They will become overactive in the new environment, cannot find relief, and the producer suddenly finds several dead animals scattered around the lot. Be careful also during load-out and shipping when animals are crowded after brief but considerable activity.

Boars not kept together since young will sometimes fight to the death if placed together. Producers should take all precautions if keeping several boar groups, so that escape and subsequent mixing does not occur. The same is true to a lesser degree in sows and gilts, and younger animals.
