Performance of turkey poults when fed two levels of methionine with and without ipronidazole.

Two experiments were conducted to determine the effect of adding ipronidazole to the diet of turkey poults containing two different levels of methionine. A corn-soybean meal diet with 0 to .18% supplemental methionine was fed to Nicholas Large White poults from 1 to 21 days of age. The addition of .18% supplemental methionine significantly improved body weight and feed efficiency. The addition of ipronidazole to the diet with either level of methionine did not influence body weight, feed efficiency, or grams of sulfur amino acid required to produce a gram of weight.
