Abstract
Interpretation of the physiological status of bovines by means of blood biochemistry gives us information about the animal, the husbandry and maintenance technologies used, whose consequences are reflected on meat quality. The purpose of this study was to analyze the protein blood profile and muscle proteins in bovines. The research material used was represented by bovines, belonging to races Fleckvieh, Pinzgauer and Black Spotted Romanian, which were slaughtered for sale as cut portions. From these animals blood and muscle samples were taken. The muscular tissue was represented by Longissimus dorsi, Semimembranosus, Triceps brachii, Rhomboideus muscle. The concentration of total blood proteins ranged from 9.38 g/dL in Pinzgauer females and 12.99 g/dL in Fleckvieh females. Blood albumin showed values of 5.53 g/dL in Fleckvieh males and 3.37 g/dL in Black Spotted Romanian females. Muscle protein content was higher at the Black Spotted Romanian race, both males and females, in the Triceps brachii and Rhomboideus muscles. The analysis of the obtained values indicates that at the bovines with high concentrations of total blood protein and albumin had a lower percentage of muscle protein.

Key words: bovine, total blood protein, albumin, muscle tissue, muscle proteins
