Abstract

Eight dietary levels of threonine ranging from 4·8 to 6·6 g/kg air-dry diet were given to 64 growing female pigs from 25 to 55 kg live weight. Results for daily live-weight gain and food conversion ratio indicated a requirement value for dietary threonine of 5·6 g/kg. The pattern of response exhibited by blood urea suggested a requirement of 5·4 g/kg. No clear trends were found for carcass composition or plasma free amino acids
