Abstract
The study was conducted to determine the effects of diet with bioactive peptide (add on) with the recommended inclusion level of 0.5% of layer diet by the manufacturer on egg production performance, egg quality and income over feed cost of layers. A total of 433 Dekalb layers (54 weeks old) were used in the feeding trial. The layers were ramdomly allocated to treatments, namely: diet without bioactive peptide A (control) and diet with bioactive peptide. Each treatment had 15 replications with 16 birds per replicate. Results of the study indicated that egg production was numerically improved with the feeding of diet with bioactive peptide. An indication for improvement in feed conversion of layers was also observed with the feeding of diet with bioactive peptide. Egg quality parameters were not influenced by feeding diet with bioactive peptides. Income over feed cost was numerically increased by 4.12% in feeding diet with bioactive peptide.
