77.89% to the gross cost. The net income over gross cost per household was observed to be Rs. 7267.89, 18133.40, 31243.90 and 56028.00 in small, medium, semi-large and large flocks, respectively. The overall least-squares mean for body weight at birth and at 3, 6, 9 and 12 months of age were found to be 1.89±0.02, 9.49±0.20, 13.09±0.18, 16.38±0.19 and 18.84±0.22 kg, respectively. The overall least squares means were measured at birth, 3, 6, 9 and 12 months age for the morphometric traits viz. body height (28.55±0.11, 47.26±0.26, 52.23±0.32, 57.33±0.38 and 60.21±0.27 cm.), body length (26.90±0.13, 44.08±0.25, 48.05±0.15, 51.66±0.25 and 54.70±0.25 cm.), chest girth (29.11±0.15, 49.02±0.23, 53.45±0.32, 57.76±0.26 and 61.06±0.19 cm.), paunch girth (30.55±0.15, 51.83±0.29, 56.34±0.25, 60.81±0.33 and 62.98±0.25 cm.), ear length (9.55±0.09, 15.16±0.06, 16.28±0.06, 16.88±0.27 and 17.66±0.07 cm.) and ear width (4.57±0.06, 6.09±0.10, 6.72±0.08, 7.18±0.08 and 7.83±0.07 cm.). The overall least squares mean for horn length at 3, 6, 9 and 12 months of age were 2.12±0.07, 4.32±0.15, 5.93±0.18 and 6.46±0.18 cm, respectively. The overall least squares means for absolute growth rate, relative growth rate, instantaneous relative growth rate and Kleiber ratio were found to be 84.21±2.07, 39.93±0.77, 35.77±0.77 and 28.16±1.56g/ day; 3.98±0.08, 0.37±0.02, 0.24±0.01 and 0.16±0.01 kg/ kg; 1.75±0.02, 0.35±0.01, 0.24±0.01 and 0.17±0.01 per cent/ day and 15.29±0.16, 5.50±0.15, 4.24±0.09 and 3.53±0.37g between 0-3, 3-6, 6-9 and 9-12 months of age respectively. Based on results of present study it was concluded that the goat keepers of the region were not fully aware about improved goat husbandry practices. Pantja breed of goat has an immense production potential. The maximum potential has not been realized due to subsistence type of production system adopted by the goat keepers. It can be achieved by following improved husbandry practices, which will not only improve the productive and reproductive performance of the goats but also improve the socio-economic conditions of the goat rearers.

    Studies on feeding green berseem (Trifolium alexandrinum) on growth performance and carcass traits in pigs raised on kitchen waste based diet
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2010-08) Ravindra Kumar; Ashok Kumar
    A study was conducted to evaluate the effect of different levels of green berseem, kitchen waste and concentrate feeding on growth and carcass traits in growing and finishing pigs. The experiment was conducted in two phases using 24 LWY piglets of about 3 to 3.5 months age. During phase I, the performance of growing piglets was studied for 2 months. The details of feeding regimens in different groups were as follow, group I: 10% green berseem + 90% concentrate only, Gr. II: 10% green berseem + 25% kitchen waste + 65% concentrate, Gr. III: 10% green berseem + 50% kitchen waste + 40% concentrate and group IV: 10% green berseem + 75% kitchen waste + 15% concentrate. During phase II, the performance of finisher pigs was studied for 2 months. Pigs were divided again into 4 groups. Distributions of feed in different such groups have been presented as follow, group I: 10% green berseem + 50% kitchen waste + 40% concentrate, Gr. II: 15% green berseem + 50% kitchen waste + 35% concentrate, Gr. III: 20% green berseem + 50% kitchen waste + 30% concentrate and group IV: 25% green berseem + 50% kitchen waste + 25% concentrate. The ad libitum feeding would be done during both phases. During phase I, there was no significant difference between different treatment groups with respect to overall DM intake, body weight gain and FCR. However, better performance was observed for group IV. In conclusion, substitution of concentrate for different levels of kitchen waste along with 10% green berseem improves the DM intake, growth and FCR than that of the control diet. During phase II, significantly (p<0.01) highest overall DM intake and overall daily weight gain was observed for Gr. I and no significant difference were observed among Gr. II, III and IV. However, no significant differences were observed for overall body weight gain and FCR. In conclusion substitution of concentrate for different levels of green berseem along with 50% kitchen waste reduced the DM intake and growth but improved the FCR than that of the control diet. It also decreases the back fat thickness however, differences among groups were non-significant. No significant differences were observed for other carcass traits. Significantly (p<0.01) lowest cost of total feed intake and cost per kg live weight gain was observed for group IV followed by group III, II and I in both phases of experiment. In conclusion green berseem could be incorporated up to 25% and kitchen waste up to 75% of total dry matter intake to make the feed economical and without affecting the performance of the animal adversely.

    Studies on performance traits of Sahiwal crossbred and hill cattle under farm conditions of Tarai region of Uttarakhand
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2013-04) Patoo, Raoof Ahmad; Singh, D.V.
    Present study was conducted from Oct. 2011 to Dec. 2012 on 720 records of Sahiwal, crossbreds and Hill cattle on their body morphometric, performance, urine, thermo adaptability and haematology under farm conditions in Tarai region. Majority of morphometric traits in all age groups were significantly lower (P<0.05) in Hill cattle than Sahiwal/ crossbreds, were higher for crossbreds in aged animals and in males. Colostrum of Hill cows was richer in protein (9.27±0.02 %), fat (5.92±0.15 %), lactose (3.35±0.31 %), total solids (18.33±0.35 %) and ash (0.88±0.08 %) than crossbreds. Milk of Hill cows had high protein, fat, SNF, TS as compare to crossbreds and had lower pH (6.41±0.04), electric conductivity (2.31±0.08 mhos) and somatic cell count (1.19±0.06 x105 cells/ml), making them less prone to mastitis. Age at first calving of Sahiwal, crossbreds and hill cows were 1338.67±34.23, 1041.86±27.45 and 1403.45±18.71 days, service period as 246.64±2.15, 225.45±5.18 and 121.78±3.14 days, lactation length as 280.32±6.52, 331.12±5.81 and 270.56±6.78 days, total lactation milk yield as 1536.74±65.64, 2768.84±95.72 and 340.12±27.45 kg, daily milk yield as 6.52±2.65, 9.64±3.45 and 1.35±2.45 kg, peak milk yield as 8.75±3.65, 13.83±4.45 and 2.51±6.71 kg, days to attain peak milk yield as 54.12±7.21, 68.67±6.35 and 38.75±12.23 days, dry period as 220.67± 2.74, 106.56±4.67 and 126.45±5.42 days, calving interval as 489.46±3.82, 469.13±2.64 and 462.45±5.45 days and birth weight as 20.12±2.56, 25.41±1.86 and 12.24±2.41 kg, respectively, making Hill and crossbreds cows efficient reproducers and producers. Urine of Hill cows had lower pH (7.616±0.052), total solids (5.938±0.037 %), urea (256.904±0.181 mg/dl), creatinine (27.020±0.119 mg/dl), total protein (5.686±0.036 mg/dl), and ash per cent (1.969±0.043 %) compared to crossbreds. Crossbreds had higher rectal temperature, respiration and pulse rate in summer, rainy and winter season than indigenous cows. Heat tolerance indexes and physiological parameters indicated that Sahiwal was more heat resistant, followed by Hill cattle and crossbred in hot humid climatic condition of Tarai. Hill cattle had higher haemoglobin content, packed cell volume and total erythrocyte count as compared to crossbreds and Sahiwal cows during all seasons, which perhaps make them adapted to hill terrains and harsh management conditions. Studied parameters indicated that Sahiwal and Hill cattle are important indigenous breeds requiring further attention for their improvement.
