There were significant differences in the prevention effects of methyl salinomycin on the stacking, brucellae, giant and toxic e. coli coccidioides in broiler chickens. Usually, the concentration of 40mg/kg of drug produced good effects on the stacking and giant e. coli coccidioides.To poison e. coli, 60mg/kg drug concentration is required to be effective.To be effective, eimerella brucellae must use a concentration of 80mg/kg.
We can customize according to customer's requirement.
