Poor sow longevity in commercial breeding herds can lead to economic inefficiency and animal welfare concerns. Reproducing females are the most valuable animals in the herd and it is estimated that 40 to 50% of sows are culled before their third or fourth parity, a time at which initial replacement costs have not been met. The reasons for culling sows and the rate of removal may be influenced by many factors including housing, genotype, management, disease, nutrition and market trends. Regardless of the cause, poor longevity results in larger replacement rates and, consequently, larger gilt pools which translates into higher production cost. Gilts are less productive than sows; their offspring have greater mortality, reduced growth rate, and poorer feed efficiency in the nursery and grow-finish phases of production. Additionally, there is a disease risk when new animals are introduced into the breeding herd. An improvement in longevity can result in decreased replacement costs and production cost and a greater proportion of mature sows in a herd that have reached their maximum productivity.
