Targeted treatment for mildewed feed

The northeast region continues to rain, and many readers have sent a phone call to the newspaper to report that the phenomenon of mildew caused by high humidity is very common. Mildew reduces the nutritional value of the feed, affects palatability, and more seriously causes feed. The product mycotoxin exceeds the standard, and the lighter of the livestock and poultry affects the growth and development, and the severe poisoning and death, not only causes significant economic losses to the farmers, but also endangers human food safety.

For mildly mildewed feed or raw materials, it can be used together with other feeds after treatment, not as a “main grain” for livestock and poultry; for feeds with severe mildew, it is better to dispose of them because of the high cost of treatment. There are mainly the following treatment methods for moldy feed: Mjq China Feed Industry Information Network - based on feed, serving animal husbandry

Elimination method Applicable to the straw, pellet feed, once the mold changes, directly remove the moldy and deteriorated parts. Mjq China Feed Industry Information Network - based on feed, serving animal husbandry

Washing method suitable for seed feed seed based feed mildew, moldy feed may be first pulverized, poured into a tank, add water, stir 3 to 4 times, changing the water twice daily after stirring, until the soaking water from the tea discoloration It is colorless.

Drying method Suitable for a large amount of straw feed is mainly used for a large amount of straw feed. The method is to first dry the moldy feed in the sun, then ventilate and shake to remove the mold. Mjq China Feed Industry Information Network - based on feed, serving animal husbandry

Heating method Suitable for cake raw materials For baking materials, baking at 150 ° C for 30 minutes, or heating in a microwave oven for 8 to 9 minutes, the aflatoxin can be destroyed by 48% to 61%. Mjq China Feed Industry Information Network - based on feed, serving animal husbandry

The de-emergence method is applied to the corn seed, and the toxin is mainly concentrated in the embryo. Firstly grind the corn into small particles with a diameter of 1.5~4.5 mm, add 5~6 times of water, then stir. The fragments of the embryos float on the water surface due to lightness, remove them or pour them off with water. Once, you can achieve the purpose of detoxification.

Lime water immersion method Applicable to corn, sorghum seed feed is suitable for corn, sorghum and other seed feeds. The method is to first pulverize the large-sized moldy feed such as corn into small particles with a diameter of 1.5 to 5 mm (the sorghum and other grains are small, and may not be pulverized), and then the lime powder after 120 mesh sieve is mixed into the moldy feed at a ratio of 0.8-1%. Then, the material and water mixed with the lime powder are poured into the container at a ratio of 1:2, stirred for 1 minute, left to stand for 5-8 hours, the water is poured out, and continuously rinsed with water for 2 to 3 times, after drying. Can be used. It has been shown that adding 5% of quicklime to moldy feed can remove 90 to 99% of toxins. Mjq China Feed Industry Information Network - based on feed, serving animal husbandry

Ammonia method Suitable for bran feed suitable for bran feed. The method is to use 12.5g of ammonia water per kilogram of feed, stir evenly in the container, and then seal with plastic cloth. The detoxification rate is above 87.5% at room temperature 20 ° C, 7 days; the room temperature is 40 ° C, and the detoxification rate reaches 90 after 5 days. %the above.

The alkaline cooking method is suitable for the seed type feed method. It is mixed according to the ratio of 100 kg of moldy feed plus 3 times of water and 500 g of soda ash (or 1 kg of lime) until the feed is cracked, and then cooled. Rinse with water to remove alkali odor. Mjq China Feed Industry Information Network - based on feed, serving animal husbandry

Adsorption clay and zeolite (the main component of which is aluminosilicate) can not only promote the growth and development of livestock and poultry, but also have a strong adsorption effect. Add 0.5% clay or zeolite to the feed to adsorb the mycotoxin in the feed. . Mjq China Feed Industry Information Network - based on feed, serving animal husbandry

Fermentation method Fermentation with Lactobacillus reduces the toxicity of aflatoxin under the action of an enzyme. Treating the feed in this way not only reduces the toxicity of mycotoxins in the feed, but also increases feed nutrients (bacterial proteins) and improves palatability.

Farmer friends can also choose anti-fungal agents to prevent mildew from feed. There are many types of feed anti-fungal agents, and the most widely used ones are propionic acid and its salts. The anti-mildew effect of propionic acid is superior to its salt, but propionic acid has a corrosive and pungent odor. The anti-corrosion effect of ammonium dipropionate is similar to that of propionic acid, and overcomes the disadvantages of propionic acid having corrosive and pungent odor. In addition to the use of a single type of anti-fungal agent, the current trend of the international use of anti-mold agents is the use of composite anti-fungal agents, which are a combination of a variety of organic acid anti-fungal agents in a certain proportion. This compound anti-mold agent can broaden the spectrum of antibacterial spectrum and enhance the anti-mildew effect.
