摘要:

本试验旨在研究日粮核黄素水平对1~21日龄北京鸭生长性能、抗氧化能力及激素分泌的影响。本试验采用单因子完全随机试验设计,日粮设8个核黄素水平(1.69、2.39、3.09、3.79、4.49、5.19、8.69、15.69 mg·kg-1);选取体质量相近的1日龄健康的Z7系雄性北京鸭512只,随机分为8组,每组8个重复,每个重复8只鸭。对各生长性能指标进行测定。结果表明,日粮核黄素水平对1~21日龄北京鸭平均日增体质量(ADG)、日采食量(ADFI)、料重比(F/G)均有显著的影响(P<0.05);日粮核黄素水平对21日龄北京鸭血浆及肝脏丙二醛(MDA)、超氧化物歧化酶(SOD)活性有显著的影响(P<0.05);日粮核黄素水平对21日龄北京鸭血浆三碘甲腺原氨酸(T3)、生长激素(GH)有显著的影响(P<0.05)。核黄素对1~21日龄北京鸭生长发育有重要作用。

Abstract:

This experiment was conducted to evaluate the effects of dietary riboflavin levels on growth performance, antioxidant capacity and hormone secretion of Peking ducks from 1 to 21 days of age. Using a one-factor completely randomize design, a total of 512 one-day-old male Peking ducks were randomly divided into 8 groups with 8 replicates in each group and 8 ducks in each replicate. Eight groups were fed eight dietary riboflavin levels (1.69, 2.39, 3.09, 3.79, 4.49, 5.19, 8.69, 15.69 mg·kg-1) diet, respectively. The growth performance were determined. The results showed that dietary riboflavin levels significant affected average daily weight gain, average daily feed intake and feed/gain (P<0.05); dietary riboflavin levels significant affected MDA and SOD in plasma and liver(P<0.05); dietary riboflavin levels significant affected plasma T3 and GH content (P<0.05). Riboflavin was essential for growth of Peking duck from 1 to 21 days of age.
