Abstract: An experiment was conducted to compare the metabolism of zinc from zinc methionine (ZnMet) chelate by 10 healthy goats which were divided into two groups fed with basal diet plus ⁶⁵ZnMet and ⁶⁵ZnSO₄,respectively.The results showed that the ⁶⁵Zn concentration in feces was lower in⁶⁵ZnMet group than in⁶⁵ZnSO₄ group.The absorption of zinc from ⁶⁵ZnMet was 49.12%,significantly (p<0.05). higher than that from ⁶⁵ZnSO₄(38.91%) The excretion of zinc came to a climax after 52 hours in ⁶⁵ZnMet group,18 hours later than that in ⁶⁵ZnSO₄ group. The remaining rates of ⁶⁵Zn in goat bodies were 40.38% in⁶⁵ZnMet group and 29.52% in ⁶⁵ZnSO₄ group. There was no significant difference in remaining rates between the two groups after stopping ⁶⁵Zn feed for 3 days. In whole experimental period and in both groups,the zinc content in unit gram of liver,spleen and pancreas was higher than that in other tissues and organs,and the lowest was found in unit gram of bone and hoof.
