Abstract

The aim of the study was to compare the pattern and density of the vascular layer of testis in some farm animals. The study was conducted on 50 specimens (10 for each species). The collected specimens are divided into two equal groups; the first group is used for gum milk latex injection while the other group is prepared for corrosive cast technique. The differences in the vascular pattern of the vascular tunic among the various species of farm animals are contributed to the architectural pattern of the marginal artery as well the mode of its termination so the current study suggest four patterns. The density of the tunica vasculosa in buffalo is pronounced in the distal third of both lateral and medial surfaces of the testis while it appears scanty in the proximal two third of both surfaces. In ram it is more pronounced than in buffalo while in camel the density of the tunica arteriosa testis is poor. In donkey the density of the tunica arteriosa testis is more pronounced in the distal two third of both surfaces of the testis. The density is poor and less pronounced in rabbit.
