Why is the use of butyric acid (organic acid) in feed essential to repair damaged intestinal villi and improve FCR in brown layers?

The intestinal tract of a brown layer hen is the primary organ responsible for digestion and nutrient assimilation. Under practical farm conditions, pathogens, coccidia, and dietary fiber can damage the delicate intestinal mucosa, reducing villus height and increasing crypt depth, which leads to poor feed conversion ratio (FCR). Butyric acid, a short-chain fatty acid (SCFA), is highly effective at reversing this damage. Unlike other organic acids that function primarily as acidifiers, butyric acid acts as a direct metabolic fuel source for the intestinal epithelial cells (enterocytes). It is rapidly absorbed and oxidized by enterocytes, stimulating DNA synthesis and cellular mitosis. This accelerates the regeneration of damaged villi, increasing their physical height and surface area for nutrient absorption. Furthermore, butyric acid has strong antibacterial properties against Salmonella and Clostridium in the hindgut. Using micro-encapsulated sodium butyrate ensures the active acid is released slowly throughout the entire length of the intestine. Farmers can read intestinal health protocols in the Poultry Encyclopedia, buy micro-encapsulated butyric acid on Poultry Plaza, check feed grain rates on Poultry Rates, and trade high-yield flocks on Murghi Mandi.
