title: The onset of mammary extraction of plasma triglycerides and circulating levels of progesterone during lactogenesis in the cow and goat.
abstract: In untreated cows and goats, the onset of mammary extraction of plasma triglyceride was sometimes detected several hours before parturition, prior to removal of secretion from the mammary glands by offspring and when circulating progesterone concentrations were low. In cows and goats that had secretion regularly removed from the mammary glands late in gestation, the onset of triglyceride extraction occurred up to several days before parturition, when circulating progesterone concentrations were moderately high (up to 3.9 ng/ml in the cow and 6.2 ng/ml in the goat).
