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.

    Study on effect of CIDR insertion during early postpartum phase on reproductive efficiency in dairy cows
    (Palampur, 2021-09-09) Kour, Popandeer; Singh, Madhumeet
    The present study was conducted on dairy cows (N=20) reared at Institutional Livestock Farm Complex, CSKHPKV, Palampur, during the early post-partum phase i.e. day 35. The selected cows were randomly distributed among 3 groups, viz. two CIDR treatment groups and one control group. Treatment group 1 (CIDR+FTAI) consisted of 7 cows, each receiving Controlled Internal Drug Release (CIDR) insert for 9 days only whereas treatment group 2 (CIDR-PGF2α+FTAI) comprised of 6 cows in which resynchronization with CIDR from day 18-26 during subsequent mid-luteal phase after CIDR removal and cows in the control group (n=7) did not receive any treatment. Transrectal ultrasonography was done to assess the effect of treatment on follicular growth on different days of synchronization protocol as well as assessment of ovarian functional status by using Color Doppler portable ultrasound at 7.5 MHz frequency. Cervical discharge samples in both treatment groups were taken for culture sensitivity test after onset of estrus (AI day). The objectives of the current study were to assess the efficacy of CIDR-based protocol applied during the early post-partum phase on induction of estrus and record the effect of protocol on ovulation and conception rate in dairy cows. In the present study, estrus could be induced successfully in all the cows following CIDR treatment during the early postpartum period, however, artificial insemination was not done in some cows due to turbid discharge (9/13). Standing heat and mounting were not the predominant signs of estrus following CIDR treatment during the early post-partum period as compared to the control group, whereas, vulvar edema and cervicovaginal mucus were the common signs. The mean diameter of the pre-ovulatory follicle was numerically higher (p>0.05) in both the treatment groups as compared to control group cows. Also, duration to first behavioural estrus was non-significantly lower (p>0.05) in CIDR treatment groups whereas the days open were numerically lower (p>0.05) in the CIDR+FTAI group only as compared to control group cows. The fluoroquinolones (Levofloxacin, ofloxacin, and Enrofloxacin) were recorded as the most sensitive as ant
