The heavy metals (Pb and Cd) accumulation in beef meat when using triticale and lupin in a diet

Abstract

The recipes of grain mixtures for young stock fattening in the third zone of radioactive contamination with different dosages of triticale have been developed. It has been determined that the Pb concentration in the produce was considerably less than the MPL hereby the content of Pb in the longest muscle of animals back in testing groups decreased by 0.004–0.055mg/kg or by 2.8–32% as compared to check analogies. When 29–40% (in mass) of grain chop is substituted by 20–40% (in mass) of triticale chop, the Pb concentration in liver also decreases by 11.8–13.1%. The level of beef meat and liver contamination by Cd was 9.8–14.6 and 2.3–3.1 times more than in the normative requirements. The concentration of Cd in meat and liver occurred to be the least in the second group of animals — 0.488 and 0.689 mg/kg correspondingly. In the bull-calves of this group the content of Cd in the longest muscle of animals back and in the liver was less by 24.3–33.2% and 21.4–25.4% correspondingly as compared to the analogies in other testing groups. The coefficients of Cd transition into beef-meat and liver were high — 18.8–29.9% and 26.6–40.7% correspondingly. The substitution of 20% (in mass) of grain chop for the same amount of triticale chop in a grain-mixture content when fattening the calves contributed to a considerably lesser transition of Cd into the production (18.8 and 26.6% that is lower than the analogical indexes in other groups by 9.6–11.1%, 9.3–14.1% correspondingly.
