 Overall, the number of hogs weighing less than 180 pounds is about 1.5% larger than a year ago, which will be the market hogs arriving at processing plants from July through November. The year-over-year increase in lighter-weight hogs partly reflects the larger March through May pig crop, which itself results from a continued trend of growth in pigs per litter, here 1.75% higher than a year ago, outpacing reductions to farrowings at just 0.1% lower.
