Characterization of objective feet and leg joint measurements between selection and second gestation and between separate gestation ages in swine

Description
Summary:An abstract of a study by Stock et al evaluating feet and leg joint angle measurements between time of selection and after first, and determining feet and leg joint angle measurements across gestation days is presented. Results suggest that as age increases, leg structure changes, with rear leg joints showing greater variation from selection to first parity than front leg joints. Front leg differences may be significantly different across ages; however, angle differences are small. Results suggest environmental factors such as farm where animals are housed contribute to angle differences. Small angle changes in front leg could indicate structure that carries over the life of the animal; however, rear leg structure still requires further investigation for longevity implications.
