Abstract

The aim of this study was to investigate the effect of two kinds of commercial egg yolk-free extenders: Bioxcell and AndroMed on in vitro sperm function of sheep. A total of 10 ejaculates were collected from 5 adult Iranian Zandi rams using artificial vagina. Semen samples were mixed and diluted with Bioxcell or AndroMed. Freezing was conducted using imv semi-automatic equipment. The percentage of motility and progressive motility of sperm were evaluated before freezing (at 37°C), after refrigeration (at 5°C) and thawing, and recovery rate was calculated. Data was analyzed using proc GLM of SAS. The effect of extender on sperm qualitative characteristics after thawing was significant. Mean percentage of motility, progressive motility and recovery rate were higher (P≤0.01) in AndroMed than Bioxcell. Results suggested that AndroMed in comparison with Bioxcell had more ability to preserve sperm quality during freezing process.
