Coating phosphoric acid for feeds

Abstract

The invention discloses coating phosphoric acid for feeds, which consists of an outer stomach coating layer and an inner tablet core layer containing phosphoric acid. The tablet core, accounting for 100 percent, comprises the following components: 30-70 percent of phosphoric acid and 30-70 percent of silicon dioxide, wherein the mass of the stomach coating layer accounts for 5-20 percent of the total mass of the coating phosphoric acid, and the granularity of the coating phosphoric acid is 40-80 meshes. The coating phosphoric acid has no phenomenon of dripping and breakage in the processes of production, machining and stirring and mixing of feeds, and cannot be reacted with alkali components and starch substances in the feeds to cause the problems of moisture absorption, blocking and easy deterioration of the feeds. After piglets are fed, the tablet core is completely released in one hour after entering the stomach; after the phosphoric acid is dissolved and released, chloride is converted into hydrochloric acid to reduce pH values of stomach contents and improve the protein degradation capability by pepsase, so that the starch polysaccharide is hydrolyzed to monosaccharide, thereby improving feed digestibility, effectively reducing nonnutritive diarrhea and obviously improving the production performance of the piglets, therefore, the coating phosphoric acid for feeds has the optimal economic benefit.

Description

Technical field:

[0001] The invention relates to a feed additive and a preparation method thereof, in particular to a coating phosphoric acid for feed and a preparation method of the coating phosphoric acid. Background technique:

[0002] Monogastric juvenile animals such as piglets grow fast, have strong metabolism and strong nutrient utilization ability, but due to immature digestive organs, imperfect functions, poor immunity, insufficient gastric acid secretion, and low protease activity, piglets are weaned and replaced with After the solid feed, the vegetable and animal proteins in the feed cannot be fully condensed in the stomach, the protease function is incomplete, the time for the feed to reach the small intestine through the stomach is too fast, and the feed is not fully digested, resulting in nutritional diarrhea in piglets and resulting in feed utilization. Decreased growth rate and decreased growth performance, commonly known as "weaning stress syndrome in piglet...

[0033] Preparation of coating phosphoric acid

[0034] Weigh 63kg of 40-60 mesh granular silicon dioxide in a conical mixer, add 117kg of pure phosphoric acid solution while stirring, continue to stir for 5 minutes after the addition of phosphoric acid, and discharge to obtain 178.6kg of granular phosphoric acid. Then put the prepared granular phosphoric acid into the fluidized bed coating machine, spray into the stomach-soluble coating solution for coating, and the coating solution formula is composed as follows: polyacrylic acid resin E3012kg; hydroxypropyl methylcellulose 8kg; water 180kg. After the coating solution is sprayed, dry it with hot air at 90°C and sieve to obtain about 201.2kg of coated phosphoric acid. The particle size of the coated phosphoric acid is 40-60 mesh. The weight of the stomach-dissolving coating layer is the total weight of the coated phosphoric acid 11.0%.
