摘　　要：旨在探讨不同养殖模式及季节性因素对肉鸡生长性能、屠宰性能及肉品质的影响。选取2个批次的相同品种肉雏鸡,第1批饲养时间为10—12月,第2批饲养时间为3—5月,从第5周龄开始,将每个批次的肉鸡随机分为3组,各组饲养模式分别为散养、网上平养、发酵床养殖。测定并比较相同批次内不同养殖方式与相同养殖方式下不同批次5~10周龄肉鸡的生长性能,以及10周龄后肉鸡的屠宰性能和肉品质性能指标。结果表明:第1批散养肉鸡的第10周龄体重极显著高于发酵床养殖(P<0.01),第2批散养肉鸡的第10周龄体重极显著高于发酵床养殖和网上平养(P<0.01);第1批散养肉鸡的胸肌肉色和粗脂肪含量极显著高于发酵床养殖和网上平养(P<0.01),第2批散养肉鸡的胸肌粗脂肪含量极显著高于发酵床养殖和网上平养(P<0.01);第2批散养肉鸡的腿肌水分极显著低于发酵床养殖和网上平养(P<0.01),腿肌粗脂肪含量极显著高于发酵床养殖和网上平养(P<0.01)。3种饲养模式下,第2批肉鸡的第8~10周龄体重均极显著高于第1批(P<0.01);网上平养模式下,第1批肉鸡的屠宰率与全净膛率显著高于第2批(P<0.05);网上平养与散养模式下,第1批肉鸡的胸肌率极显著高于第2批(P<0.01);3种饲养模式下,第2批肉鸡的胸肌粗蛋白含量极显著高于第1批(P<0.01),第1批肉鸡的腿肌肉色、剪切力与系水力极显著高于第2批(P<0.01)。综上提示,散养模式下肉鸡的体重及肉品质指标优于网上平养及发酵床养殖模式;肉鸡的生产性能、屠宰性能及肉品质受季节性因素影响。The present study was designed to evaluate the influence of different rearing modes and seasonal factors on growth performance,slaughter traits and meat quality of broilers.Two batches of broiler chicks with the same variety were included in this study;the first batch was reared from October to December and the second one was reared from March to May;starting from 5-week-old,the broiler chicks within each batch were randomly allocated into three groups which were reared under three different rearing modes viz.scattered rearing mode,net rearing mode and fermentation bed rearing mode,respectively.The growth performance of broilers was determined weekly from 5-to 10-week-old,and the slaughter traits and meat quality were determined after 10-week-old.The evaluation indexes of the broilers reared under different rearing modes within the same batch and reared in different seasons(batches)under the same rearing mode were statistically compared,respectively.The results showed that in the first batch,the 10-week-old weight of the broilers under scattered rearing mode was extremely significantly higher than that under fermentation bed rearing mode(P<0.01),and in the second batch,the 10-week-old weight of the broilers under scattered rearing mode was extremely significantly higher than that under the other two rearing modes(P<0.01);in the first batch,the meat color and crude fat content of breast muscle of the broilers under scattered rearing mode was extremely significantly higher than that under the other two rearing modes(P<0.01),and in the second batch,the crude fat content of breast muscle of the broilers under scattered rearing mode was extremely significantly higher than that under the other two rearing modes(P<0.01);in the second batch,the broilers under scattered rearing mode had extremely significantly lower moisture content of leg muscle compared to those under the other two rearing modes(P<0.01),and had extremely significantly higher crude fat content of leg muscle compared to those under the other two rearing m
