Feed mould inhibitor and preparation method thereof

Abstract

The invention belongs to the field of feed additives and particularly relates to a feed mould inhibitor. The feed mould inhibitor is prepared from the following raw materials in parts by weight: 12-18parts of frangrant ainsliaea herb, 10-20 parts of serrate rabdosia herb, 10-20 parts of radix zanthoxyli, 10-20 parts officinal magnolia bark, 3-8 parts of allium macrostemon, 8-12 parts of yam rhizome, 3-8 parts of radix rubiae, 12-18 parts of geranium wilfordii, 2-6 parts of cantharides, 10-20 parts of polygonum aviculare, 8-12 parts of herba chelidonii, 10-20 parts of fruticose breynia juvenile branchlet and leaf, 4-10 parts of compound bacteria, 3-8 parts of compound vitamins and 3-8 parts of compound essential oil. The feed mould inhibitor provided by the invention has the characteristics of small addition amount, cost reduction, safety, reliability, stable quality and no influence on animal palatability; and when being applied to feed mould inhibition, the feed mould inhibitor has good moisture resistance and heat resistance, has less influence of pH value and has the effects of efficiently inhibiting and killing microorganisms such as bacteria and fungi in feed.

Description

technical field [0001] The invention belongs to the field of feed additives, in particular to a feed antifungal agent and a preparation method thereof. Background technique [0002] During the storage, transportation, sale and use of the feed, due to the change of moisture in the feed and the influence of the environment, mildew is extremely prone to occur. Feed mildew and mycotoxin poisoning are common serious problems in livestock and poultry production worldwide, and controlling feed mildew is a link that cannot be ignored in feed production. [0003] At present, commonly used antifungal agents include propionic acid and propionate, sorbic acid and its potassium salt, benzoic acid and its sodium salt, and sodium diacetate. These fungicides play a very important role in protecting feed quality and promoting the healthy development of animal husbandry, and their economic and social benefits have been fully affirmed by people. However, these antifungal agents also have cer...

Problems solved by technology

However, these antifungal agents also have certain problems at the same time, such as propionic acid has pungent odor and strong corrosiveness, large heat loss, fast volatilization, and inconvenient use; and the antifungal effect of sorbic acid and its potassium salt Affected by pH control; benzoic acid and its sodium salt have strict requirements on pH conditions and can only function under acidic conditions, and when the pH value is greater than 4, its anti-mold effect begins to decline, and it will also produce bitter and other bad tastes; As for sodium diacetate, it is added in a large amount. When the complete antibacterial effect is not achieved, sodium diacetate itself, as a nutrient source for microorganisms, promotes the growth of mold. If the amount of sodium diacetate is increased, it can completely inhibit bacteria, but it increases anti-mildew cost

[0004] At present, antifungal and antifungal agents of Chinese herbal medicine have the advantages of wide drug sources, high efficiency, no significant drug resistance, and small toxic and side effects. Therefore, in view of a series of characteristics of Chinese herbal medicines, it is of positive significance to use Chinese herbal medicines in the field of feed mildew prevention, such as application number 201611078554.9 "A Type of Chinese Medicine Antifungal Agent" discloses a traditional Chinese medicine antifungal agent, which is composed of the following formula components in mass fractions: 10-20 parts of Houttuynia cordata, 14-16 parts of Fangfeng extract, 12-14 parts of pine needle extract, 10-10 parts of Shijunzi 12 parts, 13-15 parts of Guanzhong extract, 8-10 parts of Gypsophila extract, 3-5 parts of Nepeta extract, 2-4 parts of artemisinin, and 100-200 parts of distilled water. The research on traditional Chinese medicine preparations has also achieved certain results, but due to the unreasonable formula, the anti-mildew effect of the current traditional Chinese medicine is not very satisfactory, and the mildew of the feed is more serious, which seriously restricts the development of the poultry breeding industry. In view of this It is of great significance to improve the current treatment methods for feed mildew, improve feed quality, reduce feed mildew rate, and effectively promote the healthy development of poultry breeding industry
