从1994年到1996年进行了一项研究，以比较自然获得的胃肠道（GI）线虫感染（主要是捻转血矛线虫）的88加拉和114小东非（SEA）山羊（做）在亚湿润沿海地区的肯尼亚。每年在交配时、交配后3-4个月、产仔前1-2周和产仔后1-4个月记录活重（LWT）、血细胞压积（PCV）和粪卵数（FEC）。有一个显着增加FEC和PCV下降，哺乳期相比，非哺乳期的围产期。这围产期上升FEC发生在两个品种，但更显着和持久的加拉比在SEA。SEA比Galla更能抵抗胃肠道线虫感染，如在生殖周期的所有采样时间，其FEC显著降低和PCV升高所示，但这种品种差异在哺乳期尤为显著。(C)1998 Elsevier Science B.

A study was carried out from 1994 to 1996 to compare the resistance to naturally acquired gastrointestinal (GI) nematode infections (predominantly Haemonchus contortus) of 88 Galla and 114 Small East African (SEA) goats (does) in the sub-humid coastal region of Kenya. Live weights (LWT), blood packed cell volume (PCV) and faecal egg counts (FEC) were recorded each year at mating, 3-4 months after mating, 1-2 weeks before kidding and 1-4 months after kidding. There was a significant increase in FEC and a decline in PCV in lactating does compared to non-lactating does over the peri-parturient period. This peri-parturient rise in FEC occurred in both breeds but was more marked and persistent in the Galla than in the SEA. The SEA does were more resistant to GI nematode infections than Galla does as shown by their significantly lower FEC and higher PCV at all sampling times over the reproductive cycle, but this breed difference was particularly marked over the lactation period.
