Research report: Digestibility of energy and nutrients in wheat middlings and red dog fed to pigs

Wheat middlings and red dog are two coproducts of the wheat milling process that are used as sources of energy and protein in animal feed. Wheat middlings are granular particles of the wheat endosperm, bran and germ. Red dog consists mainly of the aleurone layer that lies between the bran and the endosperm, along with small particles of bran, germ, and flour. It is often used in extrusion mixtures and as a pellet binder. The composition of wheat middlings varies from mill to mill because of the different conditions under which they are produced.

Wheat and wheat co-products contain more non-starch polysaccharides (NSP) than other grains commonly fed to pigs. Because pigs lack the enzymes needed to digest NSPs, this may affect the digestibility of energy and nutrients. An experiment was conducted to determine the apparent total tract digestibility (ATTD) of gross energy (GE), dry matter (DM), and organic matter (OM), and the concentration of digestible energy (DE) and metabolizable energy (ME) in ten sources of wheat middlings as well as one source of red dog.

Podcast: Absorption of Ca and expression of genes involved in Ca absorption in pigs

Dr. Hans H. Stein summarizes the results of his laboratory's research into the mechanism and regulation of calcium absorption in pigs.

Press release: Rice bran in weanling pig diets does not reduce growth performance

URBANA, Ill. – Research at the University of Illinois has demonstrated that adding rice bran to weanling pig diets does not have a detrimental effect on growth performance. Rice bran is a co-product of the rice milling process which is often added to swine diets; it is relatively inexpensive, and it may improve gut health in weanling pigs.

A team led by Hans Stein, professor of animal sciences at the University of Illinois, fed diets containing 10, 20, or 30 percent of either full fat rice bran (FFRB) or defatted rice bran (DFRB) to weanling pigs. The growth performance of these pigs was compared to that of pigs fed a control diet based on corn, soybean meal, and whey powder. All diets were formulated to contain the same amount of digestible indispensable amino acids.
