河西地区规模化羊场全舍饲条件下绵羊、山羊饲养繁育的研究

Studies on Raising and Breeding of Several Breeds of Sheep and Goats Fed at the Newly built Dimensionized Sheepshed in Hexi Area of Gansu Province

在规模化羊场舍饲条件下，对９个品系的绵羊、山羊的饲养繁育进行了初步的观察和研究，结果表明：全舍饲条件下饲养管理条件得到了很大的改善；夏洛来羊在所研究品种中初生重最大达（４５６±０３０）ｋｇ；３月龄体重达（２２３４±１２５）ｋｇ；从初生到３月龄的生长速度，无角陶赛特表现最快。研究组中山羊出生重最重的是安哥拉山羊，为（２３７±０２５）ｋｇ；对胸围、臀围等体尺进行的测量表明，其中夏洛来为最大，中卫山羊在山羊组中最大；血红蛋白的常规指标测定结果为，蒙古羊和中卫山羊基本表现正常，其他品种则表现较低，白细胞数量在所有品种中表现正常；采食行为中采食时间夏洛来、无角陶塞特、萨福克羊较其他品种短而反刍时间则较长；性成熟时间山羊晚于绵羊，舍饲绵羊、山羊在生产质量方面明显优于放牧羊。

The results show that the conditions of raising and management are improved at newly built sheep shed. Charolais sheep has the heaviest newborn weight with (4 56±0 30)kg among all of the sheep and goats. The 3 month old weight can reach to (22 34±1 25) kg. Poll Dorset sheep shows the most rapid growth rate (0 19±0 14) kg/d from the newborn to 3 month old. Angora goat has the heaviest newborn weight with (2 37±0 25) kg among the goats. Charolais has the largest heart girth and buttocks girth in the sheep, and the largest of Zhongwei goat in the goats. The hemoglobin of Mongolia sheep and Zhongwei goat indicate nearly normal, however ,other breeds show lower. The normal amount of white blood cells can be examined in all the breeds. Charolais, Poll Dorset and Suffolk spend shorter time for taking feed, but need longer for rumination. The sexual mature period of goat is longer than that of sheep. The productive qualities of sheep and goats fed at sheep shed are superior to that of breeds herded on pasture.
