摘要

本试验旨在研究核黄素对北京鸭生长性能和抗氧化机能的影响。试验分2阶段,第1阶段(1~21日龄):选取1日龄健康雄性北京鸭128只,按体重一致的原则分为2个处理(核黄素缺乏组和对照组),每个处理8个重复,每个重复8只鸭。核黄素缺乏组饲喂基础饲粮(未添加核黄素),对照组饲喂基础饲粮中添加7 mg/kg核黄素的试验饲粮。第2阶段(22~33日龄):挑选体重接近的采样剩下的核黄素缺乏组试验鸭40只,分为2个处理(核黄素缺乏组和核黄素补充组),每个处理5个重复,每个重复4只鸭。核黄素缺乏组饲喂基础饲粮(未添加核黄素),核黄素补充组饲喂基础饲粮中添加7 mg/kg核黄素的试验饲粮。结果表明,1~21日龄,与对照组相比,核黄素缺乏组显著降低了试验鸭末重、平均日增重、平均日采食量及肝脏和血浆核黄素含量(P<0.05),显著提高血浆丙二醛(MDA)含量(P<0.05);1~21日龄核黄素缺乏组的试验鸭饲粮中补充核黄素后,与核黄素缺乏组相比,核黄素补充组显著提高了22~33日龄试验鸭末重、平均日增重、平均日采食量及肝脏和血浆核黄素含量(P<0.05),显著降低了血浆MDA含量(P<0.05)。由此可见,饲粮中核黄素缺乏可显著降低1~21日龄北京鸭生长性能及血浆抗氧化机能,22~33日龄补充核黄素可显著提高其生长性能,改善血浆抗氧化机能。

Abstract

This experiment was conducted to study the effects of riboflavin on the growth performance and antioxidant capacity of Peking ducks. The experiment was concluded two periods. The first period (1 to 21 days of age): a total of 128 one-day-old male Peking ducks with an average body weight were randomly divided into 2 treatments (riboflavin deficient group and control group) with 8 replicates per treatment and 8 ducks per replicate. The ducks in the riboflavin deficient group were fed a basal diet (without riboflavin) and those in the control group were fed the basal diet supplemented with 7 mg/kg riboflavin. The second period (22 to 33 days of age): forty Peking ducks with an average body weight from the riboflavin deficient group were randomly divided into 2 treatments (riboflavin deficient group and riboflavin supplemented group) with 5 replicates per treatment and 4 ducks per replicate. The ducks in the riboflavin deficient group were fed a basal diet (without riboflavin) and those in the riboflavin supplemented group were fed the basal diet supplemented with 7 mg/kg riboflavin. The results showed that compared with the control group at 1 to 21 days of age, the final body weight, average daily gain (ADG), average daily feed intake (ADFI) and the riboflavin content in liver and plasma in the riboflavin deficient group were significantly decreased (P<0.05), while the plasma malondialdehyde (MDA) content was significantly increased (P<0.05). The ducks in the riboflavin deficient group were supplemented riboflavin at 22 to 33 days of age, compared with the riboflavin deficient group, the final body weight, ADG, ADFI and the riboflavin content in liver and plasma in the riboflavin supplemented group were significantly increased (P<0.05), while the MDA content was significantly decreased (P<0.05). In conclusion, dietary riboflavin deficiency can decrease the growth performance and plasma antioxidant capacity of Peking ducks at 1 to 21 days of age, while supplemented with riboflavin can improve the growth performance and plasma antioxidant capacity of Peking ducks at 22 to 33 days of age.
