摘　　要：我国花生种植面积世界第一,但花生藤却没有得到充分利用。因此本试验通过研究四川白鹅对花生藤营养物质的表观消化率,确定其在四川白鹅日粮中的合理添加量,为优化日粮配方和花生藤的合理利用提供理论依据和数据参考。试验随机选取18周龄、(3.5±0.25)kg四川白鹅公鹅12只,采用强饲法(全收粪法),每只试验鹅用强饲器强饲40 g风干的花生藤粉,并对应收集24 h的全部排泄物质,分别测定花生藤和排泄物中的营养成分,计算各养分的表观消化率。结果表明:除粗蛋白质的消化率仅为17.7%外,四川白鹅对花生藤其他营养成分消化率均较高,尤其是对粗脂肪和钙的消化率,分别可达58.33%和70.98%。表明花生藤可作为鹅的粗饲料补充料。China has the largest planting area of peanut vine in the world,however,peanut vine are not fully utilized.This study was conducted to study the apparent digestibility of nutrients in peanut vine in Sichuan white geese.Twelve Sichuan white geese(male),aged 18 weeks and(3.5±0.25)kg were randomly selected,and each goose was force-feed by 40 g peanut vine(dry matter).All excretion(24 h)were collected.The results showed that crude protein digestibility was only 17.7%,however,the digestibility of crude fat and calcium was 58.33%and 70.98%,respectively.Therefore,peanut vine could be used as roughage supplement for geese.
