养殖模式对霍尔巴羊屠宰性能和肉品质影响的研究

Study on the effects of feeding mode on growth slaughter performance and meat nutrient content of Huo’er ba sheep

文章旨在探讨不同养殖模式对霍尔巴羊屠宰性能和肉品质的影响。试验选取60只体重(11.00±3.00)kg的3月龄霍尔巴羊,随机分为放牧组和舍饲组(每组3个重复,每个重复10只),放牧组采取放牧养殖模式,舍饲组采取舍饲养殖模式。结果表明,舍饲组屠宰率、净肉重、肉骨比、眼肌面积显著高于放牧组(P <0.05),内脏比显著低于放牧组(P <0.05)。舍饲组羊肉中蛋白质含量显著低于放牧组(P <0.05),维生素B6含量显著高于放牧组(P <0.05)。由此可见,舍饲养殖显著提高霍尔巴羊的屠宰性能。

The purpose of this study was to investigate the effects of different feeding modes on the growth slaughter performance and meat nutrients of Huo’er ba sheep.Sixty 3-month-old Huo’er ba sheep(body weight :11.00±3.00 kg)were randomly divided into grazing group and housing feeding group,every group contains 3 replicates,and 10 sheep each. The grazing group sheep were fed by grazing while the other were fed inside the house. The results showed as follows :The slaughter performance results showed that the slaughter rate,net meat weight,meat-bone ratio and eye muscle area in the house feeding group were significantly higher than those in the grazing group,while the viscera-weight ratio was significantly lower(P < 0.05),Compared with grazing group’s meat protein content,the house feeding group’s was significantly lower,while the vitamin B6 content was significantly higher(P < 0.05). In conclusion,the housing feeding mode can significantly improve slaughter performance of Huo’er ba sheep.
