Extract

It is considered that the rate of glucose uptake by the mammary gland is the main regulator of lactose synthesis (Threadgold and Kuhn, 1984) and hence the main factor determining milk production (Faulkner and Peaker, 1987). GLUT1 is the only glucose transporter that has been found in lactating mammary tissue (Burnol et al, 1990). The aim of this experiment was to determine whether GLUT1 mRNA could be detected in sow mammary tissue, to investigate how abundance of GLUT 1 mRNA in mammary tissue changed between late gestation, early lactation and established lactation, and to establish whether this was correlated with milk output and/or feed intake.
