Problems solved by technology

Propionic acid has a good anti-mold effect, but it is highly volatile, has a short duration of anti-mold, is highly corrosive to production equipment, and is very harmful to the health of production personnel. In addition, the price of propionic acid is relatively high. It is necessary to increase the amount of feed, which increases the cost of feed; although propionate salts have low volatility, their anti-mold effect is not as good as that of propionic acid

Embodiment 1

[0029] Weigh 1200 g of propionic acid and 200 g of ammonium bicarbonate in parts by mass, and add them into the reactor. The temperature is controlled at 80° C., and the stirring speed is 120 rpm. After reacting for 4 hours, add 100 g of ammonium bicarbonate, 15 g of acetic acid, 20 g of benzoic acid, 15 g of sorbic acid, 20 g of citric acid, and 25 g of ethanol, and continue the reaction for 3 hours to obtain a fungicide product for feed. Above-mentioned product is liquid, and pH value is 5, and the consumption that directly adds in feed is 400g / ton feed. After mixing 300g of liquid product and 500g of rice bran, the dosage ratio in the feed is 1000g / ton of feed.

Abstract

The invention relates to a long-acting low-corrosiveness feed mould inhibitor. The physical and chemical reaction is carried out on propanoic acid and ammonium bicarbonate, and then reaction products are compounded with synergistic agents of acetic acid, benzoic acid, sorbic acid, citric acid and alcohol, and finally a liquid state product or a solid state product is prepared. The feed mould inhibitor can effectively inhibit moulds in feed from growing and breeding and can prevent the generation of mycotoxin if added in the feed. The feed mould inhibitor has the advantages of good mould proof effect, long mould proof time, weak volatileness, little corrosion to equipment, little thrill to production staffs, environmental protection and the like, and the pH value is close to that of the feed.

Description

technical field [0001] The invention relates to the field of feed, in particular to a feed antifungal agent suitable for single feed, additive premixed feed, concentrated feed, compound feed and concentrate supplement. Background technique [0002] All over the world, there is serious mold pollution in grain and feed. Feed mildew can reduce its nutrient content, and animals cannot obtain the corresponding amount of nutrients after eating; feed mildew can also cause feed palatability to decrease, and animals' feed intake decreases or anorexia; molds that cause feed mildew can also produce a large amount of food. Mycotoxins can reduce the production capacity of feeding animals in mild cases, and cause the death of feeding animals in severe cases; many mycotoxins have a high residual rate in animals, which not only cause direct poisoning to animals, but also transfer from animals through the food chain into the human body and cause harm to the human body. At present, the prev...
