This photograph shows champion stud Freisian bull Aurora Donor Favour, owned by Ambreed New Zealand. Semen from such bulls is collected, diluted and used to inseminate a large number of cows – and efficient way of using good genetic material for breeding. Each bull is rated on the milk production of his daughters, as well as a number of other characteristics, including behaviour. In August 2008 Aurora was eight years old and had 93 daughters.
