Expression of Kyphosis in Young Pigs Induced by a Reduction of Supplemental Vitamin D in Maternal Diets and Vitamin D, Calcium and Phosphorus in Nursery Diets
By altering vitamin D, calcium and phosphorus concentrations in maternal and nursery diets, researchers at the University of Wisconsin Madison induced kyphosis - an abormal spinal curvature - in young pigs that was similar to that observed in spontaneous outbreaks in afflicted herds.
