Composite acidulant for feed as well as preparation method and application of composite acidulant

Abstract

The invention relates to a composite acidulant for a feed as well as a preparation method and application of the composite acidulant. The composite acidulant for a feed comprises the following components in parts by weight: 20-25 parts of fumaric acid, 9-11 parts of benzoic acid, 15-18 parts of methionine hydroxy analog-Ca, 5-7 parts of formic acid, 2-3 parts of sorbic acid, 8-11 parts of phosphoric acid, and 30-40 parts of silica gel. When being used, the composite acidulant is added to a basic ration for piggies in the proportion of the composite acidulant to the basic ration being 0.2-0.4wt% for feeding the piggies. Compare with the prior art, the composite acidulant disclosed by the invention has the advantages that the growth and development and the intestinal tract health of weaned piggies can be improved, the total number of harmful bacteria is reduced, the total number of beneficial bacteria is increased, and the composite acidulant also has the functions of improving the oxidation resistance and the immunity of animals. Besides, the composite acidulant contains mineral acid and organic acid, and the mineral acid is used, so that the addition cost is reduced, and the economic benefits are increased.

Description

technical field

[0001] The invention belongs to the field of feed additives, in particular to a compound acidifier for feed and its preparation method and application. Background technique

[0002] It is generally believed that the types of gut microbes and the proportion of gut microbes have a great impact on animal health. Gut microbes compete with each other for limited sources of nutrients and for adhesion sites in the gut, both of which are necessary for their growth. Existing studies have confirmed that dietary composition and nutrients can have an impact on the ecosystem of gut microbes. In the case of early weaning, piglets transition from easily digestible mother's milk to an unfamiliar diet with high protein content and high acid binding capacity, sudden dietary change stress, and the immature gastrointestinal tract of piglets does not secrete sufficient amounts of Hydrochloric acid (HCl) neutralizes invading acid-fast bacteria, including E. coli and Salmonella, ...
