EFFECTS OF AGE, SEX AND BREED ON BIOCHEMICAL BLOOD PARAMETERS OF CATTLE AT SLAUGHTERHOUSE

Ancuţa Elena Prisacaru

Abstract
    The aim of this study was comparison of blood biochemical parameters according to age, sex and breed in cattle. Blood samples from 33 Fleckvieh, Pinzgauer and Black Spotted Romanian breed at different age (less and more than 2 years), sex (male and female) were taken, transported to the analyzing laboratory, serum was obtained and analyzed with "Accent 200" blood analyzer. The biochemical parameters analysis (total protein, albumin, triglycerides, cholesterol, glucose, uric acid, urea, amylase, aspartate transaminase, alanine amino transferase, alkali phosphatase, calcium, inorganic phosphorus, magnesium and iron) leads to the metabolic and functional interpretation of the physiological status before slaughter with consequences on meat quality. The values obtained were statistically analyzed; the mean and standard deviations were calculated. The obtained results lead to a biochemical characterization of the blood biochemical indicators, highlighting the differences between the breed groups and allow the possibility of metabolic status interpretation through the presented values dynamic.
