With today’s feed market being highly volatile and reliable protein sources, in terms of quality and availability, becoming harder to come by, amino acid balancing becomes a no-brainer in terms of profitability potential.
“Balancing for crude protein is a thing of the past,” says Dr. Jamie Jarrett, dairy marketing nutritionist with Purina Animal Nutrition LLC. “It is unfavorable not only to your pocketbook, but also to the overall efficiency of the animal.” Excretion of excess nitrogen indirectly diverts energy from milk production into repackaging nitrogen as urea for excretion by the kidney.
To illustrate this point, consider filling a water barrel that has short staves on one side. Any water provided in excess of the shortest stave is waste. The same is true when you consider nutrients that are provided in excess in the ration. The shortest stave on the barrel predicts maximum production in that situation. Everything provided in excess of the lowest stave are wasted inputs.
The goal is to take the “minimum” stave and increase it while minimizing the over-delivery of other nutrients and eliminating its restraint on production. In essence the more equal each stave is the more water the barrel can hold or the more milk the cow can produce and the more efficient she becomes.
Research underlines this, repeatedly showing improvements in milk production of 6-7 lbs.[1] when rations are balanced for metabolizable protein, lysine and methionine. Component yields of 0.3 lbs. of fat and protein accompany this production improvement.
