摘要：

The aim of the study was to determine the influence of Cu-glycine chelate on the chemical composition of the liver and blood parameters of broiler chickens. A total of 250 one-day-old Ross 308 male chicks were allotted into 5 groups with 5 replicates of 10 birds each. Rearing of birds lasted 42 days. In the experiment Cu was added to the premix in the form of CuSO4 (16 mg, 8 mg Cu), and in the form of Cu glycine chelate (16 mg, 8 mg, 4 mg Cu). The parameters in the chickens' blood remained within the range of physiological norms when lower levels of the analyzed elements were added. Adding lower levels of Cu (8 or 4 mg.kg(-1)) in comparison with the recommended doses (16 mg.kg(-1)) for broilers, in the form of highly assimilable organic sources, did not reduce the content of minerals Cu, Fe, and Zn in the chickens' liver, but reduced the faecal Fe, Cu and Zn concentrations compared to CuSO4.
