摘要： 【目的】探究饲粮表观代谢能(apparent metabolizable energy,AME)水平对1~28日龄三穗鸭生长性能、屠宰性能及血浆生化指标的影响,并根据回归模型估算AME需要量。【方法】试验选取336只健康1日龄三穗鸭公鸭,采用单因子完全随机设计将试验鸭平分为6组,每组7个重复,每个重复8只鸭。试验鸭分别饲喂AME为10.92、11.38、11.80、12.26、12.68和13.14 MJ/kg的玉米-豆粕型饲粮,试验期28 d。试验结束后,统计生长性能、屠宰性能,并检测血浆生化指标。【结果】饲粮AME水平显著影响日增重、料重比和腹脂率(P＜0.05),且随着AME水平升高,日增重呈线性和二次曲线升高趋势(P＜0.05),料重比呈线性降低趋势(P＜0.05),腹脂率呈线性升高趋势(P＜0.05);饲粮AME水平对总能量摄入、胸肌率、腿肌率以及肝脏指数、肌胃指数均无显著影响(P＞0.05);饲粮AME水平显著影响血浆谷草转氨酶(AST)活性(P＜0.05),对其他血浆生化指标均无显著影响(P＞0.05)。基于直线-折线回归模型,以料重比、日增重和腹脂率为评价指标估测1~28日龄三穗鸭AME最低需要量分别为11.83、11.42和12.24 MJ/kg。【结论】饲喂11.38 MJ/kg AME饲粮可有效改善1~28日龄三穗鸭日增重和料重比,并降低腹脂率。综合考虑,1~28日龄三穗鸭AME最适需要量为11.42~12.24 MJ/kg。

Abstract: 【Objective】 The aim of this experiment was to investigate the effects of dietary apparent metabolizable energy (AME) level on growth performance,slaughter performance and plasma biochemical indices of Sansui ducks aged 1 to 28 days,and to estimate AME requirement based on regression model.【Method】 A total of 336 healthy one-day-old Sansui male ducks were divided into 6 groups with 7 replicates per group and 8 ducks per replicate.Ducks were fed corn-soybean meal diets with AME of 10.92,11.38,11.80,12.26,12.68 and 13.14 MJ/kg,respectively.The experiment period was 28 days.At the end of the experiment,the production performance,slaughter performance and plasma biochemical indexes were measured.【Result】 Dietary AME level significantly affected daily gain,feed conversion ratio and abdominal fat percentage (P<0.05),and with the increase of AME level,daily gain showed a linear and quadratic trend of increasing (P<0.05),feed conversion ratio showed a linear trend of decreasing (P<0.05),and abdominal fat percentage showed a linear trend of increasing (P<0.05).Dietary AME level had no significant effects on total energy intake,breast muscle percentage,leg muscle percentage,liver index and gizzard index (P＞0.05).Dietary AME level significantly affected plasma aspartate aminotransferase (AST) activity (P<0.05),but had no significant effects on other plasma biochemical indices (P＞0.05). Based on broken-line linear regression,the minimum AME requirements of Sansui duck aged 1 to 28 days for optimal feed conversion ratio,daily gain,and abdominal fat percentage were 11.83,11.42 and 12.24 MJ/kg,respectively.【Conclusion】 Dietary 11.38 MJ/kg AME could effectively improve daily gain,feed conversion ratio,and adbominal fat percentage.The optimal AME requirement of Sansui ducks aged from 1 to 28 days was 11.42 to 12.24 MJ/kg.
