Abstract

模拟黄腹角雉野外生存环境和自然种群结构， 采用较大空间散放与多个体群养相结合的方法进行饲养试验， 其笼养繁殖性能比对照组传统对养方式显著提高，通过两年来的试验研究， 结果表明： 试验组平均产卵量为8.5 枚， 卵受精率为82.6% ， 受精卵孵化率为88.7% ； 对照组平均产卵量5.7 枚， 卵受精率50.3%， 受 精卵孵化率 72.4%， 试验组明显高于对照组 ，同时对两组间的卵重、卵形、产卵期进行了测定，无显著差异。

English Abstract

The experiment has been taken through large captive breeding fence with multi individuals group of bird based on the simulation of nature habitat,behavior and population structure of Tragopan caboti. The captive reproductive effect of the experiment groups significantly increased compared with control groups raised in traditional pair breeding method. Through two complete reproductive cycles experiment, the results showed that the average egg laying of the experiment groups was 8.5, fertilization percentage was 82.6%, and incubation percentage of fertilized eggs was 88.7%. The relative index of the control groups was 5.7, 50.3%and 72.4%respectively. The referring indexes of the experiment groups were obviously higher than the control groups. There was no significant difference on the egg weight, egg shape and egg laying period between the experimental groups and control groups.
