Embodiment 1

[0021] This example provides a slow-release antifungal agent for feed, which includes the following components in parts by weight: 40 parts of propionic acid, 20 parts of ammonium propionate and 50 parts of carrier, and the molar ratio of propionic acid and ammonium propionate is 1:0.41. Ammonium propionate is purchased or synthesized from propionic acid and ammonia. Ammonia is one or more mixtures of ammonium carbonate, ammonium bicarbonate, ammonia water, and liquid ammonia. In this embodiment, ammonium propionate is preferably prepared from propionic acid and It is synthesized by liquid ammonia reaction. The carrier is one or a mixture of two or more of silicon dioxide, sodium sulfate, zeolite powder, montmorillonite, sepiolite, bentonite and medical stone. In this embodiment, the preferred carrier is silica.

[0022] The present embodiment also provides a preparation method of the above-mentioned slow-release antifungal agent for feed, comprising the following steps:

Abstract

The invention belongs to the technical field of feed additives, and particularly discloses a feed slow-release mildew preventive. The feed slow-release mildew preventive is prepared from the followingcomponents in parts by weight: 20 to 55 parts of propionic acid, 5 to 30 parts of ammonium propionate and 15 to 75 parts of carrier, wherein the molar ratio of the propionic acid to the ammonium propionate is 1 to (0.2-0.6). The invention also provides a use method of the feed slow-release mildew preventive. The feed slow-release mildew preventive is added into feed with the moisture content being less than or equal to 12.5 percent and the humidity being less than or equal to 85 percent, and the adding amount of the feed slow-release mildew preventive in the feed is 400 to 800g / T. The feed slow-release mildew preventive provided by the invention can effectively prevent the propionic acid from being quickly volatilized, cover the irritation of the propionic acid and guarantee the palatability of the feed; and the release of the propionic acid cannot be influenced while the ingestion of animals is not influenced, and the mildew-proof effect of the whole slow-release mildew preventive isguaranteed.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a slow-release antifungal agent for feed and its application method. Background technique [0002] According to reports, the annual economic losses caused by mold contamination of grain and feed in the world can reach hundreds of billions of dollars, of which feed mildew accounts for nearly half, and my country's feed output has reached more than 220 million tons in recent years, ranking first in the world. It is a large feed producing country, so how to prevent the feed from being contaminated by mold is very important to reduce economic losses. [0003] At present, the most effective and economical way to prevent feed mildew is to add antifungal agents to feed, but traditional antifungal agents are added in large amounts and have poor palatability. Large, and the volatility of propionic acid is strong, and the loss is large, which increases the production cost of feed an...
