河西绒山羊舍饲养殖试验

Experiment of Shelter Feeding and Reproduction of Hexi Down-producing Goats

在传统放牧条件下的河西绒山羊中进行了季节性舍饲喂养殖试验,结果表明:舍饲组绒山羊成、幼年羯、母山羊体重比放牧组分别增加3.34,3.29和2.9 kg。舍饲组仔畜成活率、繁殖成活率、成畜保活率分别达到98.6%,96%和99.5%,比放牧组分别提高5.3,12,1.5个百分点。舍饲组各年龄段山羊绒产量分别达到436.4,349.7和352 g,比放牧组分别提高32.4%,13.1%和15.6%(P<0.01)。

The Hexi down-producing goats under condition of traditional grazing were used to conduct a seasonally shlter feeding and reproduction experiment . The results showed that the body weight of adult, young wether and female down-producing goats in shelter feeding group increased 3.34,3.29 and 2.9kg than that of grazing group, respectively. The survival rate of lamb, the survival rate of reproduction and the reserved rate of adult goats in shelter feeding group were 98.6% ,96% and 99.5% which increased 5.3, 12 and 1.5 perclntage points than those of grazing group, respectively. The down production of down-producing goats of different agl in shelfer feeding group were 436.4,349.7 and 352g which increased 32.4%, 13.1% and 15.6% than that of grazing group,respectively （P 〈 0.01）.
