Anywhere from 1 -8. I personally have never bred over 8 females with one male. However, with that said, most of my males will see 4 or 5 females. Some special projects may only get 1 or 2 to prevent overproducing a project, or some males that are really important, that I think will be in demand the following season may see as many as 7 or 8.
I hope that helps,
