Abstract

Abstract: This research aimed to determine the impact of in ovo resveratrol (RV) (Trans.3, 4, 5-trihydroxystilbene) injection on performance, carcass weights, and blood constituents in Cobb chicks. A total of 300 fertile broiler breeder eggs were divided into five treatments as 60 eggs in each group, with 6 replicates (10 eggs each). The groups were as follows: (1) negative control (without additive), (2) positive control (saline injection), (3) 1.5 mg RV, 4) 3.0 mg RV, and (5) 4.5 mg in ovo RV injections. Significant changes were found in the amount of forage consumed per day, and the feed conversion ratio between treatment groups. RV injection significantly altered the parameters of the complete lipid profile, including total cholesterol, triglycerides, low-density lipoproteins, and very low-density lipoproteins, in plasma. RV injection significantly affected blood biochemical parameters, including total protein, albumin, and globulin in broiler chicken plasma. Liver and kidney functions were influenced by the injection of RV eggs into broiler chickens. The antioxidant enzymes also changed significantly after RV injection. Moreover, in egg injection from RV the immunogenicity (IgG and IgM) in broiler chickens were significantly altered. In conclusion, in ovo injection with RV significantly improved liver and kidney functions, antioxidant activity, and immune function in Cobb broilers.
