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.

    GALACTOGENIC AND REPRODUCTIVE CHANGES AFTER HORMONAL INDUCTION OF LACTATION IN ABANDONED COWS
    (CSKHPKV, Palampur, 2013-10) Bangthai, Ajit; Sood, Pankaj
    ABSTRACT The present study evaluated efficacy, udder secretory characteristics, milk quality and change in reproduction status following artificial induction of lactation using two different protocols. The Protocol 1 comprised of diethylstilbestrol, hydroxyl progesterone caproate, dexamethasone and reserpine administered over a 19 day period in 23 cows (20 raised in goshalas G1; 3 by individual farmers G2). Protocol 2 did not have reserpine; the remaining drugs, alike the first protocol, were administered over a 13 day period in 22 cows (19 raised in goshalas G3; 3 by individual farmers G4). All the cows, primarily Jersey crossbreds, were infertile, non-pregnant (cycling: n = 44; anestrus: n = 1) and non-lactating. The day of first injection was considered as day 1. Induction of lactation was successful (milk production of 1L/d) in 30%, 100%, 21% and 100% respondents in G1, G2, G3 and G4, respectively. Initiation of lactation began from day 10.0 ± 1.7 to day 12.3 ± 1.4 and did not differ between groups. There was a progressive increase in milk yield from day 15 to day 75 recorded at 15 day intervals. The milk yield between G1 versus G3 and G2 versus G4 was similar, but higher (P=0.10 atleast) in the latter subset of cows. The maximum yield (L/d) was 2.50 ± 0.3, 5.20 ± 1.30, 1.57 ± 0.19 and 5.2 ± 1.5 in G1, G2, G3 and G4, respectively and was observed at day 60 or 75. Failure of induction in non-respondents and low milk yield in G1 and G3 was probably due to a low live weight and/or BCS. Another group of 5 normal postpartum cows (control) was compared with the induced cows for certain plasma and milk parameters. The plasma and milk concentrations of Na, K and Mg did not differ much at days 5, 15, 30, 35, 50 and 75, except for a varyingly low plasma and milk Ca in G1 and G3. The milk estrogen declined from day 15 or 30 and did not differ amongst groups at days 50 and 75. The milk progesterone was low (P<0.01) in control than the induced groups, each of which, however, did not differ at different lactation days. The plasma IGF-1 concentrations were higher than milk at day 5 and 35. The milk IGF-1 concentrations declined from day 5 to day 35 in the control and induced cows. The specific gravity and fat percentage between control and induced milk was similar on days 15, 30 and 50. The reproductive status of all the induced cows in the gaushalas did not change, whereas 3 out of 6 cows with farmers became pregnant. In conclusion, the cows with farmers than in gaushalas exhibited a greater success and more milk, with no additional benefit of reserpine. The milk appeared to be safe for human consumption after 30 days of induction. Settling of pregnancies in the infertile cows was the added advantage of induced lactation.
