Abstract:
The present study was conducted to compare various sperm morphometric parameters between high-fertile and low-fertile Mehsana buffalo bull. A total of twelve Mehsana buffalo bulls were selected based on their conception rate (CR) recorded under the field progeny testing program and divided into two equal groups (high-fertile - CR > 43% and low-fertile - CR < 35%). To compare various sperm morphometric parameters, 72 frozen semen samples, six from each bull was randomly selected. Smears of frozen-thawed semen was stained with eosin-nigrosin stain and various morphometric parameters viz. sperm head length, sperm head width, width at base, mid-piece length, ellipticity, elongation, head shape and head area were recorded. The mean value of sperm head width (µm), mid-piece length (µm), elongation (%) and head shape were significantly (p<0.05) higher in high fertile bull as compared to low fertile bull. While, width at base (µm) and ellipticity were significantly (p<0.05) higher in low fertile bull as compared to high fertile bull. Moreover, the sperm head length and head area differed non-significantly between high and low fertile buffalo bulls.
