Abstract

Thirty-six ejaculates (3 ejaculates/bull) of pure and crossbred Jersey bulls were used to compare sperm attributes of frozen thawed semen. The seminal attributes viz. semen volume, sperm concentration, post thaw motility and acrosome integrity were similar (p>0.05) between the breeds, whereas,...

Abstract

The aim of this study was to value the in vitro induction by heparin of acrosome reaction in frozen semen from Brahman and Gyr bulls, as a method to estimate frozen semen fertility. Seven sexually mature Zebu bulls (4 Brahman and 3 Gyr bulls) were used in this study. In a post-thawing seminal...

Abstract

We investigated the use of duck egg yolk (DEY), Guinea fowl egg yolk (GFEY) and Indian indigenous hen (Desi) egg yolk (IDEY) in extender for improving the post-thaw quality of buffalo (Bubalus bubalis) bull spermatozoa, and compared it with commercial hen egg yolk (CHEY; control). For this purpose, ...
