Metabolizable energy (ME) is one of the major factors in formulating diets for ducks and most studies on the ME values of ingredients have been conducted on Peking ducks, with limited research on Muscovy ducks. Compared with the time-consuming in vivo digestion method, in vitro simulating digestion as a rapid and reliable method has been performed to predict ME and metabolizability of gross energy. Therefore, the precision of the in vitro digestion method was evaluated for Muscovy duck feed in our study.
