Thirty crossbred sows averaging 118.18±12.2 kg of BW, backfat thickness of 13.82±1.42 mm and 220 days old were assigned to a completely randomized design in a split plot scheme with 10 replicates and parturition orders included in the plots (3 x 3 factorial arrangement) and CP ingestion levels (10.0, 13.5, and 17.0%) in the sub-plots. The effects of dietary CP ingestion levels on female performance in three complete successive reproductive cycles were evaluated during the pregnancy. Sow weight gain in […]

Three treatments were accomplished (10.0, 13.5, and 17.0% of CP) to evaluate the effect of dietary CP levels on the reproductive performance of 36 females (12 females per treatment) in the first pregnancy. The diets were formulated to contain (or to exceed) all the nutrients to meet the animal requirements, with the exception of CP, according to NRC (1998). Although the protein was diluted with starch, the amino acid proportion was constant in all diet, due to the constant relation […]
