Impact of doramectin treatment at the time of feedlot entry on the productivity of yearling steers with natural nematode infections

Abstract

Under the conditions of our trial, there was a significant fecal egg count reduction response to doramectin treatment, which resulted in significantly improved productivity. Results of economic analysis of return on investment indicated that even with low egg counts in heavy body weight cattle, nematode egg count reduction with doramectin significantly improved returns.
