Feeding concentrate at “Peak Yield”

From the version DelPro 5.2 it is possible to use a feeding table at “Peak Yield”.

The concentrate feed for cows up to about 100 Days In Milk (DIM) is often a point of solid discussion:
Do we use an invariable feeding table or not?

These cows must be given the opportunity to give a lot of milk, even though they could temporarily decrease production. Of course, these cows require a lot of energy, (concentrated) feed.

But many advisers and veterinarians observe that during this period some cows who aren’t very comfortable and do not give a lot of milk in general, they are worse off with too much of concentrated feed.

Since DelPro 5.2 there is the possibility to operate at Peak Yield.

This is a nice system for feeding cows after the start-up period, for example up to 40 DIM, and then from about 40 days to 100 DIM go feeding on Peak Yield table.

Then the cows that give a lot of milk get the food that is due to them, but cows that for some reason give too little milk, for example: she has calved too soon, then she will only grow from much concentrate, which is too expensive and gives often problems later on.
Or she has problems with her rumen or claws and therefore too little roughage intake, and therefore she never gets (for longer time) high production. That cow should get less – for her – rumen acidic concentrate feed.

If a cow that gives a lot of milk still temporarily decreases in production, she will continue to keep the concentrate that belongs to the highest production she has given as a 7-day average during this period.

So the concentrate feed amount remains stable.

After 100 days in milk, the negative energy balance period should be depleted. If the cow gives less milk, then you should also decrease the concentrate.

So then the advice is: just feed on “Milk Yield” table.
