摘要

A study was conducted to assess the effectiveness (fecal egg count reductions) and benefit (improvement in feed efficiency, average daily gain, health, and so forth) of a macrocyclic lactone (moxidectin [Cydectin Injectable] or doramectin [Dectomax 1% Injectable]) alone or in combination with a benzimidazole (oxfendazole [Synanthic Bovine Dewormer]) as used in steers upon their arrival at a feedlot. The cattle were kept in the feedlot for 181 days. Only minor differences in fecal egg count reductions were seen among treatments, with all egg counts reduced by more than 98% by 28 days posttreatment. Likewise, no statistically significant differences among treatments were seen in terms of animal performance (feed efficiency, intake, gain, morbidity, mortality, and carcass quality). All three treatment regimens appear to be comparable in decreasing nematode burdens and the consequences thereof in feedlot cattle.
