This study was conducted to investigate the effects of feed additives on weight and histological changes in the small intestine. A total of (350) broiler chicks one –day old (Ross 380) – unsexed were randomly divided into (7) equal dietary treatment groups, as follows: Treatment (T1): Basal diet without any addition (control group) ,Treatment (T2): Basal diet + Garlic 4cc/10L,Treatment(T3):Basal diet + Saccharomyces cervisiae 2.5gm/10L,Treatment (T4): Basal diet + Stpire 2.5cc/10 L, Treatment (T5): Basal diet +B. glucan 8gm/10 kg, Treatment (T6): Basal diet + Levamisole 1gm/kg, Treatment (T6): Basal diet + Levamisole 1gm/kg, Treatment (T7): Basal diet + Neomycin 0.5 gm/L. These additions were presented on the first day of the arrival for 5 days, and on the day of first vaccination for 5 days and at the end of the experiment for 5 days also. These chicks vaccinated with NDV on the day one of age by injection in the neck and re-vaccinated at day 10 of age with Lassota, Body weight was weekly determined the results as following: Chicks feed a diet with (T7) showed improvement in villus height and in the (T3, T4).
