摘要
本研究以艾维菌商品代肉鸡为观察对象,观测了川府920和V_(10R-868)复合酶对肉用仔鸡的增重效果。结果提示,川府920对肉鸡有显著的增重效果,母鸡的增重效果优于公鸡,43日龄公母平均重达2.04kg,公鸡体重提高3.94％(P<.05),母鸡体重提高5.64％(P<0.01),饲料转化率提高8.37％,经济效益显著,V_(10R-868)复合酶仅对早期(9日龄以前)肉鸡的增重有一定的作用,饲料转化率略低于对照组,无经济效益。上述两种添加剂对提高4周龄以前公鸡的整齐度都有一定的作用。
The study on the effect of Chuanfu-920 and compound enzyme preparation V10R-868 on broilers’ liveweight was made by means of commerrcial breed of A-vian. The results showed that the effect of Chuanfu920 on broilers’ liveweight was remarkable and the effect on hens’ was better than cocks’,the average liveweight reached 2. 04 kg at the age of 43 days,the cock’ s liveweight was inereased by 3. 94% over the contrast group(P<0. 05),the hen’ s liveweight was increased by 5. 64%(P<0. 01), the feed conversion rate was increased by 8. 37% over the contrast group and the economic benefit was significant. The compound enzyme preparation V10R-868 played a partial role in increasing broiler’ s liveweignt only at the early stage (9 days ago) and the feed conversion rate was lower than that of contrast group. The above two kinds of additives, there was partial effect on the increase of the regularity of cocks of 4 weeks.
