    The effect of humic acids on lead accumulation in chicken organs and muscles

  • Original language description

    Control group (K) was fed without supplementation. The second group was fed the diet with humic acid (HA) in the dose of 500 mg/chicken/day. Experimental group 1 (Pb) was fed basic diet containing lead acetate in the dose of 3.54 mg (1.42 mg Pb) per pullet/day and the second experimental group (Pb + HA) was moreover fed 500 mg HA/day. The lead content was determined in the samples of liver, kidneys, bones and muscle tissue. The lead concentrations in the mentioned tissues were 4%, 12.6% and 10% of the highest admissible amounts (0.5 and 0.1 mg Pb/kg), respectively. In the experimental group of chickens (Pb), significantly increased lead concentrations were detected in liver, kidneys, bones and muscles. The highest accumulation was found in bones (2.711mg/kg). Concurrent administration of HA and lead acetate (HA + Pb group) caused a significant decrease in the Pb content, i.e. by 30%, 43.8 %, 53.8 % and 50.6% in liver, kidneys, muscles and bones, respectively, in contrast to experiment

    Vliv kyseliny huminové na ukládání olova v orgánech a svalovině kuřat

  • Czech description

    Kontrolní skupina (K) přijímala bazální dietu bez suplementace. Druhá skupina byla krmena bazální dietou s huminovou kyselinou (HA) v dávce 500 mg per chicken/day. První pokusná (Pb) přijímala s bazální dietou octan olovnatý v dávce 3.54 mg (1.42 mg Pb)na kus /den a druhá pokusná skupina (Pb + HA) navíc denně přijímala 500 mg HA. Ve vzorcích jater, ledvin, kosti a svalové tkáni byl stanoven obsah olova. V uvedených tkáních koncentrace činily pouze 4 %, 12.6 % a 10 % nejvyššího přípustného množství (0,5a 0,1 mg Pb/kg). V pokusné skupině kuřat (Pb) byly zjištěny vysoce průkazně zvýšené koncentrace olova v játrech, ledvině, kosti a ve svalovině. Nejvyšší kumulace byla zjištěna v kosti (2.711 mg/kg). Současná aplikace HA a octanu olovnatého (HA + Pb skupina) snížila signifikantně obsah Pb v játrech o 30 %, ledvině o 43.8 %, svalovině o 53.8 % a v kosti o 50.6 % ve srovnání s pokusnou skupinou Pb.
