The major costs in producing pork are feed costs and the costs associated with the time taken to reach a desired slaughter weight. Pig breeding programs aim towards reducing these costs by selecting the most efficient pig. Selection of breeding pigs can be based on the ratio between growth and feed intake, where these traits are measured over a fixed weight- or time-interval. If there are any differences between animals in performance patterns during the test period, they are not taken into account when animals are selected using this strategy.
