Chicago Mercantile Exchange live cattle futures closed lower on Monday, weakened by sell stops and uncertainty regarding cash prices later this week, traders said.
Funds that track the Standard & Poor's Goldman Sachs Commodity Index at times sold, or "rolled", August futures and simultaneously bought October on the first of five days of the Goldman Roll process.
August ended 0.950 cent lower at 113.825 cents, and October finished down 0.400 cent to 113.425 cents.

July, which will expire on July 17, ended down 0.250 cent per pound to 91.475 cents. Most actively-traded August finished 1.225 cents lower at 82.000 cents.
