Cattle futures are trading steady to mixed at midsession. Commercial buying and the more strength in boxed beef prices are supportive factors. But gains are being limited by ideas the market is topping. June is steady at $85.63.

Lean hog futures are higher this morning. Steady to higher cash hog prices and pork cutouts gains of $1 yesterday are supporting the market. Traders want to be long in anticipation of the seasonal decline in market ready hog numbers. June is 53 cents higher at $77.45.
