Metals profile in blood plasma, muscle and liver of Egyptian Baladi bulls and Friesian x Baladi bulls

Abstract EN

The present study was aimed to quantify the (selenium, zinc, lead and cadmium) metals in blood plasma, muscle and liver in Egyptian Baladi bulls and friesian x Baladi bulls.

the metals were determined by using atomic absorption (aa) flame spectrometry techniques.

the overall mean content of selenium in blood plasma, muscle and liver of Egyptian Baladi bulls and Friesian x Baladi bulls was 0.044±0.019mg/l, 0.170±0.027, and 0.39±0.17, mg/kg, respectively, while content of zinc was 0.81±0.14 mg/l, 33.5±5.5 and48.2±12.4 mg/kg, respectively.

the toxic elements lead and cadmium in blood plasma, muscle and liver of Egyptian Baladi bulls and Friesian x Baladi bulls was 0.01±0.01, 0.0008±0.0001mg/l, 0.06±0.01, 0.0049±0.0023 and 0.351±0.14, 0.277±0.1 mg/kg, respectively.

the correlation between selenium and cadmium concentration in blood plasma of Egyptian Baladi bulls was negative (p < 0.05) (r= - 0.82) and crossbred bull was (r= - 0.24), respectively.

positive correlation (p < 0.05) between zinc and cadmium concentration was observed in Egyptian Baladi bulls and Friesian x Baladi bulls (r= 0.66) and (r= 0.95), respectively.

the present investigation demonstrates that the level of cadmium was decreased as plasma selenium concentration was increased and the correlation between selenium and cadmium concentration in blood plasma of Egyptian Baladi bulls was higher (p < 0.05) and negative(r= - 0.82) than crossbred bull(r= - 0.24).

the positive correlation between zinc and cadmium concentration in blood plasma Egyptian Baladi bulls and Friesian x Baladi bulls (r= 0.66) and (r= 0.95), respectively.
