摘要

本试验旨在研究陈玉米饲粮中添加茶多酚(TP)、维生素E和二丁基羟基甲苯(BHT)对肉鸭生长性能和抗氧化功能的影响。选取1日龄雄性北京鸭192只,随机分为4组,每组6个重复,每个重复8只。以储存3年玉米作为能量原料,Ⅰ组(对照组)饲喂基础饲粮(不添加饲料抗氧化剂),Ⅱ、Ⅲ、Ⅳ组分别饲喂在基础饲粮中添加120 mg/kg TP、维生素E和BHT的试验饲粮。试验期42 d。结果表明:1)与对照组相比,TP能显著提高22~42日龄肉鸭平均日增重(P<0.05),维生素E能显著提高1~21日龄和22~42日龄肉鸭平均日增重(P<0.05),BHT对肉鸭生长性能无显著影响(P>0.05)。2)与对照组相比,TP能显著提高21和42日龄血清总抗氧化能力(T-AOC)以及42日龄血清过氧化氢酶(CAT)活性(P<0.05),维生素E能显著提高42日龄血清CAT活性(P<0.05);BHT能显著提高21日龄血清T-AOC以及21和42日龄血清CAT活性(P<0.05)。由此可见,陈玉米饲粮中添加TP和维生素E对肉鸭生长性能以及抗氧化功能均有不同程度的改善,而BHT只改善了肉鸭的抗氧化功能。陈玉米饲粮中添加TP效果最好。

Abstract

The present study was conducted to investigate the effects of aging corn diet supplemented with tea polyphenol (TP), vitamin E and butylated hydroxytoluene (BHT) on growth performance and antioxidant function of meat ducks. A total of 192 one-day-old male ducks were randomly divided into 4 groups with 6 replicates per group and 8 ducks per replicate. Corn stored for 3 years was utilized to formulate appropriate basal diets. Ducks in the group Ⅰ (control group) were fed the basal diet without antioxidant, and the others in groups Ⅱ, Ⅲ and Ⅳ were fed the basal diet supplemented with 120 mg/kg TP, vitamin E and BHT, respectively. This experiment lasted for 42 days. The results showed as follows: 1) compared with the control group, TP significantly increased average daily gain (ADG) at 22 to 42 days of age (P<0.05), vitamin E significantly increased ADG at 1 to 21 days of age and 22 to 42 days of age (P<0.05), BHT had no significant effect on growth performance (P>0.05). 2) Compared with the control group, TP significantly increased total antioxidant capacity (T-AOC) at 21 and 42 days of age and catalase (CAT) activity at 42 days of age in serum (P<0.05), vitamin E significantly increased CAT activity at 42 days of age in serum (P<0.05), BHT significantly increased T-AOC at 21 days of age and CAT activity at 21 and 42 days of age in serum (P<0.05). In conclusion, aging corn diet supplemented with TP and vitamin E can improve growth performance and antioxidant function of meat ducks, aging corn diet supplemented with BHT only can improve antioxidant function of meat ducks. Aging corn diet supplemented with TP has the best effect.
