From: FMO3 deficiency of duck leads to decreased lipid deposition and increased antibacterial activity
The content and activity of FMO3 protease in the liver of ducks were at lower levels compared with that of chickens. A Immunohistochemical (IHC) staining for FMO3 expression in chicken and duck livers, the black box represents the stained FMO3 proteins indicated by the arrows with magnification. B FMO3 protease activity in duck and chicken livers (Wilcoxon rank-sum test), *P < 0.05. The CAU-3 (TT) chickens have impaired FMO3 function
