1. Development of butyric acid as feed additive

1980s > Butyric Acid used to improve rumen development

1990s> salts of butyrin acid used for animal performance improvement

2000s> coated salts developed: better intestinal availability and less smell

2010s> A new esterified and more efficient butyric acid is introduced

Today the market is dominated by well protected butyric acid. Feed producers working with these additives have no problems with smell issues and the effect of the additives on gut health and performance is better. The problem with conventional coated products is however the low concentration of butyric acid. Coated salts usually contain 25-30% butyric acid, which is very low.

The latest development in butyric acid based feed additives is the development of ProPhorce™ SR: glycerol esters of butyric acid. These triglycerides of butyric acid can naturally be found in milk and honey. They are the most efficient source of protected butyric acid with a concentration of butyric acid up to 85%. Glycerol has room to have three butyric acid molecules attached to it through so called 'ester bonds'. These powerful connections are present in all triglycerides and they can only be broken by specific enzymes (lipase). In the crop and stomach the tributyrin stays intact and in the intestine where pancreatic lipase is readily available the butyric acid is released

The technique of esterifying butyric acid has proven to be the most efficient way of creating odorless butyric acid that is released where you want it: in the gut.

Tributyrin function

1.Repairs the small intestinal villi of animals and inhibit harmful intestinal bacteria.

2.Improves absorption and utilization of nutrients.

3.Can reduce diarrhea and weaning stress of young animals.

4.Increases the survival rate and daily weight gain of young animals.
