Effects of saline drinking water on growth performance, carcass traits, and blood biochemistry in crossbred Muscovy ducks

Male crossbred Muscovy ducks can tolerate drinking water salinity levels up to 0.3%, whereas females can withstand salinity up to 0.6%. The greater salinity tolerance of female ducks makes them more suitable for farming in saline-affected areas. While increased salt gland size suggests an adaptive response, elevated blood biochemical markers indicate potential physiological stress. Future research should explore strategies to mitigate the negative effects of saline water on duck production, including dietary interventions with antioxidants such as vitamin E or selenium.
