Abstract
The composition and output of lipid in thoracic duct lymph has been studied in unanaesthetized calves during the first 6 days after birth. Recirculating lymphatico-venous shunts were established in a total of six calves within 3 hr of birth. The calves recovered quickly from the operation and were able to suck strongly within 1-2 hr of its completion. The concentration of lipid in lymph collected from calves before the first feeding was very high, ranging from 164 to 694 mg/l00 ml. Triglyceride comprised 54% of this lipid with free fatty acid, phospholipid, free cholesterol, and esterified cholesterol comprising, respectively, 6'4, 25'6, 2'5, and 2·5%. Despite the very high output of triglyceride in lymph at this time (mean value O' 86 g/hr), there was no visual evidence of chylomicrons.https://doi.org/10.1071/BI9690189
