We mix corn with it from time to time.
More to improve the corn than anything else.
We haven't seen any serious problems with feeding bulls. Did have a bull test low, but the vet blamed infection . Idk. . Most of the cotton today is relatively low in the ingredient that causes problems. And you'd have to feed it for a pretty long stretch before seeing a problem. If there is a problem it will correct itself once you stop feeding the cottonseed.
If it makes you sleep better though by all means just feed something else. Cottonseed if stored properly keeps quite well In my experience
