Lactic acid is also used as green feed storage agent and forage ripening agent

Description

Lactic acid is a carboxylic acid with molecular formula of C3H6O3, which contains hydroxyl groups and belongs to α- Hydroxy acid (AHA). In aqueous solution, its carboxyl group releases a proton to produce lactate ion CH3CH (OH) coo −.

Applications

1. Lactic acid is also used as green feed storage agent and forage ripening agent;
2. As growth promoter in pig and poultry feed. Lactic acid can reduce the pH value in the stomach, activate digestive enzymes, improve the ability of amino acid digestion, and is good for the growth of intestinal epithelium. Piglets fed diets containing Acidifiers for several weeks after weaning can gain 15% weight during weaning;
3. Lactic acid inhibits the growth of microorganisms. Suckling piglets will be infected with diseases caused by Escherichia coli and Salmonella. Adding lactic acid to the feed can prevent the growth of pathogens in the lower gastrointestinal tract of piglets;
4. Lactic acid can be used as feed preservative and enhance microbial stabilizer of feed, grain and meat processing products by-products;
5. Adding lactic acid to the drinking water of poultry and piglets can effectively inhibit the growth of pathogenic bacteria and increase the rate of animal weight gain.
