Resumo
The Pantaneiro cattle reveal docility, resistance to illnesses and parasites, and an incredible ability to adapt to Pantanal's edophoclimatic conditions. The cattle may be used without considerable investment to explore low-quality natural pastures in which other breeds might endure low productivity or even survival difficulties. Thus the determination of the normal blood constituents of Pantaneiro bovines was set in order to reveal further information regarding the physiological aspects of these animals. Therefore 293 blood samples were collected from two rural properties, one from Mato Grosso and the other from Mato Grosso do Sul. These individuals were classified in five groups according to their age group, as follows: G1, G2, G3, G4, and G5. The parameters under investigation were the erythrogram and the leukogram. Initially the data was submitted to descriptive statistics which included the determination of averages, standard deviation, and coefficients of variation. Subsequently data was submitted to the Kruskall Wallis test in order to establish the age relationship and to the Mann-Whitney test in order to establish the sex relationship. Age advancement revealed an increase in MCV, MCH, and in the number of eosinophils. Age advancement showed a reduction in the number of red blood cells, hemoglobin, MCHC, segmented neutrophils, and band neutrophils. The values of globular volume and monocytes revealed a rising behavior up to 35 months of age and subsequently suffered a reduction as age advanced. The values of lymphocytes and total leukocytes presented a rising behavior up to 11 months of age and a subsequent decline as age increased. The results of this research failed to show any relations between hematological parameters and the sex factor
