Problems solved by technology

Powder products are often simply mixed with several acids such as lactic acid, citric acid, fumaric acid, etc., and the carrier, which may cause these acidifiers to directly react with nutrients such as vitamins in the feed after being added to the feed, reducing the Nutritional effect of feed
[0004] There are also acidulant products using coating technology in China, such as patent No. 200310106338.7 and patent No. 200710029691.8. However, these products first use carriers (such as silica, etc.) to absorb liquid acids (such as lactic acid), and then Coating, which tends to reduce the acid content of the overall acidulant

Abstract

The invention relates to a coated acidifier and a preparation method thereof. The coated acidifier is made by mixing acids with an emulsifier, adding a solution of compound shell material and spray-drying. During the manufacturing process of the coated acidifier, no carrier additive for adsorbing acids is added, so that the acid content of the coated acidifier is increased. Owing to encapsulationof the compound shell material, the coated acidifier does not contact or react with vitamins and other nutrients in feed, so as to effectively ensure nutritive value of the feed. The coated acidifieris fully released when reaching the stomach of a suckling piglet, so as to achieve the effect of reducing gastric pH. Therefore, the coated acidifier overcomes the problem that a liquid acidifier is inconvenient to use and hard to preserve. Besides, the total acid content of the coated acidifier is higher than that of other coated acidifiers. The coated acidifier is very suitable for being used in the weaning period and within six weeks after weaning of sucking pigs in sucking pig breeding industry, and can effectively maintain low pH value of gastric juice and greatly increase the average daily weight gain of sucking pigs and the feed utilization efficiency.

Description

technical field [0001] The invention relates to the field of feed additive production, in particular to a coating acidifier and a preparation method thereof. Background technique [0002] In the breeding industry of suckling pigs, it is necessary to use feed additives. Lactating piglets can metabolize lactose in milk into L-lactic acid under the action of lactase to maintain the low pH value of gastric juice. Obtaining milk also cannot obtain lactic acid and cannot maintain the low pH value of gastric juice. During this period, if the addition of lactic acid-based acidifiers to the feed can significantly improve the daily gain and feed utilization efficiency of piglets, this effect is especially important during the weaning period and six weeks after weaning. At the same time, since organic acids such as lactic acid can effectively inhibit the growth and reproduction of harmful bacteria such as Escherichia coli and Salmonella, adding acidifiers to feed can also improve the...
