Abstract

Fecal samples were examined between 17 September and 1 November 1993 from 1765 cattle (one bull, 533 cows, 474 heifers, 22 steers, and 735 calves) on pasture on 15 farms in 11 counties in Kentucky for eggs or larvae of internal parasites. All of the cattle were beef-type except for 22 which were dairy-type. In fecal samples from the bull, cows, heifers, steers, and calves, the types of helminth eggs present were trichostrongyles (excluding Nematodirus) in 0%, 25%, 31%, 86%, and 93%, Nematodirus in 0%, 0%, < 1%, 0%, and 34%, Strongyloides in 0%, 0%, < 1%, 0%, and 7%, Trichuris in 0%, 0%, 0%, 0%, and 2%, Capillaria in 0%, 0%, 0%, 0%, and < 1%, and Moniezia in 0%, 1%, 8%, 5%, and 21%, respectively. Dictyocaulus viviparus larvae were present in feces of calves (7%) on one farm and heifers (< 1%) on another farm.

摘要

1993年9月17日至11月1日期间，对肯塔基州11个县15个农场牧场的1765头牛（1头公牛、533头母牛、474头小母牛、22头阉牛和735头小牛犊）的粪便样本进行了检查，以查找体内寄生虫的虫卵或幼虫。除22头为奶牛型外，所有牛均为肉牛型。在公牛、母牛、小母牛、阉牛和小牛犊的粪便样本中，发现的蠕虫卵类型分别为：毛圆线虫（不包括细颈线虫），占比分别为0%、25%、31%、86%和93%；细颈线虫，占比分别为0%、0%、<1%、0%和34%；类圆线虫，占比分别为0%、0%、<1%、0%和7%；鞭虫，占比分别为0%、0%、0%、0%和2%；毛细线虫，占比分别为0%、0%、0%、0%和<1%；莫尼茨绦虫，占比分别为0%、1%、8%、5%和21%。在一个农场的小牛犊粪便中（7%）以及另一个农场的小母牛粪便中（<1%）发现了胎生网尾线虫幼虫。
