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

Abstract

Abstract Background A study was undertaken to assess the effect of bioactive peptides derived from cottonseed (BPC) supplementation on productive performance, egg quality, and total antioxidant capacity (TAC) of serum and yolk in laying hens. A total of seventy-two 22-week-old Bovans White hens were randomly allocated to 12 cages to have similar cage body weight (1520 ± 5 g). The dietary treatments consist of basal diet (control) and basal diet supplements with 5 g BPC/kg of diet. Recording data initiated after 2 weeks. Results 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). Conclusions The results indicated that addition of BPC to Bovans White hens at peaking period, receiving nutrient adequate diets, could induce favorable influences on egg quality and TAC of egg.
