The effects of feeding high levels of cu and Zn to broiler chicks on performance of chicks mineral concentrations of serum and tissue were evaluated. Fifty chicks were allotted to each of five groups(the control standard<8ppm Cu and 40ppm Zn>:
150pm Cu:
300ppm Cu: 150ppm Cu: 150ppm plus 400ppm Zn: or 300ppm Cu plus 400ppm Zn) to receive one of the practical diets supplemented with copper sulfate and zinc oxide. Five chicks per treatment were allotted for metabolism trial and throughout analysis.
@ES The results obtained were summarized as follows:
@EN 1. Serum Mg concentration of chicks fed the diet with Cu+Zn did not significantly reduced in the 6-week experiment but significantly reduced(P<0.05) in the 3-week experiment. Serum Fe and Cu concentration of chicks fed the diet with 300ppm Cu
were
significantly increased (P<0.05), but they were reduced when Zn was added to the diet. According to this result, an additional effect between Cu and Fe and an antagonistic effect between Zn and Mg, Zn and Cu, and Zn and Fe were found out.
2. Mg concentration in liver of chicks fed the diet with Cu+Zn significantly reduced(P<0.05), while the Zn concentration of chicks significantly increased(P<0.05). Fe and Cu concentrations in liver of chicks fed the diet with 300ppm cu were
significantly increased (P<0.05), but they were reduced by adding Zn to the diet, According to this result, an additive effect between Cu and Fe and a competitive antagonism between Zn and mg, Zn and Cu, and Zn and Fe were found out.
3. Ca,Mg and Zn concentration in kidney of chicks fed the diet with Cu or Cu+Zn were not significant. Fe concentration in kidney of chicks fed the diet with 300ppm Cu significantly increased(P<0.05) in the 3-week experiment. Cu concentration in
kidney
of chicks fed the diet with Cu or Cu+Zn did not significantly different.
4. Ca, Mg, Zn and Fe concentrations in femoral muscle of chicks fed the diet with Cu or Cu+Zn were not significantly different. Cu concentration in femoral muscle of chicks fed with cu or Cu+Zn significantly increased(P<0.01).
5. Ca, Mg and Zn concentrations in femur of chicks fed on Cu or Cu+Zn were not significantly different. Fe and Cu concentrations in femur of chicks fed the diet containing 300ppm cu significantly increased(P<0.05) but those of Fe and Cu were
reduced by
adding Zn to the diet According to this result, an additive effect between Fe and Cu and an antagonistic effect between Cu and Zn, and Zn and Fe were found out.
