Effects of monensin and bambermycins on the performance of market turkeys.
The effects were examined of monensin and the bambermycins in feed on growing turkeys. The drugs were used alone and in combination. A total of 1,600 hen and tom turkeys were divided into 32 pens. Four treatments were used, including 45 or 90 g/ton (907 kg) monensin either to 10 wk of age or to market age with and without adding of 2 g/ton of bambermycins. Evaluation parameters, including body weight, feed efficiency, and mortality, were done at 6, 10, and 13 wk of age for hens and 6, 10, and 18 wk of age for toms. Adding bambermycins increased body weights of hens at 10 wk of age and toms at 6 and 10 wk of age. No differences among treatments were noted at market weight within any of the parameters studied. No differences among treatments were noted in efficiency or mortality by the conclusion of the trial.
