Influence Of Energy And Protein Intake During Lactation On Body Composition Of Primiparous Sows, J. H. Brendemuhl, A. J. Lewis, E. R. Peo, Jr.
Department of Animal Science: Faculty Publications
The effects of energy and protein intakes by 32 primiparous sows during a 28-d lactation on sow and litter performance and sow body composition and bone properties were examined. Dietary treatments were energy intakes of 8 (LE) and 16 (HE) Mcal of ME/d and protein intakes of 380 (LP) and 760 (HP) g of CP/d in a 2 x 2 factorial arrangement. Sows fed diets that were inadequate in either energy or protein lost more weight than did sows fed the HE-HP diet, but back fat losses were greater when energy intake was deficient than when protein was deficient.
