Factors Affecting Lipid Output and Flow of Thoracic Duct Lymph in Newborn Calves

Abstract

The factors affecting lipid absorption in unanaesthetized calves less than 24 hr old have been studied by comparing the output of lipid in the thoracic duct lymph of calves fed one of the following diets: (1) colostrum, in which the colostral fat was replaced with milk fat globules; (2) milk; (3) colostral whey containing milk fat globules; (4) isotonic saline containing milk fat globules. The animals were fed after they had recovered sufficiently from the operation to stand and suck from a nipple feeder.
