This experiment was conducted to evaluate the nutritional values of cassava residue and determine metabolizable energy (ME) and major nutrient utilization of cassava residue for geese. Eighteen 60-week-old healthy male Yangzhou geese with similar body weight were randomly divided into 3 groups (group Ⅰ, group Ⅱ, group Ⅲ) with 6 replicates per group and 1 goose per replicate. The method of forced-feeding was used in this metabolism experiment. 100 g basal diet was forced fed in group Ⅰ, and 100 g diet which by substituting 20%, 40% of the basal diet with cassava residue were forced fed in group Ⅱ and group Ⅲ, respectively. Method of quadric equations was used to obtain the utilization of nutrient of cassava residue. The results showed as follows:1) gross energy (GE) and the contents of crude protein (CP), ether extract (EE), crude fiber (CF), neutral detergent fiber (NDF), acid detergent fiber (ADF), total phosphorus (TP), calcium (Ca) of cassava residue were 15.49 MJ/kg, 10.47%, 1.73%, 19.13%, 56.12%, 45.15%, 0.17% and 0.50%, respectively. Contents of amino acid (AA) of cassava residue were very rich, and the content of glutamic (Glu) was up to 0.99%. 2) The apparent metabolizable energy (AME) and true metabolizable energy (TME) of cassava residue were 3.73 and 5.08 MJ/kg, respectively. The utilization of CP, CF, ADF, NDF, TP and Ca of cassava residue were 30.01%,56.31%,77.62%,65.16%,12.58% and 14.77%, respectively. Utilization of AA of cassava residue were relatively low, the utilization of arginine (Arg), proline (Pro), Glu, cysteine (Cys), threonine (Thr) and aspartate (Asp) were 72.15%, 60.80%, 58.40%, 52.41%, 50.04% and 8.88%, respectively. It is concluded that fiber contents cassava residue are higher, AA contents are rich, it can be fed by geese, and fiber in cassava residue can be better used by geese.
