Abstract
In The Beginning
The first recorded evidence of swine performance testing started in Denmark in 1907 and since then has
operated continuously except for three years during World War I when a shortage of feed forced the
suspension of all testing. In those early days only swine bred at organized swine breeding centers were
eligible for registration because those were the farms where breeders had complied with certain regulations
including sending each year to the testing stations half as many litters as they had sows in their herd. At the
test station these test litters of four pigs each were fed under standard conditions. The rate of gain and feed
efficiency were recorded as well as carcass data. “Advances made in the carcass traits (body length, belly and
backfat thickness) plus efficiency of feed utilization were phenomenal.” (M.E. Ensminger, December 1942).
