and avoids fatty liver. This reduces the incidence
of many metabolic problems. Fatty acids are
released into the bloodstream to lesser extent
and the risk on ketosis is reduced.
By-pass vitamins
LiFT is developed to support the liver at the end
of the dry period and during the start of the
lactation. When adding vitamins to a ruminant
diet, they should be resistant to breakdown in
the rumen.
A number of vitamins is resistant to rumen
breakdown but others, like the liver supporting
B vitamins, need to be protected from rumen
breakdown. LiFT contains by-pass B vitamins for
optimal liver support.
The cowcompensates for this bymobilising body
reserves (Figure 1).
When the cowhas a negative energy balance
and ismobilising body reserves it is essential
to support the liver functionwith B vitamins.
Addition of these vitamins improves liver function
Transitionmanagement:
Combined energy and liver support
Rations for dairy cattle immediately post calving often lack energy. This is because
the energy density of the ration is not high enough to cover the high requirement of
cows at this stage and cows have a negative energy balance.
