Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    STUDIES ON USE OF SOME PHYTOGENIC MATERIALS AS CATTLE FEED PRESERVATIVES.
    (CSKHPKV, Palampur, 2019) Rana, Divya; Rani, Daisy
    This study was conducted to generate information regarding use of some phytogenic materials as cattle feed preservatives with the objectives to study changes in chemical composition of concentrate feeds preserved with plant materials; to study the effect of preservatives on in-vitro digestion of feeds; to study effect of promising preservative on nutrient utilization in ruminants and to study the economics of use of preservatives on growth performance of calves. Calcium propionate @ 0.1 percent, curry leaves @ 2 percent, mint leaves @ 1 percent, seabuckthorn leaves @ 2 percent, eucalyptus leaves @ 2 percent, turmeric rhizome powder @ 1 percent and neem leaves were added @ 2 percent and they were designated as PC, C, M, S, E, T and N, respectively. Basal feed was designated as NC. Effect on physical and chemical composition of feeds was studied up to 6 months period. In-vitro gas production study was conducted bimonthly for dry matter and organic matter digestibility. Digestibility-cum-metabolism trial was conducted by using NC, PC, N and T with wheat straw as source of roughage in 4 groups of calves with 5 calves in each group. A growth study was conducted on same groups of growing calves for 12 weeks period by using TMR containing concentrate with PC, N and T. Economics of use of the phytogenic preservatives in growing calves was calculated. On the basis of effect of phytogenic preservatives on shelf-life of concentrate feeds, treatment T and N had rank 1 followed by PC; M and S; C; NC and E in decreasing order. The feeds could be very well preserved up to 4 months after preparation under the weather conditions of Palampur, without affecting the in-vitro digestibility of DM and OM. The treatment T significantly (P<0.05) increased the digestibility of OM, CF and NFE in the growing calves. Nitrogen retention was not affected by the use of PC, N and T. Energy content of feeds of N and T treatments were significantly (P<0.05) higher than NC. The use of Calcium propinate, Neem and Turmeric resulted in lowering the expenditure of feeding to get 1 kg body weight by 10.65, 8.59 and 6.53 percent, respectively compared to NC. As the shelf-life study was conducted from February to August, there was a great change in environmental condition during last 2 to 3 months due to monsoons, therefore research work is needed to be conducted on the effect of phytogenic preservatives on shelf-life of feeds which are prepared and stored during rainy season.
