摘　　要：旨在通过评价饲粮不同粗蛋白质水平对11~17周龄雌性雉鸡生长性能、氮代谢、营养物质表观代谢率、血清生化指标、肌肉化学成分和屠宰性能的影响,研究11~17周龄雌性雉鸡饲粮粗蛋白质适宜需要量。选取11周龄、初始体重为(539.43±11.97)g的健康雌性雉鸡200只,随机分为5组(每组5个重复,每个重复8只鸡)。采用单因素试验设计,各处理组饲粮粗蛋白质水平依次为15.00%、16.50%、18.00%、19.50%和21.00%,预饲期7 d,正式期49 d。结果表明:1)饲粮粗蛋白质水平显著影响雉鸡的平均日增重和料重比(P<0.05),且CP为15.00%组平均日增重显著低于其它4组(P<0.05),CP为15.00%组的料重比显著高于其它4组(P<0.05)。2)饲粮粗蛋白质水平对雉鸡食入氮、粪氮、沉积氮及氮利用率有显著影响(P<0.05)。CP为19.50%和21.00%组食入氮和粪氮含量显著高于其它3组(P<0.05),CP为15.00%和16.50%组沉积氮的含量显著低于其它3组(P<0.05),CP为15.00%组氮利用率显著低于18.00%和19.50%组(P<0.05)。3)各组间干物质代谢率、粗脂肪代谢率和总能代谢率无显著差异(P>0.05)。4)各组间血清高密度脂蛋白胆固醇含量无显著差异(P>0.05)。CP为15.00%组血清总蛋白含量显著低于18.00%、19.50%和21.00%组(P<0.05),CP为15.00%组血清白蛋白含量显著低于18.00%和19.50%组(P<0.05),CP为15.00%组血清尿素含量显著低于19.50%和21.00%组(P<0.05)。CP为21.00%组血清甘油三酯含量显著低于15.00%和16.50%组(P<0.05),CP为21.00%组血清低密度脂蛋白胆固醇含量显著低于15.00%、16.50%和18.00%组(P<0.05),CP为21.00%组血清总胆固醇含量显著低于其它4组(P<0.05)。5)各组间腿肌的粗蛋白质和粗脂肪含量无显著差异(P>0.05),CP为15.00%组胸肌粗蛋白质含量显著低于18.00%、19.50%和21.00%组(P<0.05),CP为15.00%组胸肌粗脂肪含量显著高于18.00%、19.50%和21.00%组(P<0.05)。6)各组间屠宰性能(除腹脂率)和器官指数均无显著差异(P>0.This experiment was conducted to evaluate the effects of dietary crude protein levels on growth performance,nitrogen metabolism,nutrient apparent metabolic rate,serum biochemical indices,muscle chemical composition and slaughter performance of female pheasant aged 11 to 17 weeks,and to study the optimal dietary crude protein level for female pheasant aged from 11 to 17 weeks.A total of 20011-week-old healthy female pheasants with an initial body weight of(539.43±11.97)g were randomly divided into 5 groups with 5 replicates per group and 8 chickens per replicate.A single-factor experimental design was adopted.Dietary crude protein levels were 15.00%,16.50%,18.00%,19.50% and 21.00%,respectively.The pre-feeding period was 7 days,and the formal period was 49 days.The results showed that:1)Dietary crude protein level significantly affected the average daily gain and feed to gain ratio of pheasant(P<0.05),and the average daily gain in CP 15.00% group was significantly lower than that in the other 4 groups(P<0.05),and the feed to gain ratio in CP 15.00% group was significantly higher than that in the other groups(P<0.05).2)Dietary crude protein level had significant effects on nitrogen intake,fecal nitrogen,nitrogen retention and nitrogen utilization rate of pheasant(P<0.05),The content of nitrogen intake and fecal nitrogen in 19.50% and 21.00% CP groups were significantly higher than those in the other three groups(P<0.05),and the content of deposited nitrogen in 15.00% and 16.50% CP groups was significantly lower than that in the other three groups(P<0.05).The nitrogen utilization rate of 15.00% CP group was significantly lower than that of 18.00% and 19.50% CP groups(P<0.05).3)There were no significant differences in dry matter metabolic rate,ether extract metabolic rate and gross energy metabolic rate among all groups(P>0.05).4)There were no significant differences in high-density lipoprotein cholesterol contents among all groups(P>0.05).The serum total protein content in 15.00% CP group was significantly lower tha
