U.S. hogs futures also succumbed to the outside market pressure. Traders are watching for signs that demand is rebounding after sharp losses last month.

Lean hog futures for June settled 0.25 cent, or 0.3%, lower at 93.22 cents, while the July contract ended 0.45 cent, or 0.5%, lower at 93.42 cents. The May contract ended nearly flat at 92.02 cents in thin trading volume ahead of Friday's expiration.

In the cash hog markets, prices were expected to be mostly steady with a few firmer quotes for loads to arrive next week. Seasonally tighter supplies and some processors seen needing additional hogs for their Memorial Day holiday orders fueled firmer price expectations by some analysts and livestock dealers.

The terminal markets traded steady to weaker with top prices at mostly $61 per hundred pounds on a live basis.

The latest Dow Jones Newswires pork packer margin index was plus 68 cents per head, compared with minus 64 cents the previous day.

The USDA's pork carcass composite value, a measure of wholesale prices, for Tuesday was $91.80 per hundred pounds, up 89 cents.
