After WWII, slackened government demand crashed the poultry market. Producers switched chickens from fishmeal to soybeans to cut costs, but chickens did poorly even with vitamins added.

In 1948, Thomas Jukes found the needed boost. In his experiment birds that had gotten the highest dose of a cheap Aureomycin-containing byproduct weighed 2.5X the control chick's weight, 1/3 more than those receiving B12, and 1/4 more than those receiving liver extract, something no farmer could afford.
