Abstract
A survey was conducted to estimate the prevalence of gastrointestinal nematodes in grazing dairy replacement heifers in western Canada. Fecal samples were collected from 566 animals on 34 farms distributed over the three prairie provinces. Fecal egg counts were performed using a modified Wisconsin centrifugation technique. The overall mean farm fecal egg count was 16.0 eggs per gram feces (range 0.7-78.1 epg). Gastrointestinal nematodes were demonstrated on every farm examined, and 93.3% of all individuals tested were positive.
摘要
开展了一项调查，以估计加拿大西部放牧的奶牛后备小母牛胃肠道线虫的流行情况。从分布在三个草原省份的34个农场的566头动物身上采集了粪便样本。使用改良的威斯康星离心技术进行粪便虫卵计数。农场粪便虫卵计数的总体平均水平为每克粪便16.0个虫卵（范围为0.7 - 78.1个虫卵/克）。在所检查的每个农场都发现了胃肠道线虫，所有检测个体中有93.3%呈阳性。
