The possibility of using iodine-chloroxyquinoline (IC) mycostatic agent in fodder was investigated. The anti-bacterial effect of IC is used successfully in the therapy of dyspepsia and diarrhea in man and animals. The mycostatic effect of IC was investigated in a synthetic nutrient (Sabourand agar) and in corn chop in 3 concentrations (100, 200 and 400 mg/kg). The following test microorganisms were used: Alternaria sp., Aspergillus sp., Fusarium sp. and Penicillium sp. IC gave satisfactory results in the synthetic nutrient in the concentrations of 100-400 mg/l of nutrient. During 14 days there was no increase of the investigated moulds. The mycostatic effect of IC in corn chop with 16% moisture, with IC concentration of 200-400 mg/kg was found to be good. In the corn chop with 16% moisture, with IC concentration of 100 mg/kg the effect was unfavourable. Already after 15 days there was an intensive multiplication of moulds of Penicillium and Aspergillus genera. There was no notable increase in the number of moulds in the control sample with 12% moisture, which indicates that such moisture concentration does not give good conditions for the propagation of moulds. IC slowed down the increase in the number of moulds in the samples with 200 and 400 mg/kg, relative to the control sample. Between the 45th and 60th day of the experiment there was an increase in the number of moulds in the corn chop sample with 16% moisture and 200 mg/kg of the mycostatic agent. The authors draw a conclusion from what was stated that the optimum mycostatic effect of IC under such conditions should be expected with the concentration of 300-400 mg/kg.
