A study was conducted to compare production performance of grower-finisher pigs formed into larger groups (108 pigs/pen) to conventional small group size (18 pigs/pen) and to see if this trend in the pig industry is beneficial to producers. Results from the study showed that pigs in the smaller groups had a higher growth rate during the first two weeks. Feed efficiency, ADFI, mortality and morbidity, and body weight variation were also taken into account when finalizing results. Although pigs housed in the large groups had a slight reduction in ADG, their performance was generally not inferior to the smaller group size.
