The basal diet was formulated with corn and peanut meal to contain 1.00% dietary lysine and .40% dietary threonine. Sucrose was replaced by synthetic threonine to give dietary threonine levels of .50, .60, .70, and .80%. Two pigs were housed per pen for a total of six pens per treatment (12 pigs per treatment). Pig weights and feeder weights were recorded weekly to determine ADG, ADFI, and feed efficiency. On d 14 …
