Grains end lower to start the week, with livestock higher.  Allison Thompson with The Money Farm says pressure in the grains came from a lack of news or fresh demand, farmer selling and bearish outside markets like lower crude oil and a higher dollar.  Wheat was also down with improved weather and made new lows for the move before finding technical support.  Cattle futures also made new lows before bouncing and ending in the green but is it a one day blip?
