Effect of Removing Market Ready Pigs on Performance of Their Pen Mates

Iowa State University Animal Industry Report 2004. Results of this study suggest removing 25% or 50% of market ready pigs two weeks prior to the final marketing date does not affect test performance of pen mates. This study does not support the commonly held producer belief that removal of a percentage of market weight pigs will improve overall pen performance. If pigs are provided the space per animal utilized in this study, producers could reduce the labor associated with marketing by selling all of the pigs as a single group.
