Abstract

The activity of sperm cells after thawing depends on the ratio of reactive oxidant species and antioxidant system. The aim of the present study was to evaluate the effect of catalase (alone or combined with tryptophan as antioxidants) added to the extender on the livability of cryopreserved cattle...

Abstract

Cryopreservation induces sublethal damage to the spermatozoa, which leads to their reduced fertile life. The objective of this study was to investigate the effect of taurine, hypotaurine and trehalose as antioxidants on the function of the freezing-thawed sperm in Korean Jeju Black Bull. The semen...

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, ...
