Dietary folic acid coordinates growth and lipid metabolism through gut microbial and one-carbon networks in juvenile mud crab (Scylla paramamosain).

Abstract

< 0.05), while reducing oxidative stress-tolerant, anaerobic, and potentially pathogenic bacteria in the intestine. These findings indicate that juvenile mud crab have a limited capacity for FA synthesis and require dietary supplementation. A dietary FA level of 4.26 mg/kg supported optimal growth and physiological functions, while two-slope broken-line regression of PWG against dietary FA levels estimated an optimal dietary requirement of 3.86 mg/kg for juvenile mud crab.
