Short summary
The productive longevity of sows in breeding herd systems has become a key evaluation metric due to its importance with respect to both profitability and animal welfare. In the current economic climate, associated with rising costs of feed, a sow's productive life plays one of the most important roles in determining the profitability of the system. Therefore, it is essential to understand the factors that influence sow removal from a herd.
