As part of digestibility and energy metabolism studies in intact and ileorectostomized growing pigs model experiments were carried out on sampling techniques and the influence of storage conditions on CO2 and volatile fatty acid production in chyme. Results on the formation of CO2 and VFA in chyme and faeces are given. They indicate that chyme from the small intestine can be subjected to bacterial and enzymatic changes outside the animals and therefore must be stored in a cool place. In the chyme of IRA animals with closed colon descendens (end-to-end anastomosis) significantly reduced VFA contents were found in comparison to animals with open colon descendens (end-to-side anastomosis).
