Editor’s note: The following is part three of a four-part series that will help you to evaluate different breeding programs, which bulls are optimal for your herd, and how much they’re worth. (See part one and part two).
Sire selection often encompass a variety of factors such as how well a bull fits into the breeding objectives of your operation, breed, conformation, pedigree, birthweight, and price. Recent surveys from western Canada in 2014 and 2017, Ontario in 2015/16, northern Ontario and Quebec in 2015/16, and Atlantic Canada in 2016/17 production years asked respondents to rank their top bull selection criteria. There wasn’t a lot of variation between regions with breed, conformation, pedigree, birth weight, individual performance, expected progeny differences (EPDs), and temperament all being highly ranked by survey participants.
Some of the criteria, like breed, may influence sire selection due to the desire to capture heterosis or breed complementarity effects. Conformation is important for longevity and ensuring the bull gets the job done during the breeding season. Having a bull with a desirable temperament makes everyone’s lives easier, especially if there are children or older individuals involved in the operation. Individual performance and birth weight may give some indication of how the bull’s progeny may perform, but a better indicator in this area is actually the bull’s EPDs. Response to selection using EPDs is 7-9 times more effective than selecting based on individual animal performance7.
The question is, how well do these various selection criteria translate into profit? Continue reading
