Summary

Three treatments involving isocaloric diets with the same levels of lysine and methionine but different crude protein levels were imposed on pigs from 50 to 200 lb live weight. Significant treatment differences were obtained only during the period from 50 to 120 lb live weight when pigs on the 17% protein diet (barley+soya bean meal+white fish meal) had the fastest growth rates and best food conversion efficiencies and pigs on the 11% protein diet (barley only) were the poorest. Pigs fed barley alone also had the fattest carcasses.
