Abstract: The present study was planned with the objective to investigate the performance of buffaloes bred with sex sorted semen in Southern states of India. The data used in the present investigation were collected from 1,037 villages in the jurisdiction of 130 Cattle Development Centres (CDC) being operated in 128 tehsils of 25 districts in Andra Pradesh, Karnataka and Telangana states of Southern India. A total of 7,784 artificial inseminations were performed on 7,248 buffaloes owned by 6,300 farmers during the years October 2019 to September 2023. The effect of different factors such as state, animal owner gender, animal breed, lactation order, heat stage at the time of sex sorted A.I., animal body condition score, sex sorted A.I. season and economic status of animal owner was assessed on the conception rate of buffaloes which were inseminated with the sex sorted semen. Logistic regression analysis was used to compute the odds ratio and probability of conception rate. The results revealed that the overall mean conception rate was 40.54±0.01 percent and it was recorded significantly higher in buffalo animals from Telangana state (41.54%), animals bearing forth lactation (53.56%), animals exhibiting mid heat (43.86%), buffaloes having two ribs exposed (41.78%) and buffaloes inseminated during winter season (42.53%), and conception rate non-significantly recorded highest in animals reared by female owners (42.16%), Pandharpuri buffaloes (46.15%) and animals owned by below poverty line families (40.88%). Statistical analysis of data showed that state, lactation order, heat stage at the time of sex sorted A.I., animal body condition score and sex sorted A.I. season had a significant effect on conception rate of buffaloes from Sothern states of India inseminated with sex sorted semen.
