Which breeds are eligible for MSA grading?
All breeds of cattle are eligible for MSA grading, although Bos indicus or tropical breed content (TBC) as a single attribute can have up to 12% variation on eating quality. Generally as tropical breed content increases, eating quality decreases.
Tropical Breed Content (TBC)
MSA research has shown that the tropical breed content of cattle (Bos indicus) has a negative impact on the eating quality of many cuts. The negative effect is most evident in those cuts with little connective tissue and is primarily associated with differences in enzyme action within the muscles between Bos Taurus and Bos indicus breeds.
The hump on the carcase will also be measured to validate tropical breed content.
On-farm management of genetics and nutrition will maximize eating quality of beef from tropical breed cattle.
Do I need to declare the tropical breed content of my cattle?
Producers are to declare the tropical breed content of their cattle on the MSA vendor declaration by ticking the most appropriate box that describes them.
