Corn futures are higher at midday. Light speculative buying has helped extend the strong gains posted on Tuesday. Strong demand continues to come from export demand, feed use, and the ethanol industry. Rain in the eastern Corn Belt is expected to further slow the tail end of harvest. December is 5 1/4 cents higher at $3.63 and March is 5 1/2 cents higher at $3.77.

Soybean futures are higher at midday. The market has been choppy as profit-taking briefly pushed prices lower. But prices rebounded on spillover support from corn and bullish technical momentum. January is 3 3/4 cents higher at $6.75 and March is 3 cents higher at $6.87 1/2.

Wheat futures are trading higher at midsession. Follow-through buying from yesterday's technical reversal and spillover strength from corn are supporting the market. Dry weather in the Plains and too much precipitation in the eastern Midwest are supportive fundamental factors. CBOT Mar is 7 1/2 cents higher at $5.13 1/2, KCBT Mar is 6 1/2 cents higher at $5.38, and MGE Mar is 3 1/4 cents higher at $5.19 1/4.

Cattle futures are trading higher at midsession. The market is finding support from firming boxed beef values and ideas that Friday's Cattle on Feed report will show October placements down and marketings up. Gains are being limited by reports of some scattered cash trade at lower levels. December is 33 cents higher at $86.18 and February is 28 cents higher at $88.68.

Lean hog futures are lower at midday. Further weakness in the cash market is weighing on futures. Packer demand for hogs has been light this week as slaughter schedules have been trimmed. Fund selling has extended the losses once futures fell below support levels. December is 78 cents lower at $60.90 and February is 53 cents lower at $64.15.
