Rice coproducts in pig diets add fat and fiber, but too much fiber can decrease energy absorption and digestibility. A recent study from the University of Illinois characterizes the chemical composition of fiber in rice and rice coproducts, which could lead to diet interventions for improved digestibility.
“Because of rice fiber’s low fermentability, there’s a high upside potential for increased digestibility if we can find specific enzymes that can help degrade those fibers. For pigs, the most important thing is to be able to get more energy out of each ingredient,” says Hans Stein, professor in the Department of Animal Sciences and the Division of Nutritional Sciences at U of I, and co-author of the study published in Animal Feed Science and Technology.
