Tender spring grass is very tasty for cows and also contains many nutrients. The result is more milk and more milk protein.
The cow's rumen does have to get used to this spring grass.
Fresh grass is not silage grass! Try to keep the feed ration balanced and adapted to the new situation in terms of energy, supplementation with protein and concentrate.
Discuss this in advance with your feed advisor and start grazing slowly.
Fresh spring grass often contains a lot of sugar, which can lead to higher rumen fermentation with the risk of rumen acidosis.
Fresh spring grass is also less rich in structure than silage grass, which reduces the milk fat production in the cow.
The decrease is also caused by the fact that spring grass contains a lot of unsaturated fats.
These unsaturated fats block the production of milk fat in the cow.
Therefore, start grazing on plots with structured grass, do not start on plots with “generous” fertilization.
If this is insufficient, add extra structure to the feed ration.
Chopped straw, hay or rapeseed straw are fine for this.
