Some hogs and sows develop foot problems caused by poor floor designs. Plastic or metal floors in finishing barns can lead to excessive hoof growth that makes walking difficult. Limit use of these types of flooring to younger pigs. Install non-slip flooring in areas where hogs are moved, weighed and loaded. Ensure handling and loading facilities are properly designed to minimize accidental injuries.
Many infectious agents can lead to joint infections which lead to downed hogs.
Proper sanitation and preventive veterinary care as well as accurate diagnosis and treatment of injuries and infections will all help reduce this source of non-ambulatory hogs. Proper nutrition for all stages of production, especially young lactating females, is important to prevent nutritional and metabolic conditions. Diets should be reviewed regularly with swine nutritionists. Handle and move hogs gently to prevent injuries caused by slipping or piling. Hogs with hernias or prolapses as well as those that are unable to walk should not leave the farm unless they can be humanely and promptly moved directly to the plant.
