Diet of the experimental group of the content of grape seed cake were 0.00,3.00%, 6.00%, 9.00%, 12.00%, 15.00%. Fecal-wide collection to determine crude protein (CP), amino acid (AA) digestibility and manure ammonia nitrogen (NH3-N) concentration in order to preliminary explore the different dietary grape seed cake to add the proportion of nitrogen metabolism in geese.The results showed that: in the ME and CP intake, such as the same conditions, the goose Dietary grape seed cake,Its N deposition and NPU were significantly (P0.05) or very significantly (P 0.01) higher than the control group, the group adding 6% was the highest, which reached 1.44g and 47.64% respectivly.its; each group fecal ammonia nitrogen (NH3-N) concentrations were significantly (P0.05) or very significantly (P0.01) lower than the control group, its adding the minimum at 9.00%, reaching 80.49 mg / kg; in addition to glutamic acid ( Glu), the grape seed cake when its adding 9.00% of the amino acid apparent digestibility (AAAD) is relatively high (81.92% ~ 94.25%), significa
