大麻籽粕对狄高肉鸡肉用性能的影响

Effects of Hemp Seed Meal on Slaughtering Performance of Tegel Broilers

选择1日龄狄高肉鸡200羽，随机分5组，A组为对照组，饲喂基础日粮，B、C、D、E组为试验组，分别在玉米-豆粕型日粮基础上添加大麻籽粕部分替换豆粕进行56d饲养试验，研究大麻籽粕对狄高肉鸡产肉性能的影响。结果表明：大麻籽粕可在肉鸡日粮中部分替代豆粕，按0～14日龄4．5％、15～35日龄6%、36～56日龄7％的比例替代豆粕可获得较好的饲料转化效率；添加大麻籽粕有提高狄高肉鸡胸肌率、腿肌率的倾向，屠宰率、全净膛率、半净膛率有降低的趋势，但均未达到显著水平（P〉0．05）。

200 Tegel Broilers at the age of i day were randomly divided into five groups. The group A was control group which fed the basal ration and the group B,C,D,E were treatment groups That were fed the basal ration with Hemp Seed Meal instead of the parts of Soybean Meal. Study Hemp Seed Meal on Slaughter Performance in Tegel Broilers. The results of the test showed that Hemp Seed Meal may be used instead of the parts of Soybean Meal in Tegel Broilers. According to the result of the test, the 4. 5M at the age of 0-14 days,the 6% at the age of 15-35days and the 7% at the age of 36-56days in proportion were better in feed conversion rate; The breast muscle and leg muscle increased, slaughtering index, percentage of eviscerated yield with giblet, percentage of eviscerated yield decreased, but had no remarkable influence（ P〉0. 05）.
