Abstract

The invention discloses a combined antifungal agent with acidizing effect on feed, as well as a preparation method and application thereof. The combined antifungal agent comprises the following components in parts by weight: 20 to 30 parts of propionic acid-ammonium propionate mixture; 0 to 10 parts of sorbic acid; 0 to 5 parts of dehydroacetic acid; 15 to 25 parts of lactic acid; 0 to 5 parts of anhydrous citric acid; 0 to 5 parts of malic acid; 1 to 10 parts of fumaric acid; 5 to 10 parts of phosphoric acid; 1 to 5 parts of an emulgator; 30 to 40 parts of a carrier. The combined antifungal agent with acidizing effect on feed can not only weaken the irritation to the antifungal agent, but also give full play to the synergistic interaction among all components, reduce the dosage of components of the antifungal agent, meanwhile solves the problems of mold prevention and acidification of the feed, and has positive significance for guaranteeing food safety; in addition, the preparation method is low in production cost, simple in technology, safe and high in operability, and does not cause any environmental pollution.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a preparation method and application of a compound antifungal agent with an acidifying effect on feed. Background technique [0002] With the development of the feed industry, the feed is inevitably polluted by mold during storage and circulation. Crops can be infected with mold in the field, harvest, processing, and storage processes. The nutritional value of the feed is reduced and the mold is produced due to the mildew of the feed. Toxins bring great harm to feed safety and seriously threaten human food safety. In order to prevent the feed from becoming moldy, the easiest, most economical and most effective method is to add anti-fungal agents to the feed to inhibit the growth of mold. [0003] During the feeding process of livestock and poultry, due to the immature development of the digestive system of young animals, the secretion of gastric acid is insufficient, the ...
