VALORES HEMATOLÓGICOS EM FRANGOS DE CORTE DE CRIAÇÃO INDUSTRIAL

The use of hematology is an important tool for establishing the diagnosis of various diseases and for understanding the mechanisms of pathogenesis of them. In Brazil there are few references on avian hematologic values and on the factors that can influence these parameters. In view of these issues, the aim of this work was the determination of hematological values of broiler males, commercial line, reared in the industrial system, between 7 and 42 days of age, where normally the birds are slaughtered. The results showed that the total number of red blood cells (Hm) was between 1.69 and 2.03 X 106/μL and packed cell volume (PCV) between 29.6 and 33.2%. Hemoglobin level between 8.26 and 10.38 g/ dL. The total number of leukocytes varied between 11900 and 18,500 X 103 /μL. However, variations in the values of these parameters between the different age groups were not considered significant (p <0.05). The conclusion of this work that there is a need for more research in the area in order to better establish themselves discuss hematologic values of reference for broiler chickens in Brazil
