%X A single dose of up to 480 g of safflower oil was administered, on two occasions, to each of two lactating cows. The changes in the absorption of lipid from the small intestine were studied by determining the changes in the output of lipid in thoracic duct lymph. There was a significant increase (P<O'Ol) in the output of total lipid, triglyceride, and free fatty acid in the lymph, between the 6th and 7th hr after oil.feeding. The output of total lipid began to decline at 17 hr after oil.feeding but did not appear to return to the level observed before oilfeeding until 2-3 days later. Although the average rate of entry of chylomicron triglyceride into the blood vascular compartment increased from approximately 15 g/hr before, to 30 g/hr after oil.feeding, there were only slight changes in the concentration of triglyceride in blood plasma. It was concluded that the rate of turnover of the plasma pool of chylomicrons was extremely rapid.
