Last week, I was asked by 2 different clients for data on the productivity of the US breeding herd. In reply to their question I went back and looked at data from the quarterly USDA Hogs and Pigs report.
I reviewed the data from June 1 thru May 31 for the 1992-93, 2002-03 and 2012-13 periods. I also reviewed the data from the PigCHAMP record system annual production summary for US cooperators.
For 1992-93, U.S. producers reported a pig crop (pigs weaned) of 13.6 pigs per average animal in the kept for breeding category. This increased to 16.8 for the 2002-03 period and increased again to 20.3 for the 2012-13 period.
