摘要

摘要本试验研究了玉米酒糟干粒和可溶性物(DDGS)、去皮羽扇豆粕(DHLM)和去脂豆粕(DSBM)对橙斑石斑鱼的表观消化系数(adc)。DHLM的ADCcp最高(97%)，DDGS的ADCcp为90%，与DSBM的ADCcp相近(89%)。DHLM的可消化蛋白(DP)为523 g kg - 1，显著高于DSBM (495 g kg - 1)， DDGS的DP最低(457 g kg - 1)。DSBM与DHLM的消化能(DE)无显著差异(17.53 MJ kg−1)，DDGS的消化能(DE)最低(15.77 MJ kg−1)。纤维种类与adc之间的关系表明，降低DHLM和DDGS中的纤维种类有助于提高橙斑石斑鱼的消化率。

Digestibility of dehulled lupine meal, corn distiller’s dried grain with solubles and de-fatted soybean meal for orange-spotted grouper Epinephelus coioides

ABSTRACT Our study investigated the apparent digestibility coefficients (ADCs) of corn distiller’s dried grains with solubles (DDGS), dehulled lupine meal (DHLM) and de-fatted soybean meal (DSBM) for orange-spotted grouper Epinephelus coioides. The ADCcp of DHLM (97%) was the highest while the ADCcp of DDGS (90%) was similar to that of DSBM (89%). Digestible protein (DP) of DHLM (523 g kg−1) was significantly higher than that of DSBM (495 g kg−1) while DP of DDGS (457 g kg−1) was the lowest. We found no difference in digestible energy (DE) between DSBM (17.53 MJ kg−1) and DHLM (16.99 MJ kg−1) while DE of DDGS (15.77 MJ kg−1) was also the lowest. The relationship between fiber class and ADCs suggested that reducing fiber class in DHLM and DDGS should be helpful for the orange-spotted grouper’s digestibility.
