I've got both, but the bahia seems to be much hardier than the bermuda. Bahia seems to take over the bermuda unless a lot of fertilizer is used. Bahia is about 9.6% protein, less than bermuda, and it's about 57% TDN. When my cows are one it they do well, and their stools stay very loose which tends to make me think that protein is not a problem. Anybody know much about bahia?
