Problems solved by technology

However, the existing acidifiers have the disadvantages of large single addition, strong corrosion, and poor palatability, and the acidifiers are easy to react with baking soda, starch and other substances in the feed, and lose the acidifying effect before reaching the action site

Embodiment 1

[0026] In the core material of this example, the acidifying agent is a mixture of phosphoric acid, benzoic acid and zinc benzoate in a mass ratio of 1:5:2, the carrier is porous silica with a diameter of 1 μm, and the mass ratio of the acidifying agent to the carrier is 1 : 0.2. The first capsule wall is sodium alginate, the second capsule wall is hypromellose phthalate, and the mass ratio of the core material, the first capsule wall and the second capsule wall is 1:0.02:0.06.

[0027] The preparation method of this embodiment is as follows: load the acidifying agent on the carrier, for example, by simply mixing or drying the solution after mixing, and the carrier will agglomerate during the mixing process to obtain a core material; the natural polymer material Disperse in water to form a wall material dispersion, spray the wall material dispersion on the floating core material, spray for 3 minutes at 25°C, and then float and dry at 60°C to form a primary coating feed additive...

Embodiment 2

[0029] In the core material of this example, the acidifying agent is a mixture of phosphoric acid, benzoic acid and zinc benzoate in a mass ratio of 1:3:1, the carrier is porous silica with a diameter of 5 μm, and the mass ratio of the acidifying agent to the carrier is 1 : 0.2. The first capsule wall is protein, the second capsule wall is polyvinyl alcohol phthalate, and the mass ratio of the core material, the first capsule wall and the second capsule wall is 1:0.05:0.1.

[0030] The preparation method of this embodiment is as follows: load the acidifying agent on the carrier, for example, by simply mixing or drying the solution after mixing on the carrier to obtain a core material; disperse the natural polymer material in water to form a wall material Dispersion, spray the wall material dispersion to the floating core material, spray at 15°C for 5min, then float and dry at 50°C to form a primary coated feed additive; disperse polyvinyl alcohol phthalate in water and Prepar...

Abstract

The invention relates to a coated replacement-resistance type feed additive as well as preparation method and application thereof. The feed additive comprises a core material, a first capsule wall coating the core material and a second capsule wall coating the first capsule wall; the core material comprises an acidifying agent and a carrier, the acidifying agent comprises phosphoric acid, benzoic acid and zinc benzoate, and the mass ratio of phosphoric acid to benzoic acid to zinc benzoate is 1: (3-5): (1-2); the mass ratio of the acidifying agent to the carrier is 1: (0.2-0.5); the first capsule wall is made of a natural high polymer material and forms sealed or non-sealed coating on the surface of the core material; the second capsule wall is an enteric coating, and the second capsule wall forms a sealed coating on the surface of the first capsule wall. The coated replacement-resistance type feed additive can protect an active substance acidifying agent, so that the additive can act on specific organs such as intestinal tracts, the palatability and the corrosivity are improved, and the additive can be slowly released.

Description

technical field [0001] The invention relates to the field of feed additives, in particular to a coated antibiotic-replaced feed additive and a preparation method thereof. Background technique [0002] Feed additives refer to small or trace amounts of substances added to feed in order to meet animal nutritional needs, give full play to animal production capacity, increase feed efficiency, and improve feed quality. Its dosage is usually a few percent to a few parts per million. Although the dosage is small, it has a great effect. It can promote growth, increase the output of meat, eggs, and milk, shorten the feeding cycle, improve reproductive ability, reduce diseases, and reduce feed consumption. cost. According to different functions, feed additives can be divided into two categories: nutritive and non-nutritive. Nutritive feed additives refer to amino acids, vitamins, minerals and other nutrients needed for animal growth that are contained in supplementary feed but are ins...
