Abstract
The study aimed to assess the performance of layers fed diet with fermented garlic powder on egg production, egg quality and income over feed cost. A total of 480 (27 weeks old) Dekalb layers were used in the study. The layers were grouped into 60 with eight layers per group in adjacent pens. Each group served as experimental unit. The treatments consisting of a basal layer diet (BLD) and basal layer diet + fermented garlic powder (BLD + FGP) were randomly assigned to the experimental layers.
Results showed highly significant difference (p<0.01) in terms of egg production, feed conversion ratio and eggs mass in favor of BLD+FGP. While in terms of egg quality FGP had FGP had no significant (p<0.05) effect in egg shells thickness, yolk color and albumen height the same with feed intake. However, for income over feed cost the BLD+FGP tended to be higher compared to BLD. Finally, a longer feeding trial and a metabolism or digestibility trial can be recommended to assess efficiently the feeding value of FGP in layers.
