The experiment was conducted to investigate the effects of whole-plant corn silage on the intestinal length,organ indexes,and serum biochemical indexes of Taizhou geese.A total of 180 female Taizhou breeding geese at 35 days old were randomly divided into six groups with three replicates in each group and 10 geese in each replicate.The control group was fed a basic diet,while Group Ⅰ～Group Ⅴ were fed the whole-plant corn silage that replaced 10％,20％,30％,40％,and 50％of the basic diet.The pre-test period was 7 days and the experimental period was 49 days.The results indicate that at 71 days of age,the lengths of the cecum in Group Ⅱ and Group Ⅳ,the cecum in Group Ⅴ,and the rectum in Group Ⅳ were significantly higher than those in the control group(P＜0.05).At 92 days of age,the length of the rectum in Group Ⅳ was significantly higher than that in the control group(P＜0.05).At 71 days of age,the liver index in Group V was superior to the control group and Group Ⅰ and Group Ⅳ(P＜0.05),and the gizzard index was higher than that in the control group(P＜0.05).At 92 days of age,the TP concentration in Group Ⅱ,Group Ⅲ,Group Ⅳ,and Group Ⅴwas higher than that in the control group.The AST activity in the control group was higher than that in Group Ⅱ and Group Ⅴ(P＜0.05).The study indicates that replacing the basic diet with whole-plant com silage has no negative effect on the development of the hearts and livers of Taizhou geese aged 43～92 days.It can promote the development of the digestive organs,protein anabolism,and deposition,with the suitable substitution ratio being 20％to 30％.
