Abstract
Background: The selection of breeding bulls based on the association of sexual behaviour, seminal attributes and conception rate are more important and economical. However, information on association of sexual behaviour and seminal attributes with fertility in buffaloes particularly with reference to Jaffarabadi buffalo bulls is meager. Methods: The study was carried out to assess the association of sexual behaviour and seminal attributes with first service conception rate (FCR) of Jaffarabadi buffalo bulls. A total of 192 semen ejaculates were evaluated and cryo-preserved. First AI conception rate (FCR) was carried out on 800 Jaffarabadi female buffaloes inseminated with frozen-thawed semen and pregnancy was confirmed by per rectal palpation at 2 months post-insemination. Result: The results indicated that both sexual behaviour and seminal attributes were associated with fertility in Jaffarabadi buffalo bulls.
