Calf prices have steadily increased for several years. Since spring 2014, replacement female prices have remained at record levels as well. It is only reasonable that bull prices would follow the trend. This has led many producers to explore options to owning enough bulls to cover their cows in a defined breeding season. Estrus synchronization and timed artificial insemination (AI) are an economically viable alternative to owning a bull if the producer has multiple bulls. There are many benefits to synchronization and AI, including a tighter calving season, increased weaning weights from older calves and better genetics.
The tighter calving season is a result of estrus synchronization and timed AI, followed by natural breeding for the remainder of a 90-day season. Some scenarios are explored in the tables. Each of these assumes a
