ABSTRACT Broiler carcass skin color is important inthe United States and Mexico. This study evaluated theuse of natural and synthetic pigments in broiler diets atcommercial levels. Birds were fed natural or syntheticpigments at low or high levels, simulating US and Mexican commercial practices. Skin color was measured during live production (3 to 7 wk of age) and after slaughterand chilling. The natural pigments had consistentlygreater skin b* values (yellowness) than the syntheticpigments. The high levels produced greater skin b* valuesthan the low levels, regardless of source. The syntheticpigments had a slower increase in skin b* but reachedthe same level as the natural low by 7 wk.
