One of the main issues in swine husbandry is efficient and sustainable animal production. Several factors such as raw material prices and increasing worldwide competition force farmers to optimize their production cycles. Animal health is an important parameter for efficient production and is mainly determined by gut health. A healthy well-developed gut is needed for efficient nutrient uptake to achieve sufficient growth and efficient FCR.

Development of immunity

Also, the intestines are the body’s first immune defense barrier and therefore play an important role in the animal’s resilience to invading pathogens. However, due to a variety of stress factors such as pathogenic load, change of feed and social groups, especially in young animals the gut might be underdeveloped resulting in decreased digestion and immunity.

It is known that butyric acid is an effective energy source for the epithelium cells. Butyric acid increases the length of the villi and the small intestine and thus butyric acid increases the absorption surface for in-feed nutrients. However, butyric acid has a strong smell and is corrosive, making handling unpleasant. Current coating techniques are not able to fully overcome the problem of smell, and show insufficient target delivery.

Therefore, alternative forms of butyric acid type products are needed to stimulate gut development.


FRA have developed FRA Butyrin Ultra: a specific formula containing di- and triglycerides of butyric acid and carefully selected essential oils. Feeding this product to piglets, pigs and sows, stimulates gut development and improves animal performance.

Di- and triglycerides of butyric acid

The effect of butyric acid on gut development is intensively studied. Butyric acid serves as energy source for the epithelium cells and stimulates villi growth and length of the small intestines, resulting in more efficient uptake of nutrients and enhanced resistance against pathogens. Di- and triglycerides of butyrate are non-smelling and guarantee an effective target release of butyric acid in the gut.

Essential oils and flavor enhancing aromas

Adding a small amount of carefully selected essential induces a synergistic effect. As well flavor enhancing aromas are added to FRA® Butyrin Ultra to optimize feed intake.
