半散养雄性林麝0～12月龄的生长发育规律研究

Study on the Growth and Development Law of Semi-Free Male Musk Deer from Birth to 12 Months Old

对10头0～12月龄半散养雄性林麝的体重和体尺进行测定，分析了其生长发育规律。结果表明，林麝体重累积生长曲线上升由急剧到平缓。0～4月龄和10～12月龄绝对生长速度呈现明显的上升状态，绝对增重在1月龄达到最大，此后逐渐减慢；0～3月龄生长强度最大，3～6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6月龄前增长明显，6～12月龄增长趋缓，6～12月龄肩高变化不大。该研究揭示了半散养林麝的生长发育规律，为进一步进行林麝选育和半散养生产管理提供参考。

In order to study the growth and development law of the musk deer, the body weight and size of 10 semi-free male musk deer from 0 to 12 months were measured. The results showed that the weight cumulative growth curve increased from intense to gently. The 0-4 and 10 - 12 months absolute growth rate has an increasing trend and the absolute growth peak was between 0 tol 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 - 6 months has a significant lin- ear downtrend, which increases slowly after the age of 8 months. The increase of the body ruler index was significant before the age of 6 months and a downtrend existed between 6 to 12 months. The length and shoulder height of 8 - 12 months changed fewer. The results revealed the growth development law of musk deer, which can provide reference for breeding and semi-free management in the future.
