Influence of egg sperm penetration on Histological testes traits in White Leghorn Cocks

Abstract

This study was conducted at the Poultry Farm of the Animal Resource Department, College of Agriculture, Baghdad University, during the period from 8/10/2007 to 28/3/2009, to study the influence of egg sperm penetration on histological testes traits in White Leghorn cocks. The results as follow: 1) The means of testis weight, and relative weight in Hi treatment 13.26 gm and 9.80 gm/ kg of body weight, respectively. the semeniferous tubules diameter was 207.34 micron, lumen diameter 83.66 micron, and germ cells 115. 16micron. 2) The means of volume density for total semeniferoustub tubule:- spermatogonia, spermatocyte, spermatides, sperm, sertoli cells, vacuoles, lumen and basement membrane were: 15.23, 18.10, 14.53, 15.45, 20.23, respectively, whereas the relative weight were 1.49, 1.77, 1.46, 1.51, 1.98, respectively. 3) There is significant differential (P < 0.05) for volume density and the relative weight, leydige cells (13.09, 1.28), compared with Lo and Co treatment.
