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.

    EFFICACY OF SOME OVULATION SYNCHRONIZATION PROTOCOLS IN DAIRY COWS DIAGNOSE D WITH POST PARTUM SUB CLINICAL ENDOMETRITIS
    (CSKHPKV Palampur, 2020-12-03) SHARMA, AKSHAY; Singh, Madhumeet
    The study was conducted on 45 post-partum dairy cows at Livestock Farm Complex, Dr. G.C. Negi College of Veterinary and Animal Sciences, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur. Assessment of energy reserves i.e. body condition score (BCS) and back fat thickness (BFT), was done at weekly interval up to 8 weeks post-partum along with serum leptin estimation to investigate its association with occurrence of sub-clinical endometriris (SCE). For diagnostic purpose, endometrial cytology via cytotape method was carried out as confirmatory test for diagnosis of SCE i.e. polymorphonuclear cells (PMNCs) proportion ≥1 per cent. Also, trans-rectal Doppler ultrasonography at a weekly interval i.e. day 0 to 56, along with B-mode for assessment of uterine involution and resumption of ovarian activity, was used. Serum inflammatory markers such as Interleukin-6 (IL-6) and C-Reactive protein (C-RP) levels were estimated for drawing a relation with SCE. MG6G and MG6GP modified estrus synchronization protocols were applied to study their effect on PMNCs proportion during SCE and post-partum reproductive performance. On the basis of endometrial cytology, the incidence of sub-clinical endometritis positive and clinical endometritis positive cows was 60 and 8.89 per cent, respectively at 8 weeks post-partum, however, the cows in sub-clinical endometritis negative group had an incidence of 31.11 per cent. BCS and BFT were significantly lower (p<0.05) in SCEP cows as compared to SCEN cows on the day 0 and 56 post-partum, however, serum leptin concentrations were significantly low (p<0.05) only on day 0 post-partum in SCEP cows. Haemodynamic indices i.e. Time averaged maximum velocity and Blood flow volume- Time averaged maximum velocity, and diameter of middle uterine artery ipsilateral to gravid uterine horn was significantly higher (p<0.01 & p<0.05) on day 0 and 56 post-partum in SCEP and CEP cows as compared to SCEN cows. Serum concentrations of IL-6 and C-RP were significantly higher (p<0.01 & p<0.05) in SCEP and CEP cows as compared to SCEN cows at 8 weeks post-partum. MG6G and MG6GP modified estrus synchronization protocols led to a significant (p<0.05 & p<0.01, respectively) reduction in PMNCs proportion and serum IL-6 concentration on the day of estrus in cows under SCEP group. MG6GP modified estrus synchronization protocol fared better in terms of achieving conception i.e. 60 per cent vs. 30 per cent in MG6G protocol and also, resulted in a significant decrease (p<0.01) in days open of SCEP cows as compared to cows under SCEP control and CEP group.

    EVALUATION OF INTRA-VAGINAL PROGESTERONE RELEASING INSERT IN REPEAT BREEDER COWS
    (CSHHPKV Palampur, 2020-10-05) CHANDEL, ANSHUL; Singh, Madhumeet
    The study was carried out on 43 repeat breeder cows selected from Teaching Veterinary Clinical Complex and Instructional livestock farm complex Chaudhary Sarwan Kumar Himachal Pradesh Agricultural University, Palampur along with nearby field veterinary institutions for the evaluation of controlled internal drug release (CIDR) insert. The selected cows were divided into four groups viz. Group 1 (G1; n=12) CIDR-PGF2α synchronization protocol and post-insemination CIDR insertion from day 4 to 13, Group 2 (G2; n=13) CIDR-PGF2α synchronization protocol and post-insemination CIDR insertion from day 12 to 21, and Group 3 and 4 control (G3 and G4; n=9 each) in which no treatment was given to cows and artificial insemination (AI) was done on the day of spontaneous estrus. Blood samples were collected at the time of post-insemination CIDR insertion, 72 h after CIDR insertion and 48 h after CIDR removal. Effect of treatment on follicular growth and corpus luteum development was assessed by trans-rectal ultrasonography (TRUS). Pregnancy diagnosis was done 45 days post AI by rectal examination and TRUS. Intra-vaginal CIDR insertion led to a higher conception rate in repeat breeder cows as compared to untreated cows under control group. Estrus synchronization with CIDR based protocols resulted in significantly lower (p<0.01-0.05) diameter of corpus luteum albicans as compared to nonsynchronized (control) cows at estrus. No significant increase (p>0.05) in progesterone concentration and corpus luteum size was recorded at different days of observations following post-insemination CIDR insertion in both the treatment groups as compared to control group. Subsequently pregnant repeat breeder cows following post-insemination CIDR insertion had a non-significantly (p>0.05) higher progesterone concentration and corpus luteum size at different days of observations in both the treatment and control groups as compared to non-pregnant cows. Also, mean pre-ovulatory follicular diameter was found to be non-significantly higher (p>0.05) in subsequently pregnant as compared to non-pregnant cows in treatment and control groups.
