A.S. Series 64-23
The term "protein requirement" does not suffice any longer for the determination of a well balanced ration, and the term "amino acid requirement" is becoming more standard. Grain and protein feeds vary in their amino acid content and also vary in the availability of the amino acids. When a ration is formulated, the feedstuff amino acid content, amino acid availability and the amino acid requirement of the animal must be considered. These areas, plus amino acid interactions and others, include a broad field and all need extensive clarification. Research has been conducted at several experiment stations to evaluate different protein supplements and crystalline amino acids and their effect on the growth of swine. More amino acid research has been focused on baby and growing pigs, where as very little research has been conducted with finishing pigs.
