Abstract
Abstract The goal of this research was to evaluate egg quality and performance of laying hens at the second laying cycle, fed with minerals from an organic source. The  control treatment consisted of  basal diet with inorganic trace minerals, whereas the other treatments consisted of organic copper, iron, manganese, and zinc at levels of 100%, 90%, 80%, and 70%. Physical and chemical analyses were performed to evaluate egg quality. The average egg weight reduced in the test diet; however, egg mass, as well as the other performance variables evaluated, did not suffer influence of treatments. The percentage of egg protein decreased; however, mineral matter content...
