Beef is characterized by a high and uncontrolled variability of its quality which is one reason for the dissatisfaction of consumers. Therefore, the beef industry is asking for muscular markers to predict the ability of animals to produce high quality beef. Thanks to the development of genomics, some recent research allowed the identification of markers for muscle growth potential of bovines, for marbling and tenderness of beef and for traceability of grass-based systems. New tools (DNA or protein chips) are in development to assess a great number of these markers simultaneously.

Jakość wołowiny może być bardzo różna i jest trudna do kontrolowania, co często bywa przyczyną niezadowolenia konsumentów. Dlatego przemysł mięsny chętnie widziałby opracowanie genetycznych markerów pozwalających na wczesne wytypowanie zwierząt – producentów wołowiny o wysokiej jakości.Dzięki najnowszym osiągnięciom genomiki możliwa jest obecnie identyfikacja markerów dla takich cech jak rozrost umięśnienia, zawartość tłuszczu śródmięśniowego (marmurkowatość), kruchość mięsa, a nawet markerów do identyfikacji mięsa pochodzącego od zwierząt chowanych w systemie naturalnym (pastwiskowym). Opracowywane są nowe narzędzia, oparte na technikach microarray, umożliwiające równoczesne oznaczanie wielu takich genetycznych markerów u wybranych zwierząt dla oceny ich wartości hodowlanej pod względem jakości wołowiny.
