结果显示,广东小耳花猪在375日龄时,体重为78.89 kg。
广东小耳花猪在79.33 kg时屠宰率为72.45%,瘦肉率为40.76%,系水力为90.66%。
结果表明壹号土两广小花猪品系在选育后仍保持优良的肉质特性。

In order to understand the carcass and meat quality traits of Guangdong Small-spotted pig, the body weight and back fat of 70 pigs were measured, and half percent of them were selected for slaughter performance test. The results showed that the body weight of Guangdong Small-spotted pig was 78.89 kg at 375 days old. When the weight reaches 79.33 kg, the slaughter rate of Guangdong Small-spotted pig was 72.45%, lean meat rate was 40.76%, and water power was 90.66%. The results showed that Guangdong Small-spotted pig still maintained the characteristics of good meat quality after breeding.Key words Guangdong Small-spotted pig; strain cultivation; carcass traits; meat quality traits 收稿日期:2020-10-08基金项目:广东省重点领域研发计划项目(2018B020203003);国家重点研发计划(2018YFD0501200);湛江市科技计划项目(2019A01004)作者简介:余海乐(1993-),男,福建福清人,硕士,研究方向为动物遗传育种与繁殖.E-mail:****************通讯作者:曾检华(1979-),男,江西会昌人,高级畜牧师,博士,研究方向为动物遗传育种与繁殖.E-mail:********************广东小耳花猪是列入广东省畜禽遗传资源保护名录的优质地方品种,主要分布于广东省湛江市、茂名市下属各县区,是目前广东粤西地区存栏量最大的优质地方良种猪之一。
