中文摘要：
对160头湖北黑头羊0-24月龄的体重、体尺进行测定,分析了湖北黑头羊生长发育规律。结果表明,湖北黑头羊体重累积生长曲线上升平缓,0-8月龄绝对生长速度呈现明显的上升状态,绝对增重在6-8月龄达到最大,此后逐渐减慢;0-3月龄生长强度最大,3-8月龄呈直线下降趋势,8月龄开始变得平缓;各项体尺指标在8月龄前增长明显,8-12月龄增长趋缓,18-24月龄除胸围外,体高、体长、管围变化不大,试验结果揭示了湖北黑头羊的生长发育规律,为进一步进行湖北黑头羊选育和生产提供参考。
英文摘要：
In order to study the growth and development law of Hubei black-head goat, the body weight and size of 160Hubei black-head goats from 0 to 24 months was measured. The results showed that the weight cumulative growth curve of the Hubei black-head goats increases gently. The 0-8 months absolute growth rate has an increasing trend and the absolute growth peak was between 6 to 8 months old, hereafter slowed down gradually. The growth intensity in 0-3 months was higher than that of other months. The growth intensity of 3-8 months has a significant linear downtrend, which increases slowly after the age of 8 months. The increase of the body ruler index was singificant before the age of 8 months and a downtrend existed between 8 to 12 months. The other index of 18-24 months changed less except for chest circumference. The results revealed the growth development law of Hubei black-head goats. This study can provide basic data for in breeding and production in the future.
