Losses at the silage storage.
It has been discussed many times but the ration what is calculated should be lying at the feeding fence.
Calculations and plans for the feeding rations come from analyses, and a plan, usually made with your feeding advisor.
For some reason it occasionally still goes wrong. The silage might have gotten warm which results in loss of energy and taste. Inevitably, the cows will eat less and receive less energy that what was calculated.
What also happens is that crows, starlings and ducks, spend a lot of time at your roughage storage. Predominantly for the corn kernels. Besides taking away valuable energy and starch, and walking around in the storage, they also shit in the cows food
This also happens in the stable…
By keeping the silage storage as clean as possible, and by pulling a protective cover every day over open silage we can eradicate these forms of energy/taste loss.
Making the stable “bird-proof” won’t be easy.
Also pay attention to what extent the sun can shine on the open surface of the silage, this also dries and heats more than intended.
