摘要: 【目的】旨在探究20~22周龄雄性雉鸡适宜代谢能水平,为科学饲养雉鸡、提高生产效率提供数据参考。【方法】选取20周龄、体重相近的健康雄性雉鸡160只,随机分为4组,每组5个重复,每个重复8只鸡,采用单因素试验设计,各组饲粮代谢能水平分别为11.30、11.72、12.14和12.56 MJ/kg,预试期5 d,正试期16 d,测定雉鸡生长性能、屠宰性能和肉品质。【结果】饲粮代谢能水平对雉鸡平均日增重有极显著影响(P<0.01),对雉鸡屠宰率、全净膛率和腿肌率,以及胸肌粗蛋白质含量有显著影响(P<0.05),对雉鸡脏器系数均无显著影响(P>0.05)。11.72和12.14 MJ/kg组雉鸡平均日增重极显著高于11.30 MJ/kg组(P<0.01),显著高于12.56 MJ/kg组(P<0.05);12.56 MJ/kg组雉鸡屠宰率和全净膛率显著高于其余各组(P<0.05);11.72 MJ/kg组腿肌率显著高于11.30和12.14 MJ/kg组(P<0.05);12.14和12.56 MJ/kg组雉鸡胸肌粗蛋白质含量显著高于11.30 MJ/kg组(P<0.05)。以平均日增重为估测指标,经一元二次回归模型分析,得出此时期雄性雉鸡饲粮适宜代谢能水平为11.98 MJ/kg。【结论】在本试验条件下,20~22周龄雄性雉鸡饲粮适宜代谢能水平为11.98~12.56 MJ/kg。

Abstract: 【Objective】 The aim of this study was to explore the appropriate metabolic energy levels of 20-22 weeks old male pheasants,providing data reference for scientific breeding of pheasants and improving production efficiency.【Method】 A total of 160 healthy male pheasants at 20 weeks of age with similar weight were randomly divided into 4 groups,each group was set up with 5 replicates,each replicate was 8 chickens,and the dietary metabolic energy levels of each group were 11.30,11.72,12.14 and 12.56 MJ/kg,respectively,with a pre-trial period of 5 days and a positive trial period of 16 days.The growth performance,slaughter performance,and meat quality of pheasants were measured.【Result】 The level of dietary metabolic energy affected the average daily gain (P<0.01),the slaughter rate,total purification rate and leg muscle rate,and the crude protein content of pectoral muscle (P<0.05),while had no significant effect on the organ index of pheasants (P>0.05).The average daily gain of 11.72 and 12.14 MJ/kg group were higher than that of 11.30 (P<0.01) and 12.56 MJ/kg group (P<0.05).The slaughter rate and total purification rate of pheasants in the 12.56 MJ/kg group were significantly higher than those in the other groups (P<0.05),and the leg muscle rate in the 11.72 MJ/kg group was higher than that in 11.30 and 12.14 MJ/kg group (P<0.05).The crude protein content of pectoral muscle in 12.14 and 12.56 MJ/kg group were higher than that in 11.30 MJ/kg group (P<0.05).Using the average daily gain as the estimation indicator,the optimal metabolic energy level for male pheasants during this period was to be 11.98 MJ/kg through a univariate quadratic regression model analysis.【Conclusion】 In summary,under the conditions of this experiment,the suitable metabolic energy level of male pheasants during 20-22 weeks old was 11.98-12.56 MJ/kg.
