IMF CCL6th progeny

[librarian]

Red bulls, I thought there was a post about ultrasound on a group on CCL6th sons and the IMF was over 5 on several. Do you have that information? I can't find the post.
Or do you think the high IMF came from the Dover breeding in the dams of most of those bulls?
I did find this about CCLth himself in one of your old posts:
I’ve long suspected that some of the older genetics may have marbled well and was not disappointed when, at 508 days, this bull had an actual Rib Fat measurement of .32 and his actual IMF was 4.89 on very low inputs.

Coalpit Creek Leader 6th has a very high marbling EPD of 0.32 putting him in the top 10%. There is an interesting calf at Fairview out of the 6th's full sister and by DMH Cherry Fillet (Fairview Cherry Red ET). Cherry Fillet is a by another son of the 21st, Weston Trademark 3rd and out of a cow with Haumont breeding. Some intersting line breeding with the marbling, calving ease and BW being in the very top of the breed.

Librarian,
Due to the high steer prices last year, I only kept 6 bull calves. For the most part, they were selected for the maternal qualities of their dams such as high fertility, soundness and udder quality with sufficient milk. They were also solid red, as that is what I am able to market best. My commercial customers here in the West prefer the solid red ones, so that's what I try to raise. I hope to get video of the heifer mates to the bulls I posted here under "Fall Season in the Bitterroot" soon, and will try to keep the much neglected website updated more frequently!

The six Coalpit Creek Leader 6th calves I kept last year wintered at the Nancy M. Cummings research center at Salmon, ID. It belongs to the University of Idaho. They are set up with the "Grow Safe" system so have the ability to measure Feed Efficiency. There were also two pens of Angus bulls there. The bulls were all fed the same high roughage diet consisting of about 70% chopped hay (last year's hay was not very good!) with the balance consisting of wheat midds and ground corn plus a mineral package. Our Shorthorn bulls were pretty much average for FE when compared to the entire population. The average on the six for ultrasound was .25 Rib Fat; 4.00 marbling. They averaged 1.23 inches of ribeye/100 lbs. We have 12 bulls there this winter. 5 are CPL 6th sons and 7 are YY Gus' Double 105U sons.

How did they compare to the entire population in fat, marbling, and ribeye?

Oakview, I would've liked to known also. The center will not share information between breeds/breeders. I think that's a good thing. I hauled the heifers about 15 miles last year to one of the participating Angus guys place to make it more convenient for the ultra sound tech. This Angus guy and I are pretty good acquaintances. I shared my bull scan data with him, but he didn't reciprocate. The heifer mates to the bulls also scanned an average of .25 Rib Fat; averaged 1.27 in./CWT for REA and were an average of 4.03 for %IMF. The heifers here never receive any concentrates and are fed grass hay on pasture only after weaning. I feel this explains the marbling similarity in that they were almost identical to the bulls.
