Influence of monensin and salinomycin on the performance of broiler chicks.
Because monensin and salinomycin are widely used to control coccidiosis, two experiments were conducted to compare the performance of broiler chicks when these compounds were added to the diet. Five levels of each coccidiostat were fed. Increasing the levels of coccidiostat resulted in a decrease in body weight and feed intake. Monensin gave a greater depression at the level suggested by the manufacturer for prevention of coccidiosis (121 ppm) than did salinomycin (66 ppm). The interaction of experiment x treatment was significant and was a result of the greater performance depression at the lower levels (manufacturers' recommended levels) of coccidiostat administered in the first experiment than in the second. This research points out the necessity of the accurate use of the coccidiostats.
