Effects of Resistant Starch from High Amylose Corn on Swine Growth, Feed Effciency, and Fecal and Blood Volatile Fatty Acid and Aromatic Concentrations

Researchers believe resistant starch (RS) in high amylose corn reduces offensive odors and unsavory pork flavors. The effect of RS on swine growth, feed efficiency, and blood and fecal volatile fatty acids (VFAs) and aromatic compounds (ACs) is unknown. An eight-week feeding trial was conducted using 20 feeder pigs randomly assigned to treatment diets based on weight and sex. The RS diet contained a protein supplement, high amylose corn (HAC), and traditional corn (TC). The ratio of HAC to TC in the RS diet was 1:3 for 42 days and 1:0 for 14 days. The normal diet contained a protein supplement and TC only. The pigs were weighed and fecal samples were collected weekly from both groups. At the end of the study, blood samples were collected from each animal. Swine growth and feed efficiency were not affected by the RS diets, but alterations in VFAs and ACs were observed.
