How to prepare the dosage of mildew prevention agent under normal circumstances
Anti-mildew agent for feed refers to feed additives that can reduce the number of microorganisms in feed, control the metabolism and growth of microorganisms, inhibit the production of mycotoxin, prevent the loss of nutrients in the storage period of feed, prevent feed moldy deterioration and prolong the storage time. Mildew is widely distributed in nature, and there are many kinds of mildew, and most of the mildew can cause the deterioration of feed, so that the nutritional value of feed is greatly reduced, palatability becomes poor; Serious mildew not only has no nutritional value, but also can cause growth retardation, viscera damage, and even death by poisoning. It is an effective way to prevent feed mildew by using mildew inhibitor in feed.
A.currently commonly used varieties of mildew prevention agent
1.Benzoic acid and sodium benzoate. Benzoic acid and sodium benzoate can non-selectively inhibit the activity of microbial cell respiration enzyme, so that microbial metabolism is affected, so as to effectively inhibit the growth and reproduction of a variety of microorganisms, and have no adverse effects on the growth and reproduction of animals. The main use of sodium benzoate in the feed, the general use of less than 0.1%.
2. Propionic acid and its salts. Propionic acid is a corrosive organic acid, colorless transparent liquid, soluble in water. Propionate includes sodium propionate, calcium propionate, potassium propionate and ammonium propionate. Propionic acid and propionate are acid mildew prevention agents, with a wide antibacterial spectrum, mold, fungi, yeast and so on have a certain inhibitory effect, its toxicity is very low, is the intermediate product of normal metabolism of animals, all kinds of animals can be used, is the most commonly used in feed a mildew prevention agent.
3.Fumaric acid and its esters. Fumarate esters include dimethyl fumarate, diethyl fumarate and dibutyl fumarate, etc., among which dimethyl fumarate has a better anti-mildew effect. Fumaric acid and its esters are also acid mildewproof agents, antibacterial spectrum is wider, and can improve the taste of feed and improve feed utilization, the general use of about 0.2%.
4.Dehydroacetic acid. Dehydroacetic acid is a kind of efficient broad-spectrum antibacterial agent, which has strong inhibitory effect on the development of bacteria, mold and yeast, especially the strongest effect on mold, and has certain antibacterial effect under acid, alkali and other conditions. Dehydroacetic acid is a low toxicity anti-mold agent, generally has no adverse effects, the amount of about 0.05%.
5. Parabens. It has the strongest effect on mold and yeast. The co-existence of p-hydroxybenzoate with starch will affect its effect, so attention should be paid when using it.
6.Compound anti-mold agent. It refers to the combination of two or more different mildew prevention agents. Compound mildew prevention agent has wide antibacterial spectrum, large application range, good mildew prevention effect and small dosage, easy to use. It is a more commonly used mildew prevention agent variety in feed.
