Description

Monensin and salinomycin, which are produced by Streptomyces, are widely used as additives in broiler feed and cattle feed. However, at a certain level, these antibiotics are toxic. For the quality control of feed and premix it is thus very important to monitor the concentrations of these antibiotics. At present, colorimetric methods are widely used for this purpose, but they are rather time-consuming. The present paper describes the application of colorimetric methods to flow injection analysis (FIA) of these antibiotics. The established method facilitates the rapid analysis of feed and premix for the quality checking.
