These diets contained 4·5 to 6·1 g threonine per kg and were supplemented with graded additions of synthetic L-threonine. It was found that the amount of threonine required for maximum performance and nitrogen retention was 6·6 g/kg dry matter (DM) between 7 and 28 days of age and 5·4 g/kg DM between 28 and 56 days of age. These values were calculated to correspond to 0·43 and 0·36 g threonine per MJ digestible energy. The concentration of threonine in the blood plasma did not give a clear indication of the threonine requirement of the pigs.
