Our farmers chose the method in which they breed their cows. Many of our farms have a bull around that acts as the stud for all of the cows. However, bulls can be dangerous and because all of our farms are family operations, a farmer may chose to use in vitro fertilization for the cow. This also allows the farmer to choose the best genetics for their herd. For instance, the genetics for performing on grass are best determined by the bull's genetics, and some of the finest bull genetics for this type of behavior come from New Zealand.
