Milk production demands a lot of nutrients
that are brought to the udder by the blood.
To produce 1 kg of milk, 400 to 500 kg of
blood must pass through the udder. In
addition, the blood carries hormones that
control udder development, milk synthesis,
and the regeneration of the secretory cells
between lactations (during the dry period).
