Abstract - The quality of frozen-thawed semen collected from two different breeds of the buck was assessed based on plasma membrane functional integrity percentages, progressive motility percentages, sperm kinetic velocity and fertility after artificial insemination (AI) in Black Bengal Does. The fitness of a commercial semen extender (Andromed) was also evaluated in comparison to a traditional semen extender (Tris-citrate-fructose buffer). Collected and examined semen were used for AI in 36 Black Bengal does with natural heat. Results showed that the sperm plasma membrane functional integrity, progressive motility, sperm kinetics parameters such as beat cross frequency (BCF), linearity (LIN), straightness (STR), average path velocity (VAP) in fresh Boer semen was significantly higher than that of Jamnapari. There were no significant (P > 0.05) differences between frozen-thawed semen of Boer and Jamnapari buck in terms of CASA parameters except for BCF, LIN and VAP. However, Andromed diluted semen was found better in quality than that of semen with traditional extender irrespective of breeds of bucks. The study reports that there is no significant difference among pregnancy rates of Black Bengal does inseminated with Boer and Jamnapari buck semen and satisfactory pregnancy rate could be obtained after AI with Andromed diluted frozen-thawed buck semen than that of traditional semen extender. So, the Andromed could be an alternate extender in freezing buck semen.
