My pastures are very heavy in white clover. I have been grazing this way for a very long time. I put the clover in the pasture and it has been there almost 20 years. Can't remember the exact date, but the grass and clover was planted before cows were brought in.
This is my recipe for heavy clover grazing. Feed Rumensin in your mineral and if you don't have it in your mineral, you may have to mix some heavily where you can feed a small amount of feed to get it in them. But in the summer, my Rumensin is in my mineral. Cheaper to feed it that way.
Rumensin keeps down frothy bloat by 80% and when you have them on that much clover, always keep a dry hay bale in the pasture for them to go to. The very dry hay slows down digestion, and it is thought that the stemy dry hay helps to keep but bubbles broken up. I have noticed that my cows will go to that dry bale late in the afternoon, right before they lay down and they will all be around. But they don't eat that much and it takes a while for them to go through it, so they just want that dry hay when they lay down.
Never lost a single cow to bloat. Lost one where it laid down in a slight drainage depression, and she got her feet above her head and could not get up. She laid there that night, and when I went out in the pasture the next morning, she was pretty much gone. Made me sick.
