Differential response in cardiomyopathy of chicks and turkeys to furazolidone toxicity

Abstract

Dietary furazolidone (500 ppm or higher) significantly slowed the growth of chicks fed either a conventional or a purified diet and of turkeys fed a conventional diet. Deaths were significantly increased in turkeys fed 500 ppm and in chicks fed 700 ppm in the purified diet. Ratio of heart to body weight was significantly increased by furazolidone in turkeys, but not in chicks. Furazolidone did not induce anemia in either species. Turkeys and chicks differed markedly in cardiac response to toxic levels of furazolidone.
