Contamination of bovine insemination doses, used for artificialinsemination, with cadmium, copper, lead and zinc as well as itsrelation to semen activity was investigated. Analysis by atomicabsorption spectrophotometry(AAS)of cadmium showed that the averageconcentration was 0.0058 mg/kg. The concentration of copper was inthe range of 0.2-1.0 mg/kg with the average value of 0.515 mg/kg.Contamination of bovine insemination doses reached the average valueof 0.310 mg/kg And the concentration of zinc reached 6.5-14.2 mg/kgwith the average level of 8.645 Mg/kg.
