Feeder cattle futures strengthened due to weakness in the grain market and efforts to encourage ranchers to rebuild their herds, while live cattle futures decreased due to profit-taking and weaker-than-expected cash trades. Severe winter weather impacted the cattle slaughter rate and temperatures in the Northern Plains, affecting both beef and pork processing. Lean hog futures were mixed, with traders reconsidering the wide spread between February and June contracts and the impact of a larger than expected inventory of all hogs and pigs reported by the USDA.
