Effect of furazolidone on heart weights and myocardial moisture content in turkey poults.

Furazolidone (FZ) at 700 ppm in feed mixtures fed turkey poults from 2 to 5 weeks posthatching significantly increased the ratio of heart weight to body weight (p less than 0.001) and myocardial moisture content (p less than 0.05). The increase in myocardial moisture content is believed to be related to increased glycogen deposition under the influence of FZ since FZ removal from the diet decreased myocardial glycogen levels and moisture content to normal levels.
