Abstract

The recent study was designed to estimate the effect of season on dogs' semen parameters in mature and pubertal males, before and after hormonal adding and precede the sperms viability after collection. Twenty local dogs were divided into two equal groups the first one aged between 2-3 years which represent the mature dogs group, and the second group aged 9-12 months which considered as newly pubertal males. This study was done in dogs cages in College of Veterinary Medicine – University of Baghdad from 1/2/2015 to 1/2/2016. The semen was collected by using artificial vagina twice weekly. The physical examination (semen volume, colour, odour, debris and pH) and also the microscopical examination (mass motility, individual motility, sperm numbers, viability and deformities) and precede both the viability of sperms every hour till ceased of individual motility and the effect of adding of oxytocin and prostaglandine f2α. The herein study indicated that there were a significant decrease in sperms mass motility, individual motility, sperms numbers and viability during summer season, nevertheless, the deformities increased significantly during the summer in both males groups. The deformities show significant differences between mature and pubertal males. The individual motility indicated an increase after hormonal adding to the semen, the individual motility also ceased after 12 hrs from collection in all seasons. This study concluded that the male dogs could breed during the different seasons of the year, and the summer season had negative effect on male reproductive fertility. The hormonal adding lead to increase the individual motility also the maximum period of survival of the sperms after collection not extended more than 12 hrs.
