Studies on seminal attributes in relation to scrotal circumference in buffalo breeding bulls

Abstract

Seminal attributes and scrotal circumference was conducted on twenty five Murrah buffalo breeding bulls belonging to Central Semen Station, Bhopal. Five semen samples from each buffalo bull were collected at 7 days interval. Fresh semen was evaluated for volume, mass motility, sperm concentration, progressive motility, live sperm count and morphological abnormalities. The mean volume, mass motility, progressive motility, sperm concentration, live sperm count and total abnormal sperms were 2.71±0.112, 3.34±0.073, 68.4±1.30, 978.9±34.37, 89.52±0.38, and 8.82±0.873%. Significant (P<0.05) variation was observed between the bulls with regard to sperm abnormalities. However, non-significant difference was observed for volume, sperm concentration, mass motility, progressive motility, and live sperm count. The overall mean sperm abnormalities found for abnormal head, middle piece and tail were 1.68±0.160, 2.0±0.238, and 5.12±0.475 percent, respectively. Tail abnormalities differed significantly between bulls.
