A.S. Series 69-40
In 1935 workers at the Connecticut Agricultural Experiment Station discovered a mutant gene in corn called Opaque-2. Yet high-lysine corn, the product of this discovery, was not identified until 1963 at Purdue University. Since that time several experiments have been conducted on the value of the product in both human and animal nutrition. Also, considerable research is under way on the production aspects of high-lysine corn. Regular corn is deficient in two of the essential amino acids needed by swine--lysine and tryptophan. High-lysine corn is also higher in tryptophan than normal corn. In certain other amino acids high-lysine corn may be higher or lower than normal corn. This experiment was conducted to study the value of high-lysine corn in rations for young growing pigs when the protein requirements are more critical than later in the growing period.
