Portal net appearance of nutrients and energy in growing pigs fed a barley-based diet with inclusion of three different forage meals
Lindberg, Jan Erik; Lundh, Torbjörn; Andersson, Camilla; Gonda, Horacio; Reverter, MarionaAbstract
The cumulative net absorption of energy was reduced with forage meal inclusion, which was mainly due to a lower absorption of glucose. However, there were no diet related differences in the cumulative net absorption of lactate, acetate, propionate, urea and amino acids. The calculated amount of energy from short-chain organic acids appearing in the portal blood, and assumed to be absorbed from the hindgut, was considerably lower (0.33 to 0.63) than the dietary energy available from hindgut digestion. This suggests that a substantial part of the energy made available to the animal by hindgut digestion was used by the gut microflora and/or by the gastrointestinal tissues. It was estimated that on average 0.34 (SD 0.05) of the maintenance energy requirements of a 40 kg pig could be provided from absorbed VFA and lactate.Keywords
