GeneSTAR Marbling and Tenderness Markers are DNA diagnostic tests for major genes identifying marbling and tenderness in beef cattle.

These tests like all DNA science are highly accurate and eliminate guesswork.

Producers can use the results of the tests to increase the marbling and tenderness potential of their herds. Thereby improving their carcass quality.

At Michaelong it is our long term objective to breed cattle that bring consistency to the eating quality of BEEF for the consumer. To do this producers should select for both marbling and tenderness by using desirable animals in their respective programmes.

All producers who consider the above together with other objective information, such as Fertility, Structure, Temperament and Yield should carry on a profitable breeding concern and produce “Better Beef for Butchers”.
