Perfil hematológico e bioquímico sérico de gatos domésticos (Felis catus - Linnaeus, 1758), da raça Persa e mestiços

Abstract

The growing number of domestic cats (Felis catus) living in close relationship with humans, in the condition of animal companions, has led to a concomitantly increasing demand for new knowledge about the species, particularly about the hematological and serum biochemical parameters, which are important tools in the evaluation and monitoring of their health and their adaptation to the lifestyle imposed on them. In this context, the purpose of this study was to determine the physiological changes, and the influence of racial factors and of sex on the hematological and serum biochemical parameters of adult domestic Persian and half-breed cats. Analyses were made of the hematological parameters and 24 serum biochemical constituents of 106 adult domestic cats, over 24 months of age, males and females, 51 Persians and 55 half-breeds. With regard to the hematological parameters, it was found that the mean values of rod neutrophils of the half-breed cats and of eosinophils of both Persians and half-breeds were higher than the reference values for the species. The serum biochemical profile of the alanine aminotransferase (ALT) activity in the Persian cats and the concentration of urea in both Persians and half-breeds showed mean values exceeding the reference values reported in the literature. A comparison of the hemograms of the Persians and half-breeds revealed statistically significant differences in the values of their globular volume, mean globular volume (MGV), and number of basophils. As for the serum biochemistry, of the 24 elements analyzed, statistically significant differences were found in the mean values of very low density lipoproteins (VLDL), triglycerides, total proteins, albumin, globulins, ALT, alkaline phosphatase, phosphorus, Ca:P ratio, uric acid, and amylase between the Persian and half-breed cats. No significant difference was found between males and females in the values of the hematological of serum biochemical parameters analyzed. It was concluded that the breed, but not sex, influences the hematological parameters and the serum biochemical profile of adult domestic cats.
