Effects of Different Zinc Sources and Levels on Growth Performance, Serum Antioxidant Indices and Utilization of Trace Elements of Growing-Finishing Pigs
This experiment aimed to evaluate the effects of lowlevels of zinc methionine(Zn-Met) or zinc sulfate(ZnSO_4) on growth performance,serum antioxidant indices and utilization of trace elements to determine the appropriate level of zinc in diets for growing-finishing pigs,so that realize the high efficient utilization of resources,and reduce the environmental impact of zinc in excreta. Thirty-two growing-finishing pigs(Duroc×Landrace×Largewhite) with average weight of(33.70 ± 2.76) kg were randomly divided in...
