【摘要】 [目的]为了寻求适应广西乃至我国南方的乳用黄牛品种。[方法]我所从新西兰引进一批娟姗牛。通过对娟姗牛适应性观察及其生产性能测定,取得良好效果。[结果]表明:公、母犊牛平均初生重分别为22.75±2.94 kg和20.99±2.94 kg,6月龄平均体重分别为126.14±19.15 kg和126.17±12.22 kg,一岁牛平均体重分别为272.67±54.27 kg和225.61±27.33 kg,四岁母牛平均体重为443.04±62.78 kg。母牛第一胎305 d平均泌乳量4477.05±635.77 kg(4%标准乳)。[结论]娟姗牛适应高温高湿气候环境条件,具有适应性强、耐粗饲、抗热性能良好、抗病力强、泌乳性能高、乳质浓厚、乳脂率高等特点,是一个适应南方饲养的优良乳用黄牛品种,应加快推广应用。更多还原

【Abstract】 【Objective】In order to gain yellow dairy cattle which are well adapted to Guangxi or southern China ecological condition.【Method】Some Jersey cattle were introduced from New Zealand.The adaptability observation and growth performances were performed to detect the introduction effect.【Result】 The result showed that the birth weights of bull and cow were 22.75±2.94 kg,20.99±2.94 kg respectively.The weights were 126.14±19.15 kg,126.17±12.22 kg at the age of 6 months,respectively.The weights were 272.67±54.27 kg,225.61±27.33kg at the age of 12 months respectively.The average weight of cow at 4 yrs old was 443.04±62.78 kg.The average milk yield at first lactation was 4477.05±635.77 kg(the standard milk containing 4% fat).【Conclusion】Jersey cattle could adapt the tropic climate.It had the characters of well-adapted,resistance roughage,good heat and disease resistance,and producing more milk with high fat content It was suggested that Jersey cattle was an excellent yellow dairy cattle that should be developed quickly.更多还原
