We investigated the effect of body protein mass at parturition and different degrees of body protein loss in lactation on sow performance. In a 2x2 factorial arrangement, 77 Genex gilts were fed to achieve either a standard or high body mass at parturition and to lose either a moderate (MPL) or high (HPL) amount of protein in lactation.
