Butyric acid therefore appears to be both bactericidal
and a stimulant of villi growth. As with any short-chain
fatty acid, bactericidal activity of butyric acid is greatest
when the acid is undissociated. Bolton and Dewar (1965)
indicated that free butyrate quickly disappeared in the
upper digestive tract, and whereas almost 60% of the
feed source was intact in the crop, less than 1% was
recovered from the upper small intestine. The efficacy
of butyrate likely will be improved if it is protected from
immediate absorption in the upper tract. In this study,
we tested butyrate in the form of a mixture of mono-, di-
, and triglycerides for its potential in sustaining broiler
health and performance.
