摘　　要：试验旨在探究低豆粕、低蛋白日粮对尼古拉火鸡生长性能的影响。选择1日龄尼古拉火鸡360只,结合体型、性别比例随机分为9组,每组设4个重复,每个重复10只鸡。实验分为0~4周龄以及5~8周龄两个阶段,并使用3×3双因素试验方法,研究常规蛋白质水平日粮(玉米-豆粕型、玉米-低豆粕添加型、糙米-玉米-低豆粕添加型)、蛋白质水平由27%降至25%日粮(玉米-豆粕型、玉米-低豆粕添加型、糙米-玉米-低豆粕添加型)、蛋白质水平由27%降至23%日粮(玉米-豆粕型、玉米-低豆粕添加型、糙米-玉米-低豆粕添加型)对尼古拉火鸡生长性能的影响。结果显示,与常规蛋白质水平、玉米-豆粕型日粮组相比,降低4个百分点蛋白质水平日粮(玉米-豆粕型、玉米-低豆粕添加型、糙米-玉米-低豆粕添加型)火鸡全期增重显著降低(P<0.05),但料重比显著增高(P<0.05),饲料利用率较差。研究表明,尼古拉火鸡日粮的蛋白质水平在0~4周龄阶段由27%降低到25%,5~8周龄阶段由25%降低至23%,火鸡的增重及饲料报酬未受到显著影响,但进一步降低日粮蛋白质水平将会导致火鸡生长性能显著下降。The purpose of the experiment was to investigate the effects of low soybean meal and low protein diet on growth performance of Nicholas turkey.360 one-day-old Nicholas turkey were randomly divided into nine groups with four replicates in each group and 10 turkeys in each replicate.The experiment was divided into two stages:0~4 weeks old and 5~8 weeks old.The effects of conventional protein level diets(corn-soybean meal,corn-low soybean meal,brown rice-corn-low soybean meal),diets with protein levels were reduced from 27%to 25%(corn-soybean meal,corn-low soybean meal,brown rice-corn-low soybean meal)and diets with rprotein levels were reduced from 27%to 23%(cornsoybean meal,corn-low soybean meal and brown rice-corn-low soybean meal)on growth performance of Nicholas turkeys were studied by using 3×3 two-factor test method.The results showed that the whole-period weight gain of turkeys fed with 4%reduced protein level(corn-soybean meal type,corn-low soybean meal type,brown rice-corn-low soybean meal type)decreased significantly(P<0.05),but the feed-to-weight ratio increased significantly(P<0.05),and the feed utilization rate was poor.The study indicates that the dietary protein level of Nicholas turkey decreased from 27%to 25%at 0~4 weeks old and from 25%to 23%at 5~8 weeks old.The weight gain and feed reward of turkeys were not significantly affected,but further reduction of dietary protein level would lead to significant decline in growth performance of turkeys.
