- Abstract
The aim of this research was to determine the trace element content (Pb, Cd, Cu, Cr, Zn and Fe) in liver, depending on the type of fat used in diets for broiler fattening. Four groups of Cobb 500 broiler chickens were used for the experiment. Each group had 60 broiler chickens. Broilers were fed with diets containing soybean oil, sunflower oil, beef tallow and lard. Broilers were fed with the starter mixture during the first sixteen days and with the finisher mixture from the 17th to 42nd day. The fat content in feed mixtures was 3% per treatment. Broilers were submitted to 12 hour pre-slaughter fasting time. After the slaughter, their carcasses were first cooled down to 4°C within 24 hours and stored at -18°C prior to the chemical analyses. Samples were taken randomly. The highest lead (Pb) concentration was recorded in liver samples of broilers fed with feed containing soybean oil and it was 0,042 mg/kg. The concentration of lead in samples of broilers fed with feed containing sunflower oil was 0,036 mg/kg, followed by lard (0,022 mg/kg), and beef tallow (0,019 mg/kg). Cadmium (Cd) content in broilers fed with feed containing soybean oil was 0,021 mg/kg, followed by sunflower oil (0,017 mg/kg), lard (0,013 mg/kg) and beef tallow (0,011 mg/kg). We can conclude that using animal and vegetable fat in broiler diets has affected the parameters of heavy metal content in broiler liver.
