摘要
本研究选用刚出壳的绿头野鸭90只,随机分成3组,每组30只,分别饲喂能量相同,蛋白质水平分别为17.00%、19.00%、21.00%的饲粮,通过饲养和代谢试验研究不同蛋白质水平日粮对育雏期(0~4周龄)绿头野鸭生长性能的影响。结果表明,随着饲粮蛋白质水平的提高,蛋白质的代谢率逐渐下降,各组间差异不显著(P>0.05)。从饲料报酬的角度看,19.00%的蛋白质水平完全可以满足绿头野鸭育雏期(0~4周龄)的生长需要。
The experiment was conducted to study the effect of dietary protein level on growth performance of wild Anas Platyrhynchos. Ninety one-day-old ducklings were randomly divided into three groups. The diets had same energy level and different protein level which was 17.00%, 19.00% and 21.00% respectively. The results showed the metabolic rate of protein decreased gradually with raising of protein level,and there was no difference between groups in protein metabolic rate(P〉0.05). 19.00% of protein level met growth requirement of ducklings from the view of feed remuneration.
