Abstract
In two calves fed milk replacers containing hydrogenated marine fat, collection of the duodenal chyme was carried out over a 24 hr. period, when the calves were about one and a half weeks old. The fat was partly broken down to free fatty acids (F.F.A.) before entering the duodenum. Hydrolysis was probably due to pregastric esterase. No hydrogenation of the unsaturated fatty acids was observed.
Sammendrag
Artikkelen omhandler oppsamling av duodenalchyme fra to kalver med re-entrant duodenalfistel. Forsöket varte ett dögn og kalvene var ca. 1½ uke gamle. De ble fòret med en melkeerstatning, hvor hydrogenert marint fett, smeltepunkt 31–33° C og 38–40° C, var fett-kilde. Triglycerider ble delvis hydrolysert til frie fettsyrer i löpen. Dette var trolig forårsaket av pregastric esterase. Det skjedde ingen hydrogenering av de umettede fettsyrene.
