Abstract: We studied 104 buffaloes, adults, without distinction of race and sex, reared extensively, without supplementation, in native pastures of low nutritional quality, in the municipalities of Breves, Cachoeira do Arari, Salvaterra and Soure, Marajo Island, Pará. Held collection of liver, bone and blood of 26 animals in the municipality of Salvaterra, 38 animals in the municipality of Soure, 20 animals in the municipality of Breves and 20 animals in the municipality of Cachoeira do Arari. Determination was performed to determine the levels of phosphorus in the blood serum and bone ash and specific gravity on bone and cobalt, copper and zinc in liver tissue. It was observed that the average phosphorus concentrations in blood serum (6.26 mg/dl) and bone (10.77 %), the percentage of ash (60.87 %) and specific gravity (1.59 g/ml) of bone were lower than the critical levels established for cattle, characterizing phosphorus deficiency. The average concentrations of copper (5.57 ppm) and zinc (27.05 ppm) was considered low when compared with reference values, characterizing disability for these elements. In the case of cobalt when considering the values detectable and undetectable by the methodology it was observed that 51.92% of the animals had levels below the reference, indicating the occurrence of cobalt deficiency in these animals. It is emphasized that the deficiencies of copper and zinc showed a more severe since all animals studied showed low levels of these elements.
