Body condition scoring in breeding sows monitors nutritional status and allows early intervention to prevent the welfare problems of both under and over-conditioning.
Maintaining appropriate body condition throughout the reproductive cycle is essential for sow welfare. Sows that become too thin during lactation experience chronic hunger and metabolic stress. Those that become over-conditioned suffer from restricted movement, farrowing difficulty, and heat stress. Individual body condition monitoring and responsive feeding management are the welfare-optimal approach in group sow housing.
