[QUOTE="heiferhoney, post: 39200, member: 524"] Ollie, It's going to take me a few days to get the data. It comes from the University of Mississippi if memory serves me right and was a strict study of 3000 head of grass fed beef. They were developing an ultrasound program to determine which cattle could meet a grass fed beef program. All cattle were ultrasounded and killed to verify the ultrasound data. There are many criteria that they must meet at a maximum of 26 months of age. Carcass weight must be 550-975 lbs Fat cover at 45 days prior to harvest must be a minimum of 0.2 inches Actual ribeye area must be a minimum of 10.0 Minimum percent intramuscular fat must be 3.5% Tenderness score of 2.5 or less I don't remember which criteria they didn't meet. But enough of them did not meet it to warrant using them in this program. I am sure there are some charolais that can but the program is geared towards stock where most will meet it or it wouldn't be advantageous for them to travel to ultrasound them. I suggested this program to our guest poster because they mentioned they were in PA and this program is up and running and PA producers are needed/wanted. It was nothing personal, just what the program requires and some recent experience I had with a few head of charolais. I am not trying to start a breed battle. [/QUOTE]
