Live cattle futures saw choppy to higher trade early in the session but a set-back in grain markets and renewed optimism that the cash cattle market may show some additional strength this week helped to support sharply higher trade into the mid-session. A break in the US dollar, a more positive tilt to the economic outlook and a firming tone for beef prices helped to support. Boxed-beef cut-out values were up 41 cents at mid-day to $178.55 from $177.62 last week at this time.
