ABSTRACT
This study evaluated the effect of breed, body condition score and ascorbic acid supplementation on the semen quality of breeding bulls. A total of 8 adult (≥2 year) bulls (2 each from Jersey, Friesian, Sahiwal and cross bred) were selected with body condition score (BSC) at a scale of (0-5). The results showed that mean semen volume was significantly (P<0.05) high in Friesian bull. Sperm concentration and motility were significantly (P<0.05) high in Jersey bull while live sperm percentage was significantly (P<0.05) high in Jersey bulls and sperm abnormality was significantly (P<0.05) high in Sahiwal and Friesian-Sahiwal cross. In addition, semen quality was improved in all the breeds after supplementation of vitamin C. There was no significant effect of BCS on the sperm quality of bulls. The results give important information regarding the semen quality of different breeds of bulls under heat stress condition.
