The number of quality pigs a sow produces from the time she becomes breeding eligible until she leaves the herd is more comprehensive than simply measuring pigs per sow per year. It more fully represents the overall efficiency with which she produces pigs and has a greater impact on profitability of the entire enterprise. Nutrition, genetic selection, environment, animal welfare and health are just a few of the bigger factors that affects productivity. Research is being conducted that will provide pork producers with management tools to improve sow lifetime productivity.
