This study determined if exercise during gestation would affect the musculo-skeletal system, production variables, and behavior. Gilts were blocked by BW and assigned to 1 of 3 treatment groups: control (n = 10; no exercise), low exercise (n = 14; 122 m\/d for 5 d\/wk), and high exercise (n = 14; 122 m\/d for 2 d\/wk and 427 m\/d for 3 d\/<br \/>\nwk). All gilts were stall-housed during gestation, and gilts were exercised between d 35 and 110 of gestation.<br \/>\nLameness score, BCS, BW, and blood were taken at multiple points before gestation, and during gestation<br \/>\nand lactation. Blood serum was analyzed for carboxyterminal telopeptide of type I collagen. Sow lying behavior<br \/>\nwas recorded for 3 d after farrowing. Farrowing data included litter weight and size at birth and weaning,<br \/>\nand preweaning mortality. After weaning, 38 sows were slaughtered and muscles and the bones of the<br \/>\nleft fore- and hind-limbs were harvested. Bone density and quality were determined by computed tomography<br \/>\n(CT) scans, dual energy x-ray scans, and bone-breaking force tests. The control group took longer to lie down<br \/>\nthan both exercise groups, and the low exercise group took longer to lie down than the high exercise group<br \/>\n(P &lt; 0.05). The number of pigs weaned was greater in the high exercise group than the control group (P &lt;<br \/>\n0.05). Piglet preweaning mortality was greatest in the control group compared with both exercise groups (P &lt;<br \/>\n0.05). The low exercise treatments exhibited a greater bone density (CT) in the humerus, radius, and tibia<br \/>\ncompared with that of the control group (P &lt; 0.05). The bone density (CT) of the humerus in the low exercise<br \/>\ngroup was greater than that of the high exercise group (P = 0.03). Breaking force in the humerus and femur<br \/>\nwas greater (P &lt; 0.05) in the low exercise group than the control group. Breaking force in the tibia of the<br \/>\nhigh exercise group was greater than the control group (P = 0.01). The tibia of both the low and high exercise<br \/>\ngroups had a greater breaking force (P &lt; 0.05) than the control group. Although there was no benefit of exercise<br \/>\non lameness, differences in bone density and quality, lying behavior, and piglet survivability may provide<br \/>\nuseful insight into alternative housing for sows.<\/p>\n<p>For more information the full article can be found at <a href=\"http:\/\/jas.fass.org\/\">http:\/\/jas.fass.org\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Lameness in breeding-age gilts and sows is a major cause of culling, resulting in increased economic losses and welfare concerns.
