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...

AI Technical Summary

Problems solved by technology

[0006] 1. It is easy to produce chemical reactions with alkaline ingredients in the feed such as stone powder and baking soda, and the phosphoric acid becomes phosphate and loses the acidification effect;

[0007] 2. It is easy to react with the starchy substances in the feed to produce a large amount of water, which makes the feed harden, easy to mold, easy to oxidize and deteriorate;

[0008] 3. Adding a high dose of phosphoric acid to the 4% premix will cause the material to turn blue, green, or black, which will affect the appearance, color and smell of the feed;

[0009] 4. Phosphoric acid is a strong acid, directly used in feed will seriously affect the palatability of feed

[0010] At present, the phosphoric acid content in the compound acidulant widely used in the market is between 10% and 60%. If a large amount of uncoated phosphoric acid is directly used in feed, it will seriously affect the quality of feed, make the application effect of acidulant unstable, and even cause adverse reactions. , piglets do not eat food, do not grow meat, are prone to diarrhea, and the economic benefits are low
