Extract

It is known that feeding frequency affects the insulin status of lactating ruminants (Sutton et al, 1988), and that this may influence milk composition. It is unclear, however, whether these effects are due to modulation of mammary metabolism, or regulation of substrate distribution. The present study aimed to establish whether the partition of blood flow to the mammary gland is responsive to insulin and nutritional status.
