[QUOTE="dun, post: 7548, member: 34"] Ulstrasound, etc., are not near as common. Part of the reason is the expense of having them read by a qualified techician. Kill data is used to generate EPds, but they're a small part of the equation. If the data is collected, that's the way carcass EPDs are updated. So few carcass data are available and submitted, thats' the reaon that a bull may have an accuracy for BW of .99 and carcass EPDs in a lower accuracy. We used two bulls that have nearly identical but low accuracy for carcass, data and one has a much lower BW EPD with about the same accuracy as the other. Their calves pretty well matched up with their other traits, but one bulls calvs marbled high choice, the others were middle select. The calves from the select bulls are really magnificent. When we had a feed lot tour they pointed those calves out as the kind that would be moneymakers. Turns out the other bull, while not as impressive on the hoof were really impressive on the rail. We get back carcass data and ADG data, feed conversion data, etc. If we submitted the carcass data it would be applied toward the carcass EPDs. It costs us about 3 bucks a head to get all the data, it would cost a bunch more to get ultrasound on them. We just use the data for our own information when selecting bulls to be bred to specific cows. Babbled long enough dun [/QUOTE]
