Abstract

This study was carried out on semen of adult twenty four (eight Awasi, eight karadi and eight Arabi) rams, semen was collected by means of artificial vagina. Once weekly for one year period, the study included season variations in semen quality. The volume, percentage of sperm motility, concentration rate, live percentage was high in Awasi in spring, and low abnormalities from Arabi and karadi breeds. The spring was the best season in high quality of semen in three breeds.

Testosterone was high in blood plasma of Awasi rams. Moreover, Awasi had the highest AST enzyme concentration (6.7 IU/L). From these results we show that semen characteristics was highest in Awasi in spring in different regions of Iraq (north, medium and south).
