The aim of the experiments was to establish new data for a factorial derivation of energy and protein requirements in pigs. In a 3 x 3 factorial design with 3 variants of parity (1, 2 and 4, age of sows) and 3 levels of energy supply (120, 100 and 80, and 80, 100 and 120% of recommended intake in pregnancy and lactation, respectively). Evaluation was by indirect calorimetry and the slaughter technique.
