Extract

Due to the introduction of more stringent environmental controls through the implementation of current and impending environmental legislation, dietary crude protein (CP) levels for finishing pigs are an important area of research. Canh et al (1998) reported that nitrogen (N) excretion could be reduced through lowering CP levels and the aim of this study was to investigate the effect of decreasing CP levels of diets containing two levels of lysine (while maintaining the ideal protein balance through amino acid supplementation) on nutrient digestibility and N balance.
