Abstract
The effect of different dietary levels of vitamin A (deficient, recomm ended and excess) on weight gain, development of lymphoid organs, hema tological values, humoral response to NDV, cellular response to tuberc ulin and phagocytic activity of neutrophils of broiler chickens was st udied. Vitamin A supplementation 20,000 IU/kg feed (excess level) had beneficial effects on all parameters studied except hematological valu es as compared to deficient and recommended levels.
