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.
1 Cows should be bred 45 to 80 days after they have calved, depending on age and condition. 2  The optimum bull-to-cow ratio is 1 bull per 10 to 30 cows, depending on the size of the pasture, and the bull's age, promiscuity/libido and experience. Bulls reach peak fertility by 20 months of age, after 20 months of age it can only drop, barring illness or injury, with proper nutrition most bulls fertility will not start to decline until after 6-7 years of age.
