| 摘 要： | 采用"胃-肠"两步法测定了加州鲈(Micropterus salmoides)对15种饲料原料的体外消化率,并与银鲈(Bidyanus bidyanus)体内消化率数据进行了比较。结果表明:加州鲈对秘鲁鱼粉、喷干血粉、豆粕、花生麸、玉米蛋白粉、酵母膏、破壁酵母7种原料的体外消化率较高(干物质>45%,蛋白质>71%),对玉米、DDGS消化率较低(干物质<17%,蛋白质<61%),且大部分原料的体内、外消化率结果具有极显著的相关性(P<0.01)。体外消化率的结果可为加州鲈饲料原料的选择提供参考依据。

| Abstract: | Apparent digestibilities of 15 feedstuffs in vitro for largemouth bass(Micropterus salmoides) were determined by stomach-intestine two-step method and the results were compared with apparent digestibilities in vivo for silver perch(Bidyanus bidyanus).The results showed that,the apparent digestibilities of peruvian fishmeal,spray-dried blood meal,soybean meal,peanut residue,corn gluten meal,yeast extract and wall-broken yeast extract in vitro were higher(dry matter digestibilities >45% and crude protein digestibilities >71%),while that of corn and DDGS was relatively lower(dry matter digestibilities <17% and crude protein digestibilities <61%),and significant correlations were found between apparent digestibilities for most of the detected feedstuffs in vitro and in vivo(P<0.01).The results of digestibility in vitro can be regarded as a reference in feedstuff choosing for largemouth bass. |
