However, all this depends on the breed and each individual bull. Some breeds that are later maturing (typically Continentals), like Charolais, Simmental, Limousin or Salers, won't start showing puberty until they're around 12 to 16 months of age.
Well, since heifers can obviously be bred when they are younger than a year old and bull calves can be fertile as young as 8 months old it's not a good idea unless of course you want your heifers bred very young. Not all yearling heifers and 8 month old bulls will breed at that young age, but it does happen.
