STUDY ON THE INFLUENCE OF SEX AND BREED ON BOVINE MEAT QUALITY

摘要

The purpose of this study is to analyze the variations in chemical composition of two muscle groups collected from three bovine breeds. The biological material was represented by the Gluteus and Semimembranosus muscles collected from bovine of Fleckvieh, Pinzgauer and Black spotted Romanian breed. The average protein content from Gluteus muscle ranged between 21.46% at the muscle collected from the Pinzgauer females and 21.83% at the males from the same breed. The average lipid content in Gluteus muscle has been above 2.0% in all breeds. The Semimembranosus muscle presented a minimum average protein content of 21.75% at the muscle collected from Black spotted Romanian breed and a maximum of 21.84% at Pinzgauer breed. The lipid content from Semimembranosus muscle varied between 1.85% at the Black spotted Romanian males and 2.50% at Fleckvieh breed. For both muscles there have not been obtained significant differences for the two parameters studied according to the sex of the animal. The breed has influenced the lipid content from the Gluteus muscle collected from females. Analysis of chemical composition of meat revealed the influence of sex, race, anatomical positioning of the muscle. Meat obtained has a poor quality, which revealed the need of refurbishment of these animals before slaughter.
