Increases Milk Production

Numerous studies have shown that supplementation with Cow Start significantly increases milk production when compared to un-supplemented Control Cows (+1.3kg/day, P<0.05) and also to cows supplemented with a calcium only supplement (+0.8kg/day, P<0.10).
A meta-analytical review of Cow Start research shows that no matter the production system (from 6,000kg grass based, 9,000kg mixed and up to 12,000kg intensive indoor production) Cow Start consistently increases milk production by ~4% over the full lactation.
The research results also shown a consistent increase in Kgs of milk fat and protein and some studies have shown a statistical increase in milk Fat %. Study 2
