I don't know if it will turn him off breeding...but I seriously doubt if he's been locking with females already. I think worst case, you may have just stolen his mojo for the current session.
I'm not aware of many others' common practices, but if I have a male in with a female, I don't take him out for any reason other than he's locked up and is done, or there has been no courting behavior at all...and they are always offered food during break periods. This time of year, I work feeding schedules around breeding schedules.
