摘要
以大丰麋鹿国家级自然保护区的哺乳期仔麋鹿(Elaphurus davidianus)为研究对象,收集了2017年4-6月期间仔麋鹿体重、体长、头长、肩高、胸围、后足长等生长参数,建立了麋鹿体重的生长曲线以及分析体重与其他参数的相关关系。结果表明:哺乳期仔麋鹿体重增长符合logistic增长曲线,方程为Y=209.95/(1+18.861e-0.015t);体重与体长、胸围、肩高等体尺指标相关性较高,达到极显著水平(P〈0.01),体重与头长和后足长无显著相关性(P〉0.05)。本研究为麋鹿的驯养管理提供了基础数据支持。
The body development data of Milu fawns were recorded in their breast-feeding period in the Dafeng Milu Nature Reserve from May to June of 2017. The grown curve of body weight was simulated,and the correlation between body weight and body length,head length,shoulder height,hindfoot length were analyzed. The results were that a reasonable logistic relationship between body weight and time during lactation was observed with an equation of Y = 209. 95/( 1 + 18. 861 e-0. 015 t),and a high correlation coefficient of k A =-0. 985,k B =-0. 981,and AB = 1. 00. The body weight of the animals were significantly related to their body length,chest circumference,shoulder height( P〈0. 01),but not significantly related to their head length and hindfoot length( P〈0. 05). Our observation might serve as data support for Milu domestication and management.
