肉用雏鸡饲料最佳营养水平研究初探

Research on Best Nutrition Level of Chicks

以3×5因子的设计进行试验,主要探讨肉用仔鸡在0-3周龄阶段不同营养水平对日增重的影响,并分析日采食量、日采食能量和饲料报酬,以寻求科学的饲料配方和更高的经济效益.试验结果表明,能量水平为2900Kcal/kg,赖氨酸水平1.44%、蛋+胱氨酸水平1.16%的第10组的日增重效果最好,三周龄的平均日增重为16.30±2.31g.

This experiment is carried out with the formula of 3×5 factors. It is to find out the influence of different nutrient feed to ADG and analysis of intake, energy intake and feed efficiency. The Objective is to seek scientific and higher cost - effectiveness. The results show that 10th group about the energy level 2900Kcal/kg and lysine 1.44% and Met ＋ Cystine 1.16%, is the best group. The average ADG of three weeks is 16.30 ＋ 2.31g.
