Nutritive value of wet distillers' solubles for pigs
Jarmo Valaja | Matti Näsi
Digestibility and nitrogen (N) metabolism were studied to evaluate the nutritive value of wet barley distillers’ solubles (DSB) from an integrated starch-ethanol process for pigs. Eight castrated male pigs (live weight 72-103 kg) were used in a 8 x 3 cyclic change-over design, where the diets were arranged factorially 2x2. The corresponding factors were the protein source (DSB or soya bean meal (SBM)) and the protein level (131 or 162 g crude protein (CP)/kg dry matter (DM)). Faeces and urine were collected in total. The four diets comprised barley, barley starch, minerals and vitamins with either DSB or SBM as the main source of protein. The digestibility of CP(p
