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 ( groupⅠ, groupⅡ, 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%, re-spectively. 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.
