Western Illinois University in Macomb, Illinois, conducts an annual performance testing program for rams and bucks.
This year, a Suffolk ram lamb consigned by J & L Suffolks from Farmersburg, Iowa, had a rib eye area that measured 6.12 square inches. The measurement was taken three times, with less than 1% error.
The ram's average daily gain was 1.21 lbs. His feed efficiency was 3.84, meaning he consumed 3.84 lbs. of feed to gain one lb. of live weight. He was the highest indexing Suffolk in the test.
