Notice: Influencing factors of antifungal agents
There are many factors affecting the antifungal agent, the main ones are microbiological factors and physical and chemical factors. The following takes the feed mildew inhibitor as an example to introduce the influencing factors of the mildew inhibitor in detail.
(1) Microbiological factors: Different types and components of antifungal agents have different pH ranges for printing microorganisms. For example, the suitable pH range of antifungal agents with benzoic acid is 2.5-4.0. After the pH reaches 5.5 or more, it has no effect on many microorganisms. The types of microorganisms in the feed and the degree of contamination they cause are often uncertain, and sometimes some microorganisms will develop resistance, which has a certain impact on the effect of the antifungal agent.
(2) Feed water content: The water in the feed has a great influence on the growth of microorganisms. Experiments have shown that when the water in the feed is 17%-18%, it is most suitable for the reproduction and growth of sanitary clothing. The influence of moisture in the feed on the effect of the antifungal agent is very complex, and the dosage of the antifungal agent should also be adjusted accordingly for feeds with different moisture contents.
(3) Temperature: The temperature suitable for most microorganisms to multiply is 25-30 degrees Celsius. But some special microorganisms, such as Mucor, Rhizopus and other suitable breeding temperature is indeed 25-40 degrees Celsius. Therefore, in the case of different operating temperatures, different dosages of antifungal agents should also be considered.
(4) Feed ingredients: Some feeds containing special ingredients, such as calcium carbonate feed and protein feed, can neutralize the acidic components in the anti-fungal agent and reduce the effect of the anti-fungal agent, so this kind of feed should be more anti-fungal. Dosage of mildew.
