Supplying Amino Acids
to the Cow of the Future
By Steve Martin, MS, PAS, Owner/Nutritionist, DNMCmilk
At a recent nutrition conference, a slide presented the gains in milk
production per cow over the last century. Production has steadily
increased due to innovations in nutrition, management, and
genetics, and is predicted to continue its climb into the future.
Using sexed semen, routine on-farm embryo transfer and genomics,
the presentation predicted drastic production increases in the milk
cow of the future.
As a nutritionist, my thoughts went to how we will supply the
necessary nutrients to support these higher levels of milk. In the
coming years, using these genetic tools, your whole herd may be
equal to the top 10% of your current herd. With the demands of more
genetically superior cows, we must become better at fine-tuning
diets to get the most out of every pound of feed.
Meeting the needs for things like starch and fiber is relatively
straightforward. The supply of various fatty acids and amino acids
is more difficult. On the amino acid side, we must be sure to supply
adequate amounts of lysine and methionine, in the correct balance.
Let's look a little deeper into how the nutritionist uses the model to
make decisions based both on biological and economic principles.
There are two ways a nutritionist can build the ration. The first is to
input a ration based on inventories, ingredient availability or simply by
preference. The formulator offers available grains, proteins, byproducts
and forages to the model. The model considers the amino acid supply
in each of the feedstuffs and predicts the microbial and feed protein
supply leaving the rumen. The model will predict the milk output from
this blend and indicate various deficiencies. The nutritionist can then
make further adjustments to address these deficiencies. Many diets
are successfully generated using this approach.
The second way to design a ration is to use the linear program (LP)
function and let the model solve for the best ration possible using
the ingredients offered. In this approach, ingredients are allocated to
meet requirements at the lowest possible cost. Using the LP function,
rumen-protected lysine and methionine products can compete with
and be combined with amino acids in other ingredients including
grains, proteins, and forages. Logistics should also be a consideration
when replacing commodity ingredient amino acids with a more
convenient premix or mineral blend.
In a recent field trial, we used this LP formulation approach to replace
blood meal with AjiPro®-L. This blood meal was bulk shipped to the
dairy and it was not a good use of an entire commodity bay. So, we
replaced the blood meal with a small amount of AjiPro®-L delivered in
a mineral premix, and were able to support the same lysine supply
for no change in feed cost.

The goal in this field trial was to replace the bay of blood meal and
not add cost - goal accomplished. However, lysine supply still lagged
behind energy. The next step for this herd could be to invest 6 cents
of additional AjiPro®-L to elevate MP and Lysine supply. The additional
potential 2 lbs of extra milk will offer an excellent ROI on the 6 cents.

The goal of a good nutritionist is to supply the correct nutrients
for the least cost to support the most profitable level of milk
production. Modern formulation software allows this to be a very
detailed process. Amino acids found in commodity ingredients like
soybean meal or canola can be augmented by just the right inclusion
rate of Rumen-protected lysine or methionine. If we are to meet the
nutrient supply needs of the cow of the future, we must employ this
technique and take our ration formulation to the next level.
