Cattle prices across the board continued their upward climb last month, enough so to keep the majority of Drovers' index of economic indicators pointing up. Five out of eight arrows point up with two sideways and one down. The only downward indicator reflects lower performance, higher cost of gain and smaller feeder margins. However margins do remain positive. Boxed beef and average retail beef prices were higher last month, pulling cattle and calf prices up as well. Fewer cattle on feed, higher marketings and lighter carcass weights indicate a smaller beef supply in the midst of growing demand. However feeders will have to work hard to remain current as a large supply of cattle placed against the summer months move to market. Analyst predict fed prices will decline into the upper $60s due to such heavy supplies.
