Cows often feel exactly what they need.
For this reason it could be useful to always give some extra hay or straw for free at their troughs. If everything goes well, your well rationed feed of corn, grass and extras should be so good they’ll always come back for more of that! The first day they eat the hay for curiosity, but after that they only eat from the hay when they need it. The cows that take some extra hay are the ones that have just given birth or aren’t feeling very well.
Just keep in mind that the hay has to be tasteful and good.
Even if there is, for a moment, not much good food in front of the troughs, the cow will eat some hay and keep its Pens / rumen and PH stable.
If they don’t take the hay, it means that the cows feel well with your ration!
There are also dairy farmers that have good experiences with setting a box of sodium bicarbonate or salt at the troughs. You’ll see an increase of consumption during warm weather.
Then the cows who don’t need it won’t take it.
Discuss the possibilities with your feeding advisor.
