目的:该研究的目的是评估水剥夺对Nguni胃肠道线虫负担的影响。
方法:对缺水(n=143)和全年可用(n=142)的家庭中的山羊饲养者进行了一项调查。在一个受控实验中,采食量(ADFI),身体状况评分(BCS),FAMACHA得分,在没有水的情况下确定24和48小时的细胞堆积体积(PCV)和粪便卵数(FEC)。
结果:山羊喝水的频率与距水源的距离之间存在显着关联。从实验中,缺水期的增加降低了ADFI,BCS和PCV,并增加了Nguni山羊的FAMACHA评分和粪便卵数。断水48h山羊的BCS比对照低12%(p<0.05)。
结论:减少供水会增加胃肠道负担,这可能会损害他们的生产力和生产效率。将山羊停水24小时对胃肠道线虫(GIN)负荷没有显着影响。48小时的剥夺期确实增加了GIN负担。
OBJECTIVE: The objective of the study was to assess the effects of water deprivation on the burden of gastrointestinal nematodes in Nguni does.
METHODS: A survey was piloted on goat keepers in households where water was scarce (n = 143) and where it was available throughout the year (n = 142). In a controlled experiment, feed intake (ADFI), body condition score (BCS), FAMACHA score, packed cell volume (PCV) and faecal egg counts (FEC) were determined in does deprived of water for 24 and 48 h.
RESULTS: There was a significant association between the frequency with which goats drink water and the distance from the water source. From the experiment, an increase in the water deprivation period decreased ADFI, BCS and PCV, and increased FAMACHA scores and faecal egg counts in Nguni goats. The BCS of goats deprived of water for 48 h was 12% lower than the control (p < 0.05).
CONCLUSIONS: Reduction in water supply increased gastrointestinal burdens in does, which may compromise their productivity and production efficiency. Depriving goats of water for 24 h had no significant effect on gastrointestinal nematode (GIN) loads. The deprivation period of 48 h increased the GIN burden in does.
