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.
Cattle are bred at the age of 15 months, and have their first calf at 2 years of age, at which time they begin to produce milk. Dairy cows are not slaughtered until they are too old to produce milk, which at our farm is usually after at least 5 lactations (or a little more than 5 years).
