Abstract
Vit E is known as one of the most important antioxidant. It has been previously approved that cereal grains and leafy plants are considered as the main source for α-tocopherol (Vit E). One of the recommended therapies for male infertility would be the Vit E therapy. Following Vit E consumption the semen parameters such as sperm concentration, ejaculation volume, sperm progressive motility, and in vitro function (zone binding assay) have been significantly improved. Therefore, present study was designed to investigate the effects of oral administration of cereal grain and seeds on reproductive performance of local cocks. During a period of 63 weeks, 100 local (Iraqi breed) rooster chicks were randomly divided into the five groups (n=20). Animals in group 1 served as control group and had not received any supplementations in their diet. The animals in the Groups 2-5 received diets which were fortified with 100, 200, 300, and 400 g of cereal grain and legume seeds pure germs. The results of the current study showed that the total number of spermatozoa and percentages of abnormal sperm were decreased by adding more amount of germ of cereal grain and seeds (P<0.01). Increased germ of cereal grain and seeds was not associated with pH volume, colour, consistency and motility of the sperm compared to corresponding rates in control group. Phospholipids content and thiobarbituric acid reactive substance of semen sample as well as density of ejaculate (sperm/µl) were decreased by adding increasing germ of cereal grain and seeds in diet of rosters. Weight of testis decreased by increasing levels of cereal grains and legume seeds germ in the diets (P<0.05).
