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 1200g of propionic acid and 200g of ammonium bicarbonate according to mass parts, and add them to the reactor, the temperature is controlled at 80°C, and the stirring speed is 120 revolutions / min. After 4 hours of reaction, 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 were added, and the reaction was continued for 3 hours to obtain a feed antifungal agent product. The above-mentioned product is a liquid with a pH of 5, and the amount directly added to the feed is 400 g / ton feed. After mixing 300g of liquid product and 500g of hulling, the dosage ratio in the feed is 1000g / ton of feed.

Embodiment 2

[0044] Weigh 2500g of propionic acid and 900g of ammonium bicarbonate according to mass parts, and add them to the reactor, the temperature is controlled at 75°C, and the stirring speed is 100 revolutions / min. After the reaction for 4 hours, 600 g of ammonium bicarbonate, 200 g of acetic acid, 400 g of benzoic acid, 200 g of sorbic acid, 400 g of citric acid, and 400 g of ethanol were added, and the reaction was continued for 4 hours to obtain a feed antifungal agent product. The above-mentioned product is a liquid with a pH of 5, and the amount directly added to the feed is 450 g / ton feed. After 350g of liquid products, 100g of white carbon black and 450g of vermiculite are mixed, the dosage ratio in the feed is 1500 / 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 proofeffect, 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 anti-mold agent suitable for single feed, additive premixed feed, concentrated feed, compound feed and concentrate supplement. Background technique [0002] All over the world, grains and feeds have serious mold contamination. Feed mildew can cause its nutrient content to decrease, and animals cannot obtain corresponding nutrients after eating; feed mildew also reduces the palatability of the feed, and the animal’s eating ability is reduced or anorexia; the mold that causes feed mildew can also produce a lot of Mycotoxins can reduce the production capacity of feeder animals, and at worst cause the death of feeders; many mycotoxins have a high residual rate in animals, which not only directly cause poisoning to animals, but also transfer from animals through the food chain In the human body, it will cause harm to the human body. At present, the prevention of mildew in feed is mainly achiev...
