The effects of a single treatment at entry with three anthelmintics on rates of weight gain and feed conversion efficiency over a 70 day period were studied in 200 feedlot steers. None of the anthelmintic treatments used appeared to confer any improvement in the above parameters under the conditions of this experiment. The results are discussed in relation to routine anthelmintic treatment in western Canada.
在200头饲养场育肥牛中研究了在入栏时单次使用三种驱虫药对70天期间体重增加率和饲料转化效率的影响。在本实验条件下，所使用的任何驱虫药处理似乎都未使上述参数得到任何改善。结合加拿大西部的常规驱虫处理对结果进行了讨论。
