摘　　要：对从野外采集的１３枚藏雪鸡卵进行种卵品质检测，并采用电孵化机人工孵化。结果测得藏雪鸡卵的平均大小为纵径６２．９±０．５２ｍｍ，横径４３．４±０．０９ｍｍ；试验一组７枚卵（已野外孵化了１７天），卵重平均为５８．８±１．４６ｇ，试验二组６枚卵为６２．８±２．１７ｇ；卵壳厚度平均为０．５５±０．０４ｍｍ，其重量平均为６．７３±０．４６ｇ；雏鸡出壳重量平均为４５．３３±１．５９ｇ。对藏雪鸡卵孵化，温度控制在３７．５－３８℃间，湿度保持在５５％－６４％范围内，整个孵化期卵减重率达２１％，人工孵化率为８３．３％，受精率为９２．３％，孵化期２７ｄ。Tibetan Snow Cock eggs collected from the original habitat were estimatedon the egg qulity and hatched artificially by using electric incubator. The average longitudinaland horizontal diameters of Tibetan Snow Cock eggs were 6 2.9±0.5 2mm and 4 3.4±0.09mm respectively. For group one, the average weight of 7 eggs,which have been alreadyhatched naturally for l7days,was 58.8± 1. 46g,the average weight of 6 eggs was 62.8±2.17g in group two. The average thickness and weight of the shell for 2 groups were 0. 55±0.04mm and 6.73±0. 46g respectively. The initial weight of the chicklings was 45. 33±1.59g。The results indicated that the incubation temperature should be controlled to a range between37,3℃ to 38℃,relative humidity held at 55%-64%。During the entire incubation period,thehaching egg weight decreased by 21%. The hatchability and fertility rate obtained from thisexperiment were 83.3%and 92.3%。The incubation period lasted 27 drys.
