膨化菜子在肉鸭中的应用研究

摘要

研究分两个试验,分别为试验1,选取240只刚孵出(1日龄)樱桃谷肉鸭,随机分为3个试验组和对照组,每组15只,4个重复. 试验1组添加膨化菜子1.75%,试验2组添加膨化菜子3.5%,试验3组添加膨化菜子7%,对照组饲喂基础日粮. 预饲3d后开始正式试验,以生长性能、血液生化指标为参考指标,分析了膨化菜子作为0~14 d肉鸭饲料资源的饲用价值. 试验1结束后,混养3 d后挑选体重无差异的樱桃谷肉鸭64只,随机分为2个处理组,每组8只,4个重复,预饲3 d后进行正式饲养试验,以生长性能为参考指标,分析了膨化菜子作为21~35日龄肉鸭饲料资源的饲用价值. 结果表明,添加膨化菜子的0~14 d试验鸭的耗料量、料重比均优于对照组(P<0.05),而且随着膨化菜子添加比例的增加,增重、耗料均增加、料重比下降(P<0.05). 18~35日龄生长阶段,添加膨化菜子组的料重比也优于对照组. 膨化菜子组ALP水平、氧化指标明显高于其他两个试验组(P<0.05). 结果表明,膨化菜子可以作为一种优质的高能蛋白饲料来配制快大型肉鸭日粮.%Studies in two trials, one for the trial were selected 240 day old Cherry Valley Ducks were randomly divided into four treatment groups, each handle four replicates of 15. Treatment 1 was the control group, two groups add puffed 1.75%rapeseed,rapeseed puffed three groups added 3.5%,4 add puffed rapeseed 7%,3 days after the official pre-feeding feeding tri-als to growth performance, blood biochemical parameters reference indicators analyzed puffing rapeseed as feed resources 0-14 d duck feeding value. After the test an end,after the selection of polyculture 3 day no difference in body weight CherryValley Duck 64, were randomly divided into two treatment groups, each handle four replicates of 8, three days after the official pre-feeding feeding trials to the growth performance of the reference index, analyze puffing rapeseed as feed resources 21-35 days old duck feeding value. The results showed that the addition of feed consumption 0-14 days old test duck puffing rape-seed, feed conversion ratio than the control group (P<0.05), and with the increase in the proportion puffed rapeseed add weight gain, feed consumption were increased,feed conversion ratio decreased (P<0.05). 18-35d growth stage, add the feed to gain ratio also puffed rapeseed group than the control group. Expanded rapeseed group ALP levels, oxidative index was significantly higher than the two other groups (P<0.05).The results showed that puffed rapeseed can be used as a high-quali-ty protein feed for the preparation of high-energy fast large duck diets.
