Research Report: Amino acid digestibility in heat damaged sunflower meal and cottonseed meal fed to growing pigs

Little information is available about the effects of heat processing on amino acid digestibility in sunflower meal and cottonseed meal. Furthermore, equations to predict the concentration of digestible amino acids in sunflower meal and cottonseed meal from the analyzed nutrient composition have not been reported. Two experiments were conducted to determine the standardized ileal digestibility (SID) of amino acids in sunflower meal and in cottonseed meal fed to growing pigs, and to test if regression equations could be developed to predict the concentration of SID lysine in sunflower meal and cottonseed meal.

Press release: Feeding corn germ to pigs does not affect growth performance

URBANA - Inclusion of corn germ in swine diets can reduce diet costs, depending on the local cost of corn germ and other ingredients. Recent research conducted at the University of Illinois indicates that corn germ can be included at up to 30 percent in diets fed to growing pigs.

"In previous research we had seen that pigs do very well on diets containing 10 percent corn germ, so we wanted to investigate if higher inclusion rates can be used," said Hans Stein, professor of animal sciences at Illinois.
