[QUOTE="simme, post: 1772052, member: 40418"] Angus association has a lot of epd's. But I don't think they have one for tenderness (shear). Simmental has had one for years, but that epd usually has the lowest accuracy of any. I guess the accuracy is low because of the amount of data available. I think that shear/tenderness measurement involves measuring the mechanical force required to push a cutting edge through a piece of meat. Getting enough data points on enough animals to produce an accurate epd is probably difficult, time consuming and expensive. Who bears the costs for that test is probably an issue. Angus has an epd for scrotal circumference. Simmental does not have that one. I suspect each new epd requires quite an effort to develop. Collecting enough data on many animals in many locations, developing the model to calculate the epd values and the ongoing effort to collect and process data for that value in the future. I suspect it takes years to develop a new epd with enough accuracy and confidence to be valuable. I think the majority of people don't get beyond CE, BW, WW and MILK. [/QUOTE]
