Abstract
The influence of stresses due to transport of beef cattle and their allotment to feedlots on trichostrongylid infection was studied. The greatest increases in worm egg counts and serum pepsinogen levels were seen at 5 h and 30 days after allotment. These apparently resulted from reactivation of arrested larvae which the animals ingested while grazing during late autumn at the breeding farm.
摘要
研究了肉牛运输及分配至饲养场产生的应激对毛圆线虫感染的影响。在分配后的5小时和30天，观察到虫卵计数和血清胃蛋白酶原水平的最大增幅。这些明显是由于动物在深秋于繁殖场放牧期间摄入的滞育幼虫重新激活所致。
