| Abstract: | An experiment was conducted with 34-week old layers to study the effect of excessive Zn,Se and I supplementation on performance of the layers.During the experimental period of 4 weeks,Egg production,egg size and feed consumption were recorded.Indexes of egg quality were measured.The results showed that laying performance were not significant affect in Group 1,2 by the treatments.Laying performance was obviously decreased in group 3(P<0 05) and qualities of eggs were not different in all groups. |
