A study was conducted to explore the utility of different drinking water temperature, viz. ambient water temperature (10.25±0.28°C, T1), 15-20°C (T2) and 35-40°C (T3) during winter at IVRI, Mukteshwar campus on 18 crossbred (HF × Haryana) lactating cows. They were divided into 3 groups of 6 each and various parameters were studied. At open environment maximum temperature, minimum temperature and mean relative humidity were 11.81±0.45, 1.52±0.27°C and 57.43±2.79%, respectively, the corresponding values for microclimate were 16.61±0.36, 6.68±0.61°C and 86.75±0.55%. Average water intake per cow per day was significantly higher in T3 (40.66±0.55) and compared with cows in T1 (38.63±0.42) and T2 (37.53±0.47). Dry matter intake was more for cows in T3. Daily mean milk yield for the cows in T3 (7.56±0.18 litre) was significantly higher than T1 (6.95±0.16 litre) and T2 (7.06±0.17 litre). Milk SNF, protein and total solids percentages were significantly higher for cows consuming warm drinking water in T2 (15-20°C) and in T3 (35-40°C) than cows consumed ambient cool drinking water. Cows in warm drinking water groups showed relatively more gain in body weight compared to cows provided with ambient cool drinking water. It was concluded that the crossbred cows consuming warm water (35-40°C) performed better than the cows consuming comparatively cold water.

India although has achieved self sufficiency in food grains, it has to solve the problems of protein-energy malnutrition for millions of people. Presently, poultry industry has emerged as a big hope, which can meet not only the protein requirement to millions but can provide employment and thereby, livelihood security. India is the 3rd largest producer of eggs and holds 5th position in poultry meat production in the world. Developments like emergence of molecular markers, structural and functional genomics, bioinformatics etc. in the field of the biotechnology have provided ample opportunity to peep into the molecular architecture of the individual birds. Improvement of poultry birds all together can be achieved through conventional breeding approach, but amalgamation of conventional and molecular approach can generate further improvement of birds in sustainable manners, which in turn augment productivity of the poultry very rapidly and efficiently bypassing the impact of climate change being faced by the whole world today. © 2014, The National Academy of Sciences, India.

This study was conducted to evaluate the effect of mineral and antioxidant supplementation on growth, reproductive performance and physiological adaptability of heat-stressed Malpura ewes. The study was conducted for a period of 21 days in 21 adult Malpura ewes. The ewes were randomly divided into three groups with seven animals each viz. GI (control; n = 7), GII (heat stress; n = 7) and GIII (heat stress + mineral and antioxidant supplementation; n = 7). The animals were stall fed ad libitum with the diet consisting of 70% roughage and 30% concentrate. GI ewes were maintained under normal controlled condition in the shed, while GII and GIII ewes were subjected to heat stress by exposing them to 42 °C in the climatic chamber. The parameters studied were feed intake (FI), water intake (WI), body weight, body condition score (BCS), physiological, biochemical and endocrine responses. Heat stress significantly altered FI, water intake, BCS, respiration rate and rectal temperature in the afternoon, oestrus duration, estradiol, progesterone, Hb, PCV, plasma glucose, total protein, cortisol, T3 and T4 levels while mineral and antioxidant supplementation ameliorated this heat stress effect on the parameters studied. Further, the adverse effect of heat stress on the productive and reproductive efficiency of Malpura ewes was reduced considerably by mineral mixture and antioxidant supplementation. This is evident from the non-significant difference in BCS, oestrus duration and plasma estradiol between GI and GIII in this study. Hence, it is very pertinent to conclude from this study that mineral mixture and antioxidant supplementation were able to protect Malpura ewes against heat stress. © 2013 Blackwell Verlag GmbH.

Genetic parameters of growth traits were estimated in the GermanAngora rabbit reared in the sub-temperate region of India. Estimates of (co)variance components were obtained for body weights at weaning (42 days) and post-weaning at 84, 126 and 168 days. A total of 8,324 animal records were used for the analysis of these traits. The data were analyzed by restricted maximum likelihood (REML) fitting six animal models with various combinations of direct and maternal effects. Alog likelihood ratio test was used to select the most appropriate univariate model for each trait. Direct heritability estimates were observed to be moderate for the traits under study. Heritability estimates for weaning (42 d), 84, 126 and 168 d weights obtained from the best models were 0.25±0.05, 0.17±0.05, 0.21±0.06 and 0.12±0.05. Maternal effects had higher importance at weaning, and declined with the advancement of age. Significant maternal permanent environmental effect on weaning and post-weaning weights was a carryover effect of maternal influences during pre-weaning age. The estimated repeatabilities of doe effects on body weights were 0.37, 0.22, 0.18 and 0.28 at weaning, 84, 126 and 168 d body weight, respectively. Results indicated that modest rate of genetic progress is possible for body weight traits of Angora rabbit through selection. Similarly, these growth traits could be included in selection criteria along with wool traits for early selection of the animals.

After an initial survey on feeds and feeding practices at Kumaon Himalaya, the potential of oak leaves feeding was evaluated in six native heifers (Bos indicus; 101.5 kg BW, 18-24 months) in a partial switch-over design involving two animals each on each treatment at a time. The feeding treatments involved high and low levels of oak leaves (Quercus leucotrichophora, oak leaves (OL)) supplemented to local mixed grass hay (GH) which were GH (G1), GH + low level (42.5 %) of OL (G2) and GH + high level (63.6 %) of OL (G3). The feeding trial for each treatment was conducted for 40 days that ended with a digestibility trial of 6-day duration. The dry matter (DM) intake (kg/day) was non-significantly higher in G3 (3.52) than G2 (3.11) and G1 (2.96). Intake of crude protein (CP) (g/day) was significantly (P < 0.001) higher in both G2 and G3 than G1. The digestibility of DM, CP, organic matter, ether extract and total carbohydrates increased (P < 0.001) linearly in OL-fed groups as compared to control. The total digestible nutrients (TDN) (kg/day) intake was significantly higher (P < 0.05) in G3 compared to G1, but it was comparable between G1 and G2. Intake of DM, CP, digestible CP (DCP) and TDN/metabolizable energy (ME) per kilogram metabolic body weight was significantly higher (P < 0.01) in G3 than G2 which in turn was also higher (P < 0.01) than G1. The animals under G1 had negative gain (-50 g/day) compared to 146 and 306 g/day in G2 and G3, respectively. Feeding of OL reduced serum urea and creatinine level and supported serum protein concentration better in G3 compared to G2. The feeding of cattle on GH alone was lacking in both energy and protein for sustaining minimum levels of production, whereas in combination with OL at 36.4:63.6 ratios supported minimum level of production (ADG 300 g) with near nutritional adequacy for major nutrients (CP, DCP, TDN, ME) but with a caution for the minor nutrients like calcium and phosphorus that need to be supplemented. © 2012 Springer Science+Business Media B.V.

Pashmina, a finest natural animal fiber is utilized for preparation of world famous Kashmiri pashmina shawls by traditional practices. Hand spinning is one of the important processing step, wherein fibers are converted into a fine yarn on a traditional spinning wheel (yander). The task is usually carried out by women folk. It is a laborious process resulting in a lot of physical stress affecting the efficiency of artisans. An innovative charkha has been fabricated to reduce the physical stress and its effect on the spinning efficiency and remuneration of artisans over traditional one was evaluated. The study revealed that innovative charkha was efficient in terms of time consumed for spinning by 73.50% over traditional one besides decreasing physical drudgery. In terms of income, there was an increase of 146% over traditional one for same period of time without deteriorating the quality of yarn. © 2013 Copyright The Textile Institute.

The positional candidate gene DGAT1, within QTL of BTA14, harboring a lysine to alanine substitution (K232A) is significantly associated with milk production traits. The present investigation was undertaken to estimate the frequency of the DGAT1 K232A polymorphism in Indian zebu breed, Sahiwal (B. indicus; N=51) and crossbred, Frieswal (HF X Sahiwal; N=126) cattle using PCR-RFLP technique. Detection of allelic variation at nucleotide positions 10433-10434 of the DGAT1 gene was performed by restriction digestion of a 413 bp PCR product with Cfr I. The frequency of A allele in Frieswal and Sahiwal cattle was 0.36 and 0.04, respectively. Although all the three genotypes were observed in Frieswal cattle, however, no animal of AA genotype was found in Sahiwal cattle and only four animals were of heterozygous genotype (AK). The sequences, specific to K and A allele, were submitted to GenBank (JF345253 and JF345254). Because of very high frequency to almost fixed nature of K allele in Sahiwal and other well defined Indian cattle breeds, DGAT1 K232A polymorphism may not be a suitable candidate for selection purpose. Nonetheless, the results could be used to guide association studies between this locus and milk production traits especially in Frieswal.

Reproductive performances were studied in goat following synchronization of oestrus with progesterone-impregnated vaginal sponge plus PMSG and HCG. Five Assam goats, 2-3 years of age, at about 45 days post-parturition, reared under semi-intensive were treated with progesterone-impregnated vaginal sponges kept in situ for 9 days. On the day of sponge removal PMSG was injected intramuscularly @ 300 I.U. per animal and also injected HCG intravenously at 6 hr post oestrus @ 500 I.U. The A.I. was done with Beetal buck semen at 24 and 36 hr post onset of oestrus. Five other Assam goats of similar age, reproductive status and rearing condition served as control. All the experimental goats exhibited oestrus following treatment and the mean interval between end of PMSG treatment and onset of oestrus was 34.40 ± 4.16 hr, where as the control animals exhibited oestrus at a mean interval of 68.80 ± 6.71 days after last kidding. The duration of oestrus was recorded to be longer in treated group (40.00 ± 4.60 hr) than in control goats (36.40 ± 3.12 hr), however, the difference was not significant between the groups. The mean body weight of male and female kids born was 0.90 ± 0.04 and 0.71 ± 0.05 kg and 1.00 ± 0.04 and 0.86 ± 0.24 kg in treated and control group, respectively. A total of 12 and 9 kids were born from 5 does each of treated and control group. The sex ratio was 1:1 and 1.25:1 in treated and control group, respectively. It was concluded that progesterone-impregnated vaginal sponge was effective to induce pronounced synchronized oestrus in Assam goats and to increase the litter size by 33.33 per cent.
