核黄素缺乏对1~28日龄北京鸭生长性能、器官指数和血浆生化指标的影响
Effects of Riboflavin Deficiency on Growth Performance, Organ Indexes and Plasma Biochemical Indices of Pekin Ducks from 1 to 28 Days of Age
摘要
Abstract
This experiment was conducted to investigate the effects of riboflavin deficiency on growth perform-ance, carcass traits, organ indexes, tissue riboflavin content and plasma biochemical indices of Pekin ducks from 1 to 28 days of age. Using a one-factor completely randomize design, a total of 360 one-day-old male Pe-kin ducks were divided into 3 groups with 12 replicates each group and 10 birds per replicate. The 3 groups were named as riboflavin-deficient group, pair-fed group and ad libitum control group, respectively, the ducks in riboflavin-deficient group were fed a riboflavin-deficient diet ( the measured value of riboflavin content was 1.38 mg/kg) , and the ducks in pair-fed group and ad libitum control group were fed a riboflavin-sufficient diet ( added 10 mg/kg riboflavin to the riboflavin-deficient diet) , and the feed intake of ducks in pair-fed group corresponded with the ducks in riboflavin-deficient group by artificial control. The experiment lasted for 28 days. The results showed as follows:compared with the pair-fed group and ad libitum control group, the aver-age daily gain, breast muscle percentage and leg muscle percentage of ducks were significantly decreased in the riboflavin-deficient group ( P<0.05) , the feed/gain and mortality of ducks were significantly increased in the riboflavin-deficient group (P<0.05), the liver index, heart index and pancreas index of ducks were signifi-cantly increased in the riboflavin-deficient group ( P<0.05) , the contents of plasma riboflavin, liver riboflavin and flavin mononucleotide of ducks were significantly decreased in the riboflavin-deficient group (P<0.05), and the plasma total cholesterol and triglyceride content and aspartate transaminase activity of ducks were signif-icantly increased in the riboflavin-deficient group ( P<0.05) . In conclusion, riboflavin is a essential nutrient for the growth and development of Pekin ducks. Dietary riboflavin deficiency can decrease the growth performance and tissue riboflavin content of Pekin ducks from 1 to 28 days of age, and increase the liver index and plasma total cholesterols and triglyceride contents and aspartate transaminase activity.关键词
