| 摘 要： | 采用粪便检查法、幼虫培养法和蠕虫学剖检法对黑龙江省松花江地区羊胃肠道线虫虫卵排出与成虫寄生的季节动态进行了研究。结果表明，成年羊胃肠道线虫的虫卵排出量和成虫寄生量于5月出现一次明显的春季高潮，8月又出现一次较小的高峰，而一年的其他时期，虫卵排出量和成虫寄生量很低。羊胃肠道线虫的优势虫种是捻转血矛线虫、哥伦比亚食道口线虫、羊仰口线虫、毛圆线虫和毛首线虫。羔羊粪便中最早检获虫卵的时间是6月下旬，一年内虫卵排出量只在7月下旬出现一次高峰。研究结果对控制黑龙江省羊消化道线虫病有十分重要的意义。

| Abstract: | Seasonal incidence of egg output and adult worm burden of gastro-intestinal nematodes in sheep in Songhuajiang area in Heilongjiang Province was observed by fecal examination, larval culture and helminthological examination. The first peak and the second peak of egg output and worm burden of gastro-intestinal nematodes in adult sheep were in May and August, respectively. The predominant worm species were Haernonchus contortus, Oesophagostornum colurnbianurn, Bunostornum trigonocephalum, Trichostrongylus sp. and Trichuris sp.. The egg was found firstly in lamb feces on pasture in late June, and the peak of egg output appeared in late July. These results had an important implications for the control of nematodes in digestive system of sheep in Heilongjiang Province,China. |
