%X Existence metabolism of the common teal (Anas crecca) , shoveller (Anas cl-ypeata) and spotbill duck (Anas poecilorhycha) kept in cage was determined during the wintering season. The results showed that amount of food intake was 32.4g ind-1·day-1 in the common teal, 54.9 g ind-1·day-1 in the shoveller and 80.2 g ind-1·day-1 in the spotbill duck . The average efficiency of digestion was 75.6% in the common teal, 73.7% in the shoveller and 73.8% in the spotbill duck. The metabolizable energy was 102.7 kcal in...
