摘　　要：本试验旨在探究限制基础饲粮同时补饲水培大麦苗对籽鹅生长性能、屠宰性能、脏器指数和血清生化指标的影响。选取28日龄籽鹅160只,随机分为4组,每组4个重复,每个重复10只鹅。A组籽鹅自由采食基础饲粮,不补饲水培大麦苗;B、C和D组籽鹅分别以A组采食量的85.0%、72.5%和60.0%饲喂基础饲粮,并自由采食水培大麦苗。试验期42 d。结果显示:1)A和B组籽鹅的总增重和平均日增重显著高于C和D组(P<0.05);B组籽鹅的终末体重显著高于C和D组(P<0.05);B组籽鹅的每千克增重成本最低。2)A和B组籽鹅的腹脂率显著高于D组(P<0.05);A组籽鹅的屠宰率显著高于C和D组(P<0.05),半净膛率和瘦肉率显著高于C组(P<0.05);B组籽鹅的屠宰率和胸肌率显著高于D组(P<0.05),瘦肉率显著高于C和D组(P<0.05)。3)A组籽鹅的肝脏指数显著高于D组(P<0.05),肌胃指数显著低于D组(P<0.05)。4)A和B组籽鹅的血清白蛋白(ALB)含量显著高于C和D组(P<0.05);A组籽鹅的血清谷丙转氨酶(ALT)和肌酸激酶(CK)活性显著高于C和D组(P<0.05),血清葡萄糖(GLU)含量显著高于B和D组(P<0.05),血清总胆红素(TB)含量显著低于C和D组(P<0.05);B组籽鹅的血清甘油三酯(TG)和总蛋白(TP)含量显著高于C和D组(P<0.05)。由此可见,在籽鹅育成期,采取饲喂85.0%基础饲粮并自由采食水培大麦苗的饲喂方案效果较好。This experiment was conducted to explore the effects of restricted basal diet and supplemented with hydroponic barley seedling on growth performance,slaughter traits,viscera indexes and serum biochemical indexes of Zi geese.One hundred and sixty Zi geese at 28 days of age were randomly divided into 4 groups with 4 replicates in each group and 10 geese in each replicate.Geese in group A were provided a basal diet ad libitum without hydroponic barley seedlings.Geese in groups B,C and D were fed 85.0%,72.5%and 60.0%of the basal diet fed in group A,respectively,and hydroponic barley seedlings were provided ad libitum.The experiment lasted for 42 days.The results showed as follows:1)Zi geese in groups A and B had significantly higher total gain(TG)and average daily gain(ADG)than those in groups C and D(P<0.05).Zi geese in group B had significantly higher final body weight(FBW)than that in groups C and D(P<0.05).The cost of weight gain per kilogram in group B was the lowest.2)Zi geese in groups A and B had significantly higher abdominal fat rate than that in group D(P<0.05).Zi geese in group A had significantly higher carcass rate than that in groups C and D(P<0.05),and had significantly higher half net carcass rate and lean meat rate than those in group C(P<0.05).Zi geese in group B had significantly higher carcass rate and chest muscle rate than those in group D(P<0.05),and had significantly higher lean meat rate than that in groups C and D(P<0.05).3)Zi geese in group A had significantly higher liver index and lower gizzard index than those in group D(P<0.05).4)The serum albumin(ALB)content of Zi geese in groups A and B were significantly higher than those in groups C and D(P<0.05).Zi geese in group A had significantly higher serum alanine transaminase(ALT)and creatine kinase(CK)activities than those in groups C and D(P<0.05),had significantly higher serum glucose(GLU)content than that in groups B and D(P<0.05),and had significantly lower serum total bilirubin(TB)content than that in groups C and D(P<0.05).Zi geese i
