摘要
采用体外消化法,测定了真蛸(Octopus vulgaris)和虎斑乌贼(Sepia pharaonis)对8种饲料原料的表观消化率.结果表明,这两种动物对动物性饲料原料的体外消化率较高,干物质65.28~85.65%,粗蛋白64.99%~90.10%;对植物性饲料原料的消化率其次,其中干物质40.07%~60.02%,粗蛋白为57.75%~67.56%;对DDGS的体外消化率最低,干物质为25.24%~26.25%,粗蛋白为34.74%~52.90%.另外,真蛸对大部分饲料原料的体外消化率均高于虎斑乌贼.研究结果可为真蛸和虎斑乌贼饲料原料的选择提供参考依据.
Apparent digestibilities of 8 feedstuffs for Octopus vulgaris and Sepia pharaonis were determined in vitro. The results showed, the apparent digestibilities of animal feedstuffs were relatively higher, dray matter 65.28%~85.65%,crude protein 64.99%~90.10%, then followed by those of plant feedstuffs, dry matter 40.07%~60.02%,crude protein 57.75%~67.56%, while that of DDGS was the lowest, dry matter 25.24%~26.25%,crude protein 34.74~52.90%. The digestibilities of most feedstuffs for Octopus vulgaris were higher than those for Sepia pharaonis to different degrees. The results may provide references in feedstuff choosing for Octopus vulgaris and Sepia pharaonis.
