Methionine-Mediated Regulation of Intestinal Structure and Lipid Transport in the Rice Field Eel (Monopterus albus)

An eight-week feeding trial discusses how methionine affects intestinal barrier and lipid transport on rice field eel (Monopterus albus). Six isoenergetic and isonitrogenous feeds contained different levels of methionine (0, 2 g/kg, 4 g/kg, 6 g/kg, 8 g/kg, or 10 g/kg). Compared with M0 (0 g/kg), gastric amylase, lipase, and trypsin were remarkably increased as dietary methionine (P
