In the present study, we have comparatively evaluated 3 diagnostic tests, viz. virus isolation, sandwich ELISA and multiplex PCR to detect foot-and-mouth disease virus serotype 'O' in clinical samples, isolated from Indian origin. Our results showed that multiplex PCR could detect FMD virus in the highest number of samples than rest of the two comparatively.

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.

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.

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.

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.
