KANSAS CITY (Dow Jones)--This week's fed cattle trading in the Plains is just about done Friday morning after a late flurry of activity Thursday.

Market analysts and brokers said cattle feeders in Nebraska were aggressive sellers this week, moving as many as 85,000 head in a general range from $129 to $131 per hundredweight on a dressed basis, with most at $130 to $131. On a live basis, Nebraska feeders generally sold from $83 to $84.

In Kansas, market analysts and brokers said they could account for 22,000 to 23,000 head being sold but say there likely were more that will be counted on Friday. Prices ranged from $84 to mostly $84.50, although to get the higher price, many feeders had to allow packers extra time to remove the cattle from the lots, the analysts and brokers said.

The story was similar in the Texas/Oklahoma area where an estimated 25,000 to 30,000 head traded at mostly $84.50 with the extra time included. Market analysts also expect to find that more cattle traded than they know about early Friday.

Cattle owners in Kansas, Oklahoma and Texas had been holding out for higher prices, but packers appear to have access to plenty of cattle to feed their modified slaughter schedules, a trader said. This is a problem for cattle feeders trying to wrest a little more out of the market to get them into profitable territory, he said.

The U.S. Department of Agriculture Thursday reported its choice boxed beef cutout price at $141.69 per hundredweight, down $0.65, while select beef was off $0.25 at $134.16. The volume of fabricated loads was 241 and there were 84 loads of trimmings and coarse grind product reported.

The HedgersEdge packer margin index is a plus $16.30 a head, compared with the previous index of a plus $14.45. For the week, the index is a plus $13.95.

Urner Barry's Yellow Sheet Thursday said boxed beef markets remained mostly steady. Chucks were mostly stead, rounds were soft, and middle meats were about steady. Trim values were lower.
