摘要
本研究通过对蛋白、能量和饲料采食量的限饲,探讨商品代AA肉仔鸡(ArberAcres)在35日龄出栏时,限饲对生产性能及其经济效益的影响。试验选用了1日龄AA健康肉仔鸡960只,研究在7～14日龄限饲对35日龄出栏时的生产性能和经济效益的影响。研究结果表明,饲料采食量以限采食量组最低,而体增重、料重比和死淘率最佳值都出现在限采食量组,限蛋白组的效果最差。经济效益分析的结果也表明,限饲料采食组量的效益最好。试验研究表明,肉仔鸡在7～14日龄时限制采食量25%可以提高其生长、生产性能和提高经济效益。因此,在实践生产中可以考虑予以推广采用。
At present study, two experiments were conducted to examine application compensatory growth in practice by restriction of intake, energy or protein in 7～14 days when the slaughtered at 35 day. and economic benefit of Arber Acres broilers were In experiment, 960 1-day AA broilers were used to investigate application and economic benefit of compensatory growth in practice by restriction of energy, protein and intake, in 7-～ 14-day when the broiler were slaughtered at 35-day. The results showed that, the similar results are observed. The greatest or worst performances appear in restriction intake and restriction, individually. Of course, the highest benefit occurs in restriction of intake. According to above mentioned results . it is concluded that the complete compensatory growth is investigated after early restriction intake, and early restriction intake causes higher growth or productive performances and economic benefits compared with control. Therefore, the early restriction （7- ～14-day） may be adopted in practical.
