AbstractThe present study was aimed to improve the quality of Shami goat semen diluted with Tris diluent by adding bovine serum albumin. In the current study, six male goats were used. Semen was collected using artificial vagina of one ejaculate per week of every male included in this study. This study was performed during the breeding season from 1 10 2012 to 1 12 2012. In this study, two semen diluents were use first; Tris- fructose- egg yolk 2.5% and second Tris - fructose - 2.5% egg yolk with 1% of bovine serum albumin. Diluted semen samples were cooled gradually and stored at 5 ° C. Cooled diluted semen samples were examined every 24 h of storage to 144 h. These tests includes the proportion of live sperm and the percentage of secondary abnormalities of the sperm, the percentage of sperm acrosomal defects and percentage of progressive motility using a computer-aided sperm analysis. These results showed that the addition of bovine serum albumin with egg yolk to semen of male goats led to improved qualities of semen significantly (P<0.05) including the proportion of live sperm and the percentage of secondary abnormalities of the sperm, the percentage of sperm acrosomal defects and percentage of progressive motility. It could be concluded from the results of the current study, the possibility of storing goat semen for more than six days with alive sperm of more than 50% and the percentage of the progressive motility of more than 40% when adding bovine albumin serum to dilute goat semen at 1% level and this result has not reached by any previous study.
