This study evaluated if reduced water exchange in an intensive, outdoor culture system could spare dietary Met (Met+Cys) required for maximum growth performance of juvenile Pacific white shrimp.
This study tested five diets formulated with increasing levels of methionine (Met) and Met + cysteine (Cys) and their effect on growth performance of juvenile Pacific white shrimp stocked at 50, 75 or 100 animals/m2 in a green water system.
In a study, the authors evaluated the performance of juvenile white shrimp grown at high density and fed diets with varying levels of methionine. Trends toward improvements in feed intake were observed for diets with reduced fishmeal and HMTBa supplementation.
A study compared the effects of two forms of methionine supplemented at different levels in feeds for Pacific white shrimp. Test diets containing methionine bound in soy protein had less leaching of methionine than the diets containing crystalline methionine.
Research on the methionine requirement for white shrimp showed a diet requirement of 0.45 percent using a protein-bound form of methionine.
