Prior to the series of experiment to determine the individual amino acid requirement, effects of dietary crude protein (CP) level for maximum performance, plasma concentrations of amino acids and biochemical components of female growing pigs were investigated. Twenty female growing pigs weighing about 25.2kg were allotted to 5 groups of 4 pigs and group-fed experimental diets ad libitum for 21 days. The experimental diets were mainly consisted of corn, soybean meal and wheat bran, and formulated to meet 80, 90, 100, 110 and 120% of the requirements by Japanese Feeding Standard for Swine (JFSS, 1987) for lysine, sulfur amino acids and threonine
