Overview
Coated Sodium Butyrate, also known as encapsulated sodium butyrate, is a feed additive produced by coating sodium butyrate (Sodium Butyrate, CAS: 156–54–7) core material with specific coating materials (such as palm oil, sodium carboxymethyl cellulose, chitosan, hydroxypropyl methylcellulose, etc.) through fluidized bed bottom-spray coating, microencapsulation, and other processes, resulting in a gastrointestinal-resistant, targeted sustained-release feed additive. The active component butyric acid has the characteristics of both lipid and water solubility and strong penetrability, which can promote intestinal epithelial absorption in livestock and poultry, balance intracellular pH and microecology. Coated sodium butyrate belongs to the butyrate additive category and is recognized as a highly promising antibiotic substitute. Butyric acid is an important mediator between microbiota and the host, a key regulator, and the primary energy source for the intestine, with effects on increasing feed intake and enhancing immune function. However, untreated sodium butyrate has a pungent odor that significantly affects feed processing and farmer satisfaction. Coating technology effectively masks the odor through physical barriers, prevents deliquescence, protects sodium butyrate from loss during feed processing, and prevents its loss in the crop of poultry and the stomach of pigs, allowing it to reach the posterior small intestine and cover the entire intestinal tract.
Coated sodium butyrate can be divided into the following main varieties by coating process, content specification, and application scenario: Series
English Name
Applications
Pigs
Coated sodium butyrate is most widely used in pig production, particularly for weaned piglets.
Other Animals
Coated sodium butyrate can also be applied to pet, calf, and other animal feeds to improve intestinal health and enhance immunity.
