1026 ET - Live cattle futures are lower following Thursday's announcement from Tyson Foods of a closure of a beef plant, as well as selling another. Tyson pulling back from the beef business amid a stubbornly-small cattle herd appears to be injecting more pessimism into the outlook for cattle prices. "The bears have the clear edge and the market appears to be on track to retest last month's lows on technical weakness and lower cash trade," says the Hightower Report in a note. Most-active live cattle on the CME is down 0.8%, while lean hog futures are off 0.6%.
