Manufacturing method of moldproof feed additive

Abstract

The invention discloses a manufacturing method of a moldproof feed additive, which comprises the following steps: A. preparation of mustard seed extract or dark plum extract: putting mustard seed or dark plum in a glass container, adding a 95 wt% ethanol solution into the glass container, immersing for 3 hours, putting the glass container in water, treating in a 50 DEG C water bath for 8 hours, and filtering out the liquor; putting the glass container containing decoction dregs in water, treating in a 60 DEG C water bath for 10 hours, filtering out the liquor, merging two liquors, diluting until the concentration is 30 wt%, and naturally cooling to room temperature to obtain the corresponding mustard seed extract or dark plum extract for later use; B. adding hydroxybenzoate into carbon black and gypsum powder, and uniformly mixing; C. adding garlic oil into the mustard seed extract or dark plum extract prepared in the step A, and uniformly stirring; and D. adding the mixture obtained in the step C into the mixture obtained in the step B, sterilizing under ultraviolet irradiation, and packaging to obtain the moldproof feed additive. The manufacturing method is simple; and the prepared product has the advantages of simple proportioning, no peculiar smell and favorable palatability, and is convenient to use.

Description

[0001] Technical field: [0002] The invention relates to the technical field of feed, in particular to a method for manufacturing an anti-mold feed additive. [0003] Background technique: [0004] China is a large animal husbandry country. In the process of animal husbandry, especially large-scale farms, due to the need to reduce costs, they basically do not purchase pre-configured full-price feed, but configure their own. In the process of preparing feed, due to the large amount of use, usually a large amount of feed is prepared at one time for storage and backup, and the feed is prone to mildew during storage, which is not conducive to storage. In order to prevent the feed from going moldy during storage, anti-fungal agents are generally added to the feed formula. At present, the feed industry mainly uses single or compound antifungal agents based on organic acid salts (such as calcium propionate, etc.), compound organic acids (such as propionic acid, etc.) and ammoniu...

Problems solved by technology

Although there are many varieties of existing antifungal agents, they mainly have the following deficiencies: they are irritating and corrosive, and have a great impact on the palatability of the feed, causing the nutritional value of the feed to decline or the feed to have a peculiar smell; The cost of adding is relatively high (the usual amount of adding is about 2 kg / ton)
