Three hundred healthy one-day-old Avian broiler whose weight was similar to each other were selected, then they were divided into 5 disposals randomly, 3 repeats in each disposal. Adopting single factor design to compare the effect of chelate amino microelement (Fe, Cu, Mn, Zn) on production performance, death rate and disease occuring rate in leg of broiler. The results showed that the model of high level Cu advancing the growth of swine was not fit with broiler, The low level (0.5 times NRC level) was more propitious to exert the nutrition domino offect of chelate amino acid microelement.
