摘要:
为掌握福建省内山羊球虫感染情况,分别对20个放牧饲养场的600头份粪样和5个舍饲圈养场的150头份粪样进行山羊球虫的感染率、感染强度以及球虫种类的随机抽样调查。结果显示:放牧饲养场中的6月龄内羔羊组、7~18月龄中大羊组以及种羊组球虫的感染率分别为100%、88.5%、84.0%,平均感染率为90.8%,以6月龄内羔羊组的感染强度最大;三组共检出10种山羊球虫;舍饲圈养场中6月龄内羔羊组、7~18月龄中大羊组以及种羊组球虫的感染率分别为68.0%、50.0%、44.0%,平均感染率为46.0%,三组的感染强度都相对较小,共检出7种山羊球虫。可见舍饲圈养场的球虫感染率、感染强度明显低于放牧饲养场。

Abstract:
To understand the coccidial infection of goat in Fujian province,the infection rate,infection intensity and species of goat coccidium were investigated through 600 fecal samples from 20 grazing farms and 150 fecal samples from 5feeding farms.The results indicated that the infection rates of the 6-month-old lamb group,the 7-18month-old goat group and the breeding goat group in the grazing farms were 100%,88.5% and 84.0%,respectively,and the average rate was 90.8%.The 6-month-old lamb group showed the highest infection intensity,and total 10 species of goat coccidium were detected.On the other hand,the infection rates of the 6-month-old lamb group,the 7-18month-old goat group and the breeding goat group in the feeding farms were 68.0%,50.0% and44.0%,respectively,and the average rate was 46.0%.All of these three groups showed relatively low infection intensity,and total 7species of goat coccidium were detected.This experiment demonstrated that the infection rate and infection intensity of coccidium in the feeding farm were obviously lower than those in the grazing farm,which is important for the prevention and controlling of the goat coccidium.
