Abstract | Selection of buck is the starting point in goat development program.The aim of this study was to select of indigenous breeding buck at the Coastal areas of Bangladesh. A total of 20 bucks were examined and evaluated for the breeding efficiency considering the different factors such as pedigree, age, body weight, libido, hoof conformation, scrotal texture and circumference, no return rate etc. Out of these 20 bucks, 10 bucks were selected on the basis of scrotal circumference (SC) >18cm. Then these 10 bucks were under taking for checking their fertility through calculating the non-return rate (NRR).The SC of B-1, B-2, B-3 and B-4 were 20.2, 20.1, 21.2 and 20.2 cm, respectively. The mean ±SD of SC was 20.43±0.52. The testiculo-epididymal length (TEL) of B-1, B-2, B-3 and B-4 were 11.1, 10.8, 11.8 and 10.4 cm, respectively. The mean ±SD of TEL was 11.03±0.59. The NRR of B-1, B-2, B-3 and B-4 were 80%, 70%, 90% and 70%, respectively.In case of pregnancy per NRR in B-1, B-2, B-3 and B-4 were 100%, 100%, 89.89% and 85.71%, respectively.Conclusion: It may be concluded that the SC, TEL affect the breeding potentiality of buck. Further study with analysis of semen volume, morphology, sperm motility, mass activity, viability will be performed.
