Extract

Environmental problems in pig rearing have led to intensive efforts to reduce nitrogen excretion (NE) while maintaining constant production levels. High concentrations of lactose in piglet diets have been shown to improve N digestibility (ND) (O’Doherty et al., 2002) and increasing the digestibility of the feed N is a major factor in reducing NE to the environment. The hypothesis of this study is that high lactose inclusion will allow for reduced crude protein (CP) concentrations in post weaning diets.
