Abstract
The study aimed to assess the conception rate as an indicator of the success of Artificial Insemination (AI) of selected AI points of Sylhet district. Three years (2020 -2022) data from Khadim Nagar, Mirza Jungle, and Jaintyapur have been used for this study. Result revealed that Jaintyapur point achieved highest conception rate (98.96%) and lowest found at Khadim Nagar (86.93%). On the other hand, among the total inseminated cattle, 95.6% were a crossbreed. In contrast, 96.2% were local breed. However, while comparing the different semen used for AI, insemination with D×128 attained conception rate 100% at Jaintyapur AI point. Whereas the lowest performance reported SL×788 as 90%. In the case of parity of the cattle, conception rate was 96.5% in first parity, 95.6% in second, 96.7% in third,97.2% in fourth and 65.5% in fifth. Overall, the success of AI in Sylhet district could be considered satisfactory.
