养殖鱼类对干啤酒糟和发酵啤酒糟饲料的表观消化率
Apparent digestibility coefficients of dried or fermented brewer’ s grains for cultured fish
摘要
Abstract
Objective] To determine the apparent digestibility of dry matter, crude protein, crude lipid and crude fiber of dried or fermented brewer’ s grains in grass carp ( Ctenopharyngodon idellus) , tilapia ( Oreochromis niloticus) , yellow catfish ( Peltobagrus fulvidraco) and Scortum barcoo. [Method] The ex-perimental diets were consisted of 70% basal diet and 30% test feed ingredients, and Cr2 O3 was added as an exogenous indicator. The fecal samples were collected by siphon after four weeks of feeding. [Re-sult]The apparent digestibility coefficients of dried and fermented brewer ’ s grains in different fish were significantly different ( P<0. 001 ) . The apparent digestibility coefficients of dried and fermented brew-er’ s grains in grass carp and tilapia were significantly higher compared with those in yellow catfish and Scortum barcoo (P<0. 05). After fermentation, the apparent digestibility coefficients of fermented brew-er’s grain significantly increased compared to those of dried brewer’s grain in four fish species(P <0. 05). [Conclusion] Herbivorous and omnivorous fish can utilize the dried brewer’s grain better com-pared with carnivorous fish. The utilization of dried brewer’ s grain in fish can be improved by fermenta-tion. Fermented brewer’ s grain can be used in considerable amounts for herbivorous and omnivorous fish, but only in limited amounts for carnivorous fish.关键词
