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.

    (CSKHPKV, Palampur, 2019-08-19) Bashir, Sadiya; Singh, Madhumeet
    The present study was conducted in Livestock Instructional Farm Complex and Teaching veterinary clinical complexof College of Veterinary and Animal Sciences Palampur, Himachal Pradesh. Under this study, 50 apparently healthy silent estrus cows were screened for the presence of functionally active mature corpus luteum by Trans- rectal ultrasounonographic scanning. Equal and random distribution of these cows was done into 5 groups, viz. three hormonal treatments, one nutritional supplementation and one control groups. Ten cows in Group 1 (G1) received 500 mcg single mid-cycle injection of PGF2α (Cloprostenol) only. In Group 2 (G2), 10 cows which were initially treated with single mid-cycle injection of PGF2α for the lysis of CL were administered 10μg Buserelin acetate 72 hours later along with FTAI and repeat AI 24 hours thereafter. Group 3 (G3) cows were given single mid-cycle injection of PGF2α with subsequent administration of 1500 IU hCG 72 hours post induction along with FTAI, followed by repeat AI 24 hrs later. In Group 4 (G4), 10 cows were supplemented with 50 grams of mineral mixture, along with 10 ml To alternate days thrice and inseminated at observed estrus and in Group 5 (G5), 10 cows were maintained as untreated control group and did not undergo any treatment. These cows were inseminated at the observed estrus. The Incidence of silent estrus was recorded during clinico-gynaecological camps (n=89) conducted in different districts of Himachal Pradesh. Estrus induction rate of 100 per cent was recorded in G1, G2 and G3 cows, whereas, it was only 55.55 and 40.0 percent in G4 and G5 cows, respectively. Conception rate of 40.0, 45.5, 60.0, 40.0 and 25.0 per cent was recorded in G1, G2, G3, G4 and G5, respectively. Subsequently, 50.0, 80.0, 75.0, 66.66 and 0 percent of the non- pregnant cows displayed signs of heat during successive estrus in G1, G2, G3, G4, G2 and G5 cows, respectively. Mean ovulatory follicular diameter of induced estrus cows was recorded as 11.96±0.36 mm and did not differ significantly (p>0.05) from cows under spontaneous estrus group (12.06±0.73 mm). However, significant difference (p<0.05) was found between the mean ovulatory diameter of pregnant ( 12.86±0.52a) and non-pregnant (11.58±0.30b) cows.
