reared on litter to 3 weeks of age, and from 4-8 weeks reared in batteries, birds fed a diet contain
21.13% crude protein and 2978.58 Kcal ME/ Kg diet and, five treatments were carried out T O
treatments without addition of rice bran, and T 1 ,T 2 treatments where addition of rice bran aqueous
extract to drinking water was at level 0.3, 0.9% respectively and ,T 3 ,T 4 treatments where addition
