CHICAGO, Nov 17 (Reuters) - Chicago Mercantile Exchange live cattle and feeder cattle futures ended higher on Friday as livestock traders adjusted positions in the markets.

After the close of trading, the U.S. Department of Agriculture issued monthly data that showed producers placed 3.8% more cattle into feedlots in October than a year earlier, below analysts' expectations for a 4.9% increase.

Lower-than-expected placements may support futures prices next week, though money flows and positioning ahead of the U.S. Thanksgiving holiday could overrule supply factors, analysts said.

Cattle weighing more than 700 pounds in feedlots signal the sector will be well supplied early next year, when the animals will become heavy enough to be slaughtered, said Altin Kalo, agricultural economist for Steiner Consulting. Supplies may not be as large heading into April, May and June, he said, signaling tightness for the sector.

"We have a total supply on feed that is a little bit front heavy," Kalo said.

The USDA said there were 11.9 million cattle on feed for the slaughter market on Nov. 1, up 1.7% from a year earlier. That was close to analysts' expectations for a 1.8% increase.

Cattle marketings in October were down 2.5% from a year ago, compared to analysts' estimates for a decline of 2.1%.
