Abstract

The current study aimed to determine the genetic polymorphism of sex determining factor or sex determining region, Y-chromosome gene (SRY) and the association of semen parameters with field fertility of Egyptian buffalo bulls. Fresh semen ejaculates (n=264) from 66 bulls were collected and evaluated. The bulls (n= 56), with ejaculates ≥ 60% motility, were categorized according to pregnancy rate (PR) into high (PR≥50%, n=47) and low (PR
