I know what you mean. The English breeds don't do well in high temperature and high humidity environments.
Would love to be able to create a Super Black Baldie and skip the Angus entirely. Have never had any luck with them. The cows don't milk, don't have enough sense to come in the corral for cubes and the bulls spend the summer standing in the tank.
But I better be careful saying Angus are not ideal, BLACKPOWER will come and get me. LOL
He attacked me on another forum, sent him a message telling him I made an avatar just for him. (Think it fits his personality) Never got a response.
Good Luck with your cattle goals.
Best Wishes
