Chicago | Reuters — U.S. live cattle futures notched new contract highs for the third consecutive session on Wednesday before the rally fizzled out.
Traders were searching for fresh news to push up prices after factoring in concerns about cold weather and snow in the central U.S. slowing weight gain in herds and disrupting shipments of livestock to processing plants.
The wintry weather fueled worries about a temporary tightening of supplies that helped lift prices recently.
During the weekend and early next week, a strong surge of cold air will engulf the Plains and Midwest, according to a forecast from the U.S. Department of Agriculture. Cattle typically do not gain weight as quickly in cold weather because they consume feed to generate body heat.
