Research note: does compensatory growth occur following withdrawal of salinomycin from the diet of broilers?
Two floor pen studies were conducted to determine whether compensatory growth occurs following withdrawal of the anticoccidial drug salinomycin from the feed of broilers reared to 46 days of age. There were no significant differences in weight gain or feed conversion between medicated and unmedicated birds whether overall performance or performance during the 1-wk withdrawal period was measured. Feed intake of birds given salinomycin, however, was significantly lower than that of unmedicated birds, and feed intake following withdrawal was greater than that of birds still receiving the drug.
