عنوان انگلیسی Ps-89: Primary Study of The Effect of Methionine Supplementation on Feather Follicles Creation in The Chicken Embryos
چکیده انگلیسی مقاله Objective: Methionine is one of the most aminoacids inorder to creation and growth of the hair and feather follicles. Materials and Methods: 50 fertile eggs from the broiler breeders (Ross 308) devided into 5 equal groups and passed to the hatching machine. Four first groups were inoculated with 20 mg, 30 mg, 40 mg and 50 mg methionie which was dissolved in 0.5 mg sterile water into the yolk sac on the 4th day of incubation. The 5th group was used as the shame control and inoculated with 0.05 ml sterile water into the yolk sac on the 4th day of incubation. On the 18th day of embryonic life, embryous were removed from the eggs and skin samples were taken from the left side of the skin chest and prepared for histological study after hematoxylin and eosin staining. Results: In the microscopic study, feather follicles were increased in all 4 treatment groups but in the 3rd and 4th groups were significant. Conclusion: The results of this primary study showes that injection of different doses of methionine can increase the number of follicles during embryonic period significantly (p< 0.05).
