Abstract
The decision to cull a sow from the breeding herd typically occurs after weaning due to poor lactation performance, lameness or if she fails to breed or conceive. Once the decision to cull a sow from the breeding herd has been made, a producer must decide to either immediately market the sow or to increase marketable body weight by feeding her for a period of time. The decision to feed cull sows to add additional body weight is not a simple decision. Many factors such as current cull sow market prices, available housing space, feed cost, and health of the animal contribute to this decision [1]. Revenue from marketing cull sows contributes to the profitability of pork operations, therefore much care should be placed on deciding when to market cull sows.
