Ajinomoto launches new AjiPro-L protected lysine for dairy cows



Ajinomoto Heartland, LLC, has introduced AjiPro-L, a protected lysine source that boosts milk production while saving space in the diet for other nutrients.


Over the past decade, numerous studies have shown that the amino acid lysine is either first-limiting or co-limiting with methionine in dairy cows when fed high corn-based diets. But without protection from rumen organisms, lysine quickly gets digested in the rumen and is little use to the cow itself.


AjiPro-L formulation provides 80% rumen protection, and other studies show the lysine from the product is making it into lower intestine where it can be absorbed and used by the cow. In three trials, AjiPro-L increased milk production an average of 2 litres per cow, per day over control diets.


To supply 10 grams of lysine to the cow 230 grammes of blood meal (in the US) must be fed. To supply the same 10 grams of lysine via AjiPro, just 62 grammes. That leaves about 150 grammes of ration "space" that can be used for other nutrients in the TMR.
