Effect of garlic and vitamin E-selenium on the histologicalpicture of duodenum, liver and bursa of fabricius of broiler

Feeding makes up the major cost of production and good nutrition is reflected in the bird sperformance and its products. The present research has been designed to study the effect ofgarlic with vitamin E-selenium and vitamin E-selenium on the histological picture of duodenum,liver and bursa of fabricius of broiler chickens. Sixty (60) broiler chick of commercial strain(Ross 308) divided into three groups with twenty (20) chicks for each group. In present study, itwas found that the garlic with vitamin E-selenium was effective on the immunity of bursa offabricius which led to increase in lymphocytes. There was a significant increase (P≤0.05) in thediameter of follicles of bursa of fabricius, while the vitamin E-selenium significant (P≤0.05)increase the activity of duodenum and liver which increase in the villi height of duodenum.However there was a significant decrease (P≤0.05) in the epithelial thickness of these villi withcrypt depth of the submucosa of duodenum lead to increase the surface area of the duodenumand decrease the distance between the absorbed material and the villi. Otherwise there was nostrong effect of garlic with vitamin E-selenium on the duodenum and liver.
