Effect of α-Tocopherol in Tris-Aminomethane – Egg Yolk on the Semen Quality during Cold Storage in Boer goats

Abstract

The study was conducted to evaluate the effect of α-tocopherol in  Tris Aminomethane – egg yolk diluent at cold storage in Boer goats. The semen was collected from  Boer goats buck aged 1.5-2 years old,  with a body weight of 80-90 kg.  After evaluation of fresh semen, the semen was diluted with tris-aminomethane-egg yolk with a ratio of 1 : 10. The diluted semen then was divided into four groups containing 0.0 g; 0.2 g; 0.4 and 0.6 g α-tocopherol / 100 ml diluent, and stored at 5^oC for one hour before evaluation. The results showed that there was no significant difference in sperm motility, however the sperm viability and abnormality were significantly differences (P<0.01) between groups both before and 1-hour after storage at cold temperature.
