Why is rumen-protected choline so important for the lactation start?
The dilemma for a high-production cow at the start of lactation is lack of energy for milk production. The fullness and energy concentration of a feed ration is often insufficient for a cow to gain sufficient energy from it. Fat conversion increases significantly around and shortly after calving as a result, as a lot of the fat is transported onwards into milk production, but more is also ‘stored’ in the liver (liver fat).
As a nutrient, choline plays a key role, as it cuts the risk of liver fat and ketosis. Vilomix’s Metabolic Booster contains choline, which boosts the transport of fat from the liver, cutting the risk of liver fat and ketosis, whilst also reducing weight loss.
The addition of extra choline in a series of trials has shown its positive effect on output. Metabolic Booster can stimulate the metabolism to convert more nutrients, which means better energy status and startup, and more milk.
Metabolic Booster has added choline in rumen-protected form. Rumen-protected choline has the advantage of not being broken down in the rumen, and is therefore transported to the liver intact, where it boosts fat conversion.
Metabolic Booster is a supplementary feed used in the period around calving.
