The best market comparison from last week's much smaller sale, was Heifers, 850-1000lbs, 8.00-10.00 higher. The market was active for today's offering of mostly open heifers and spring born calves. Shots on spring calves were mixed, with some carrying both spring and fall, and others with just spring. Several load lots and large packages were offered from producers coming to town a little earlier than usual because of drought conditions. However, some of today's offering had some tagg from the much needed rain in the area overnight. Demand was good for both calves and yearlings, with a lot of the regular buyers back in the seats for the opening of fall run.

What does "Medium and Large 1" mean?

USDA feeder grades describe frame size and muscle thickness, not quality of the individual animal. "Medium and Large" is the frame score; the number is muscle (1 = heaviest muscled). "Medium and Large 1–2" pens mix both muscle scores — common across the Southeast.

What is $/cwt?

Dollars per hundredweight — per 100 lb of animal. A 500-lb calf at $450/cwt brings 5 × $450 = $2,250. Lighter cattle usually bring more per cwt but less per head.

Why are some prices per head?

Bred cows, cow-calf pairs, and some replacement classes sell by the head, not by weight. We show those exactly as USDA reports them — a $/head figure is never converted into $/cwt on this site.

Where do these numbers come from?

From the USDA Agricultural Marketing Service's Livestock Market News — federal reporters at the sale. We publish each report in full and link the official USDA document at the top of the page.
