Abstract: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.
