This experiment was carried out to determine the threonine requirement for broilers chicks from 1 to 21 days of age and to evaluate the effect of different threonine levels on the uric acid excretion in broilers. One thousand and two hundred broiler chicks were randomly allotted to a 6×2 factorial arrangement, being six levels of total threonine (.73, .77, .81, .85, .89, and .93%) and two sexes, with five replicates of 20 birds each. Feed intake, weight gain, feed:gain ratio […]
