Evaluation of cottonseed bioactive peptides supplementation on performance, egg quality, and total antioxidant activity of serum in laying hens

Abstract

In the second week, hens fed diets containing BPC had significantly higher egg mass and egg weight (P < 0.05). Final BW was significantly higher in laying hens fed diets containing BPC (P < 0.05). The percentage of egg white protein as one of the highest quality proteins available was significantly higher in laying hens fed diets supplemented with BPC (P < 0.05). Hens fed diets containing BPC had significantly higher TAC compared with control group (P < 0.05).
