Feeding Glycerin to Swine Can Be Done
(Prairie Farmer) Researchers recommend feeding glycerin up to 15%. Glycerin did not have an effect on meat quality.
An increased interest in biofuel production and a growing need to find cost-effective livestock feedstuff alternatives has led University of Illinois researchers to further evaluate the use of glycerin in swine diets.
This study, led by U of I graduate research assistant Omarh Mendoza, was published in the Journal of Animal Science and reports that swine diets may include up to 15% glycerin and achieve similar performance to a conventional corn:soybean diet.
“Glycerin is not a new product, but little is known about its role as a feed ingredient for swine,” says Michael Ellis, U of I professor in the Department of Animal Sciences. “Previous studies have shown variable results.”
Glycerin is a major co-product of biodiesel production. This resulting liquid energy source is sweet and palatable. While it’s more commonly used by humans, it has the potential for greater inclusion in livestock diets. READ MORE
