【摘要】：为了研究巨菌草饲养北京鸭的效果,将800只1日龄北京鸭平均分为试验组和对照组进行研究,每组设4个重复。对照组全程饲喂肉鸭全价饲料(简称饲料鸭),试验组从22日龄开始用巨菌草代替40%的饲料饲喂北京鸭饲(简称牧草鸭)。每周末称重,63日龄时屠宰测定饲料鸭和牧草鸭肌肉品质和鸭肉有害物质含量。结果:饲喂巨菌草初期(22~49日龄)牧草鸭体重显著低于饲料鸭(P0.05),而饲喂巨菌草后期(50~63日龄)牧草鸭体重与饲料鸭体重无显著差异(P0.05);饲喂巨菌草能够显著降低肉鸭的脂肪含量;饲料鸭肉和牧草鸭肉内主要有害物质含量均低于食品安全标准,但牧草鸭肉内有害物质含量明显低于饲料鸭。
[Abstract]:In order to study the effect of giant fungus grass on Beijing ducks, 800 1-day-old Beijing ducks were divided into experimental group and control group on average, with 4 repeats in each group. The control group was fed with full price feed (abbreviated as feed duck), and the experimental group was fed with Giant fungus instead of 40% feed (abbreviated as herding duck) from 22 days of age. The muscle quality of feed duck and forage duck and the content of harmful substances in duck meat were measured by slaughtering at 63 days of age. Results: the body weight of forage ducks was significantly lower than that of feed ducks at the early stage of feeding giant fungus grass (22 鈮，
