Consultant Tracks Decline In Hog Slaughter WeightsConsultant Tracks Decline In Hog Slaughter Weights
He adds: “This year we’ve gone from the heaviest weekly live weights on record in January, February and March to falling within 1.2 lb. of the 2004-2008 average weekly weight for week 30 of the market year

Live weights in the past two weeks declined 5.7 lb., the largest drop in the eight-year dataset of Iowa/southern Minnesota barrow and gilt slaughter weights reported by USDA and tracked by Minnesota swine consultant Mike Brumm.
The only other decline similar was the 5.5-lb. drop in weights for the two-week period ending on July 4 in 2009.
“In 2009, weights went from 268.7 lb. for the week ending on June 20 to 263.2 lb. for the week ending on July 4,” he recalls. “This year, weights have fallen from 266.6 for the weeks ending on July 9 and July 16 to 260.9 for the week ending on July 30.”
He adds: “This year we’ve gone from the heaviest weekly live weights on record in January, February and March to falling within 1.2 lb. of the 2004-2008 average weekly weight for week 30 of the market year.
“We’ve gone from an average live weight of 275.8 lb. for the week ending Jan. 8 to the 260.9 weight last week, a reduction of 14.9 lb./pig delivered to slaughter plants. This is a 5.4% reduction in pork supplies just from a change in live weight, assuming constant carcass yield and similar pig numbers delivered both weeks.”
Brumm says some of the decline in sale weight is due to producer reaction to historic feed ingredient prices and recent record heat.
“In tunnel barns with very detailed records, I’ve seen over 0.1 lb./day difference in average daily gain between the curtain end of the barn where the highest daily gains occurred, and the fan end of the barn, which was the warmest part of the barn, even with fans running and pigs being wetted down,” he says.
