本试验旨在研究饲粮中添加不同水平木薯渣对22~49日龄仔鹅生长性能、屠宰性能及内脏器官发育的影响。选取300只19日龄健康、体重相近的扬州鹅公鹅，随机分为5组，每组6个重复，每个重复10只。对照组饲喂基础饲粮，试验组分别饲喂添加5%、10%、15%和20%木薯渣的试验饲粮，试验期28 d。结果表明：1)与对照组相比，饲粮中添加木薯渣显著提高22~28日龄、29~35日龄、22~49日龄仔鹅的平均日采食量和22~28日龄、22~49日龄仔鹅的平均日增重( P<0.05)，其中22~49日龄仔鹅的平均日增重与木薯渣添加水平呈二次曲线关系( P=0.017)，达到最高平均日增重的木薯渣添加水平是12.4%。2)与对照组相比，饲粮中添加木薯渣显著降低仔鹅的肌胃指数和十二指肠的相对重量( P<0.05)。3)对各组饲粮增重成本降低的百分比进行曲线模拟，结果呈现二次曲线关系( P<0.05)；当饲粮中木薯渣添加水平为17.9%时，增重成本降低百分比值最大。由此可见，饲粮中添加木薯渣可以促进22~49日龄仔鹅生长，降低饲料成本，对肌胃、十二指肠的发育有一定的影响。根据饲粮中添加木薯渣对平均日增重最高限量和饲料增重成本的最低限量，建议添加水平为12.4%~17.9%。
本試驗旨在研究飼糧中添加不同水平木藷渣對22~49日齡仔鵝生長性能、屠宰性能及內髒器官髮育的影響。選取300隻19日齡健康、體重相近的颺州鵝公鵝，隨機分為5組，每組6箇重複，每箇重複10隻。對照組飼餵基礎飼糧，試驗組分彆飼餵添加5%、10%、15%和20%木藷渣的試驗飼糧，試驗期28 d。結果錶明：1)與對照組相比，飼糧中添加木藷渣顯著提高22~28日齡、29~35日齡、22~49日齡仔鵝的平均日採食量和22~28日齡、22~49日齡仔鵝的平均日增重( P<0.05)，其中22~49日齡仔鵝的平均日增重與木藷渣添加水平呈二次麯線關繫( P=0.017)，達到最高平均日增重的木藷渣添加水平是12.4%。2)與對照組相比，飼糧中添加木藷渣顯著降低仔鵝的肌胃指數和十二指腸的相對重量( P<0.05)。3)對各組飼糧增重成本降低的百分比進行麯線模擬，結果呈現二次麯線關繫( P<0.05)；噹飼糧中木藷渣添加水平為17.9%時，增重成本降低百分比值最大。由此可見，飼糧中添加木藷渣可以促進22~49日齡仔鵝生長，降低飼料成本，對肌胃、十二指腸的髮育有一定的影響。根據飼糧中添加木藷渣對平均日增重最高限量和飼料增重成本的最低限量，建議添加水平為12.4%~17.9%。

This experiment was conducted to investigate the effects of dietary cassava residues supplemental level on growth performance, slaughter performance and visceral development of geese at 22 to 49 days of age. Three hundred 19-day-old healthy male geese with similar body weight were randomly allocated into 5 groups with 6 replicates in each group and 10 geese in each replicate. The control group was fed a basal diet, and ex-perimental groups were fed experimental diets supplied with 5%, 10%, 15% and 20% cassava residues, re-spectively. The experiment lasted for 28 days. The results showed as follows: 1 ) compared with the control group, dietary supplied with cassava residues significantly improved the average daily feed intake ( ADFI) at 22 to 28, 29 to 35 and 22 to 49 days of age and the average daily gain ( ADG) at 22 to 28, 22 to 49 days of age ( P<0.05) . The ADG of geese at 22 to 49 days had a quadratic curve relationship with the supplemental level of cassava residues ( P=0.017) . When the ADG achieved highest, the supplemental level of cassava resi-dues was 12.4%. 2) Compared with the control group, dietary supplied with cassava residues significantly re-duced muscular stomach index and the relative weight of duodenum (P<0.05). 3) The reduce percentage of fodder costs of each groups had a relationship of quadratic curve ( P<0.05) . When the amount of cassava resi-dues was 17.9%, the percentage was biggest. Therefore, the diets of adding appropriate cassava residues can stimulate the growth of geese and reduce the costs of fodder at 22 to 49 days of age. They also has a certain in-fluence on the development of muscular stomach and duodenum. According to the average daily gain maximum limits and feed cost minimum limit, the suggested amount of cassava residues added to dietary is 12. 4% to 17.9%.
