Abstract The histological study showed that The testis is surrounded by thin capsule consist of three layers with loses for the septa and lobules. The testis is consist of seminiferous tubules separated by interstitial area with spaces which contain the interstitial tissue and clusters of lydig cells which lining with seminiferous epithelium and large sertoli cells and surrounded by longitudinal myoepithelial cells adhered of basement membrane. The spermatogenesis in racing pigeon begins from spermatogonia and ending with the composition of sperm, where the spermatogonia are classified into spermatogonia type A, spermatogonia type І and spermatogonia type B. The primary spermatocytes pass through six different phases include preleptotene, leptotene, zygotene, pachytene, diplotene and diakinesis phases which ending with composition secondary spermatocytes which give rise to spermatids. The spermatids pass through metamorphosis include Golgi phase, Cap phase, Acrosomal phase, and maturation phase give rise to sperm

ABSTRACT poultry sector is considered is one of the important production sectors and a basic component in nutrients some countries and a source to provide foreign currency as well as achieving food security. The aim of this study is to shed light on the performance of this sector and calculate the comparative advantage of broilers production in Iraq and consequently to conclude the nature of its efficiency domestically and its competitiveness on world level. This could be achieved by using Policy Analysis matrix technique (PAM) . the results showed that revenue in private prices was about (31.122) million dinars / hall when the private profits are (4.847) million dinars / hall. On other side the social profits were positive while net transfers (L) were about (-5.915 ) million dinars / hall which could be explained that the effect of total policy followed by government is against the interests of domestic broilers producers in short run. The result of nominal protection coefficient for output (NPCO) was positive and less than one (0.84) which means that protection was negative for domestic producers. On other hand the nominal protection coefficient for tradable input was positive and less than one (0.95 ) which means that there was support for such input while the result of domestic resource cost (comparative advantage indicator) was positive with a value of (0.33) which means that the broilers domestic production has a comparative advantage also the effective protection coefficient value was (0.70) which means the absence of government support for broilers production . the results showed that private cost ratio was (0.57) which means that investment in broilers projects achieved profits for private investors and has domestic competitiveness .the study had arrived according to results at some conclusions and recommendation
