The effects of anthelmintic treatment on the milk production of cows subjected to contrasting nutritional conditions before and after calving were determined. Half of the cows in each of 2 management treatments were treated with 3.75 grams of fenbendazole on the second day after calving and twice more at weekly intervals. Treated and control cows were grazed together for the entire lactation. Treated cows produced 8% more (P less than 0.05) milk over the 20 weeks lactation than the untreated cows. One third of the total lactation response to anthelmintic treatment occurred during weeks 5 to 10 of lactation. The observed responses occurred despite equal larval challenge to treated and control cows and therefore the responses obtained are discussed in the context of a reduction in the worm burden.
研究了驱虫治疗对产犊前后营养状况不同的奶牛产奶量的影响。在两种管理方式下，每组奶牛中有一半在产犊后第二天接受3.75克芬苯达唑治疗，并在之后每周重复治疗两次。治疗组和对照组奶牛在整个泌乳期一起放牧。在20周的泌乳期内，治疗组奶牛的产奶量比未治疗组奶牛高出8%（P<0.05）。驱虫治疗对泌乳总量的影响有三分之一发生在泌乳期的第5至10周。尽管治疗组和对照组奶牛受到的幼虫感染相同，但仍观察到了上述反应，因此在蠕虫负荷降低的背景下讨论了所获得的反应。
