Abstract:
The present study was planned with the objective to investigate the social factors affecting the conception rate in Artificially Inseminated cattle under field conditions in Telangana state. For the present investigation data were collected from 733 villages in the jurisdiction of 49 Cattle Development Centres (CDC) being operated by BISLD Telangana with financial support by Karimnagar Dairy in 70 tehsils of Jagtial, Karimnagar, Peddapalli, Siddipet, and Sircilla districts. Total 40,693 artificial inseminations were considered as per the factors taken for study, performed on 32,121 cattle owned by 17,372 farmers from the years April 2019 to March 2021. The effect of social factors of the district, A.I. Technician education, distance covered for A.I., animal breed, lactation order, breed of bull used for A.I., A.I. sequence, A.I. season, estrous stage, and origin of animal was assessed. Logistic regression was used to compute the odds ratio and probability of conception rate. The results revealed that the overall mean conception rate was 46.23±0.25 percent and it was recorded significantly higher in animals from Karimnagar district (47.70%), inseminations performed by 12^th pass A. I. Technicians (47.58%), animals covered within the distance of 3 to 6 km (46.76%), non-descript cows (49.20%), heifers (49.13%), animals inseminated in summer season (47.77%), mid-heat animals (48.39%) and farm-born animals (48.59%) compared with the corresponding group of respective social factors. Statistical analysis of data showed that district, A.I. Technician education, distance covered for A.I., animal breed, Lactation order, A.I. season, estrous stage, and origin of animal had a significant effect on conception rate, however, the breed of bull used for A.I. and A.I. sequence did not affect conception rate.
