compared with the barley-based diets. Pigs offered the barley-based diet+enzyme composite had decreased faecal Nitrogen (P = 0.010) compared with the barley-based diet. Pigs offered the wheat-based diets+β-glucans+enzyme composite had an increased urine:faeces Nitrogen excretion ratio (P = 0.004) compared with the wheat-based diet+β-glucans diet.
