Sow mixing strategies can affect reproductive performance, sow well-being and the economics of the operation. Mixing sows is a critical aspect of group housing so it needs to be better understood. The three time points that mixing can occur are at weaning, right after breeding when sows are not in heat and at four weeks post-breeding when they are confirmed pregnant. All these time points had similar results, with earlier mixing resulting in slightly less stillborn piglets and a higher pregnancy rate. A mathematical model to determine the economic risks of mixing strategies for sows is being developed as well. There are many options that can be used when mixing in group housing systems.
