[QUOTE="dph, post: 220477, member: 2112"] I too disagree with Mike's assessment that they can't prove the validity of the tenderness genes. All studies I have seen, prove a reduction in shear force with an increasing number of genes. What is interesting to note is that Bovigen also markets a differnet tenderness gene in Austrailia because it only seems to have an impact on grass feed beef. The have also identified a tenderness gene that seems to be absent in exotic breeds and very prevalent in the domestic (?) ones. The marbling genes also seem to have been proven out the same way. Though I think they have a lot farther to go there. There are many genes yet to identify. But one could also argue, even with some genes currently being unknown, it's better to have the known ones than not. Right, it will take awhile to get there. But I think once they get there, they will get there in a hurry. How long will it take a producer to breed these genes in your herd? We simply use them as a selection tool. Phenotype the most important, then taking a look at acceptable EPDs, then taking a look at the gene test. I think the program will follow how the CAB program came about. [/QUOTE]
