In a series of experiments involving 3,184 pigs, wheat was compared with barley in the diet of growing-finishing pigs and with a barley-maize combination in the diet of weaned pigs (10-25 kg liveweight). Wheat and barley from 2 years were used during the course of the experiments. Chemical composition of cereals varied widely between seasons. Digestibility studies on the cereals from one season indicated that wheat had 10% higher DE content than barley, 16.28 and 14.77 MJ DE/kg DM, respectively. Wheat had on average 14% lower lysine content than barley. There were no digestive or health problems encountered subsequent to including up to 77% and 66% wheat in the diet of growing-finishing and weaner pigs, respectively. The higher energy content of the wheat resulted in fatter carcasses but there was no indication that the wheat diets responded differently from the barley diets to lysine supplementation. Wheat may replace maize in high-energy weaner diets with no effect on growth rate or feed utilisation efficiency.
