不同育幼方式及出生体重对大熊猫幼仔生长发育的影响
Effects of fostering methods on the growth and development of giant pan-da cubs with different birth weight
摘要
Abstract
In this study,80 giant panda cubs born between 2012 and 2019 were selected to systematically study the ef-fects of birth weight([50,100)g,n=7;[100,150)g,n=25;[150,200)g,n=37;[200,250)g,n=11),fostering meth-od(female feeding,n=12;artificial feeding,n=10;artificial and female alternate feeding,n=58)and fetal litter size(single,n=14,and twins,n=66)on the growth and development of the cubs.We collected the daily gain,milk feeding amount,and eye and ear development during the early development of the cubs(from 0 to 120 days).The results showed that the birth weight of singleton pups was significantly higher than that of twin pups(P＜0.05).We also found that the early growth and development of pups are closely related to their cub-fostering methods and birth weight(R2＞0.973 7).The greater the birth weight of the pups,the greater the growth rate.The lighter the birth weight of the cubs,the lower the shrinkage,but the higher ratio of shrinkage to its birth weight.In addition,the lighter the birth weight of pups,the lower the developmental status of their ears and eyes.In conclusion,our study provides a theoretical basis on the selection of and the improvement of cub-fostering methods for the giant panda.关键词
