CHICAGO, June 19 (Reuters) - U.S. wheat futures climbed nearly 3 percent on Wednesday, their biggest daily rise since April, on buying and expectations of domestic demand for wheat as livestock feed, traders said. Corn and soybeans also advanced, led by new-crop contracts as forecasts for hotter, drier weather later this month in the U.S. Midwest raised concerns about potential crop stress. At the Chicago Board of Trade, July wheat settled up 19.5 cents, or 2.8 percent, at $7.07 per bushel. July corn ended up 9 cents at $6.82-1/4 a bushel, with new-crop December up 20 cents at $5.70-1/2. July soybeans rose 12-1/4 cents at $15.23 a bushel and new-crop November ended up 21 cents at $13.10-3/4.
