Sažetak
The aim of this study was to investigate lead content in components of feed products and mixed feeds for poultry in Bosnia and Herzegovina, and to compare obtained results with current local legislation on livestock feed and European legislation (RB&H 2/92 and EC/29/1999). During the years 2003-2004 lead content in feeds of plant, animal and mineral origin and mixed feeds for poultry were investigated. A total of 123 samples were collected including 61 plant feeds, 15 animal feeds, 20 mineral feeds and 27 samples of mixed feeds for poultry that were produced at feed factories in Bosnia and Herzegovina. Chemical analyses were performed in the laboratory at Department of Animal Nutrition of the Veterinary faculty of the University of Sarajevo. Lead content was determinated by flame atomic absorption spetrophotometry according to the AOAC. The obtained results were calculated to 88% of dry matter and statistically analyzed. Mean values of lead (mg/kg) in plant feeds were: corn grain 0.469, wheat grain 0.569, alfalfa meal 3.152, wheat meal 1.332, soybean meal 1.652 and sunflower meal 1.808 ranging from 0.354 to 4.006. Feeds of animal origin contained lead (mg/kg) as follows: yeast 3.322, fish meal 5.899 ranging from 2.113 to 7.036 and in mineral-feeds, limestone 7.579 and dicalcium phosphate 13.700 ranging from 12.480 to 20.270. Mean value of lead content in mixed feeds for poultry was 3.315 mg/kg ranging from 1.542 to 7.504 mg/kg.
