Grains end mixed with soybeans seeing corrective buying following soybean meal, while corn ends lower, wheat mixed.  Shawn Hackett, Hackett Financial Advisors, says corn and beans took out March lows and are oversold and could see some short covering into the end of the quarter and before the USDA reports.  Cattle futures see bull spreading with record cash verses bearish COF placements. Hogs again hit new contract lows following cash.
