Extract

In pre-ruminant calves the oesophageal groove reflex allows milk to bypass the developing rumen and is a mechanism by which dietary fatty acids can be delivered directly to the small intestine. This experiment was a pilot study carried out to establish the extent and time course of the changes in plasma fatty acid composition in calves fed milk supplemented with oils of differing fatty acid composition and allowed minimal access to roughage (straw bedding). The work was carried out to provide baseline data for a longer study with calves in which rumen development will be encouraged by feeding solid food but the oesophageal groove reflex will be maintained through long term milk feeding and used as a means of delivering polyunsaturated fatty acids (PUFA) directly to the small intestine.
