Selacid® is a synergistic blend of free and buffered short chain fatty acids. It is particularly effective in reducing the feed’s buffering capacity in the stomach. The free acids in Selacid make the product effective in supporting the natural barrier against Gram-negative bacteria in the stomach. Moreover, digestion is supported by reducing the stomach pH after feed ingestion. The buffered acids used in Selacid may help to improve the microbial balance in the gastrointestinal tract. The overall result of Selacid is a positive effect on swine and poultry gut health and performance.
