转高赖氨酸基因稻谷替代玉米对肉鸡生产、屠宰性能的影响

Effects of high-lysine transgenic paddy as replacement of corn on production,slaughtering performance of broiler

试验采用不同比例(40%、100%)的转高赖氨酸基因稻谷替代玉米饲喂AA肉鸡,以研究转高赖氨酸基因稻谷替代玉米的效果及可行性。结果表明:21日龄,40%组平均体增重比对照组显著提高6.86%;40%组和100%组的料肉比比对照组分别低7.3%和10.1%;试验组与对照组的胸肌率差异显著,但两试验组之间差异不显著,40%组、100%组分别比对照组显著提高20.9%和14.4%;全净膛率、腿肌率和腹脂率均差异不显著。42日龄,40%组和100%组与对照组的平均体增重均差异不显著,但两试验组之间差异显著,100%组的平均体增重比40%组提高12.8%;料肉比相当;胸肌率三组间差异显著,40%组、100%组分别比对照组显著提高11.4%和22.5%,100%组比40%组显著提高10.0%;40%组腿肌率比对照组显著提高12.5%,而100%组与40%组和对照组均差异不显著;40%组的腹脂率比100%组、对照组分别显著提高38.6%和30.8%,全净膛重、全净膛率差异不显著。试验得出,用40%和100%转高赖氨酸基因稻谷替代玉米饲喂肉仔鸡无不良影响。

AA Broilers were fed with different proportion of high-lysine transgenic paddy as replacement of corn and to investigate the effects of production , slaughtering performance . The results showed that ： 21 d , the average body weight gain of 40% group was significantly improved than the control group by 6.86%, the units consumption of 40% and 100% group were lower than the control group by 7.3% and 10.1%. The respectively breast of 40% and 100% group were significantly increased than the control group by 20.9% and 14.4%. 42 d , The body weight gain of 100% group was significantly increased than the 40% group by 12.8% . There were no significant in units consumption . 40% and 100% group respectively compared with the control group was significantly increased by 11.4% and 22.5%, 100% group than 40% group was significantly increased by 10.0% . The thigh of 40% group was significantly increased than the control group by 12.5%. Abdominal fat, 40% Group was significantly increased than 100% group and the control group by 38.6% and 30.8%. The conclution showed that the high-lysine transgenic paddy had no safty problems used in the broiler diet.
