Comparative Studies Of Trace Element And Nitrite Contents In Chicken Feeded Antibiotics And Its Substitutes

To explore trace element and nitrite contents in chicken by breeding propolis, aloe and chlorotetracycline, respectively, we carried out this investigation. 600 broilers treated with three groups of composition were studied. The contents of 7 trace elements and nitrite were determined randomly, and carried out analysis of variance for the results. The contents of trace element (except Lead) and nitrite in three groups of chicken were all lower than the maximum limitation in livestock and poultry for meat in China (GB2001).The difference among three groups of chicken was not remarkable in statistics with one-way ANOVA (except lead). The lead contents within chicken fed with propolis were higher remarkably than that of other two groups ( mean: 0.208 mg/kg , GB:0.1 mg/kg). After using propolis and aloe as a substitute for chlorotetracycline, the contents of trace elements within chicken fed with propolis, aloe and chlorotetracycline have not remarkable difference. The Lead content within chicken fed with propolis had a very higher level of Lead. The propolis is not fit for replacing chlorotetracycline.
