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.

摘要

本研究旨在确定卵内白藜芦醇 (RV)（Trans.3、4、5-三羟基芪）注射液对 Cobb 雏鸡生产性能、胴体重量和血液成分的影响。将300枚受精肉种鸡种蛋分为5个处理，每组60枚，6个重复，每组10枚蛋。分组如下：(1) 阴性对照（无添加剂），(2) 阳性对照（生理盐水注射），(3) 1.5 mg RV，4) 3.0 mg RV，和 (5) 4.5 mg in ovo房车注射。每天消耗的草料量和处理组之间的饲料转化率发生了显着变化。RV 注射显着改变了血浆中完整脂质谱的参数，包括总胆固醇、甘油三酯、低密度脂蛋白和极低密度脂蛋白。RV 注射显着影响血液生化参数，包括肉鸡血浆中的总蛋白、白蛋白和球蛋白。将 RV 卵注射到肉鸡体内会影响肝肾功能。抗氧化酶在 RV 注射后也发生了显着变化。此外，在 RV 鸡蛋注射中，肉鸡的免疫原性（IgG 和 IgM）发生了显着改变。总之，卵内注射RV显着改善了Cobb肉鸡的肝肾功能、抗氧化活性和免疫功能。
