The main objective of this study was to evaluate the effect of methionine supplementation when reducing fishmeal levels in diets for white shrimp (Litopenaeus vannamei). Tested diets consisted of a positive control with 260 g/kg fishmeal (D1), two negative controls with 100 g/kg fishmeal and no amino acid (AA) supplementation (D2) or supplemented with lysine but not methionine (D3), and four additional...
Different ration levels were used to determine the digestible methionine (DMet) and lysine (DLys) maintenance requirements and the utilization efficiencies for gain above maintenance for two different sizes of tilapia (20.7 and 165 g), by feeding a soybean meal–based diet. Protein gain and amino acid (AA) gain (e.g. methionine, Met; lysine, Lys; R2 = 0.98) were best‐fit linear functions of DMet and...
