Anil. S. S., Anil. L. and Deen. J. 2008. Analysis of periparturient risk factors affecting sow longevity in breeding herds. Can. J. Anim. Sci. 88: 381-389. The association of periparturient risk factors with sow longevity and the validity of sow removal decisions made during the periparturient period were analyzed. Data pertaining to 2066 sows from a commercial breeding herd from the US Midwest were used in this study. The likelihood of removal from the herd within 35 d post-farrowing decreased with a younger parity, the absence of lameness or other health problems, a higher lactation feed intake (LFI) and a greater number of live-born piglets (P
