半舍饲与地面平养对京海黄鸡生产性能及肉品质的影响

摘要

本试验旨在研究半舍饲、地面平养对京海黄鸡生产性能及肉品质的影响.选择1日龄京海黄鸡80羽,随机分成2组,每组40羽,分别为半舍饲组和地面平养组,均饲喂统一日粮.结果表明,地面平养可以提高京海黄鸡的生产性能；半舍饲可以极显著降低腹脂率、增加腿肌率(P＜0.01),显著增加肌肉的剪切力(P＜0.05),降低嫩度,具有增加pH、肉色和系水力的趋势.%To investigate the floor rearing with or without outdoor access on growth performance and meat quality of Jinghai yellow chicken. Eighty day-old Jinghai yellow chicken were randomly divided into two groups, the floor rearing with outdoor access and the floor rearing without outdoor access, 40 chicken for each group (20 cocks and 20 hens). The two groups were fed with basal diets. The results showed that the floor rearing without outdoor access could improve growth performance of broilers; the floor rearing with outdoor access could reduce abdominal fat rate and improve leg muscle percentage extremely; the floor rearing with outdoor access could significantly increase shearing force and reduce tenderness , tend to improve pH value, meat color, and water keep ratio.
