A trial was conducted to investigate energy and nutrient digestibility of cassava leaf meal (CLM), casein (CAS), fish meal (FM), full-fat soya bean (FFSB) and extracted soya bean meal (SBM). The basal diet containing cassava root meal (CRM) and FFSB meal and the other five dietary treatments were evaluated with 12 crossbred castrated male pigs in a metabolism study covering three successive experimental periods between 40 and 60 kg body weight (BW). Total tract digestibility of dry matter (DM), organic matter (OM) and gross energy (GE) of diets, generally increased significantly (p < 0.05) from CLM diet to FFSB and FM diets and finally to CAS and SBM diets, corresponding to a decrease in fibre content in the diets. Except for CAS diets, the pattern of acid detergent fibre (ADF) digestibility followed a similar trend. Significantly higher ADF digestibility was recorded for soya bean diets while ADF digestibility value obtained for CLM diet was significantly lower. The digestible energy values obtained for CAS, FM, FFSB, SBM and CLM were 22.2, 16.3, 17.5, 17.0 and 8.0 MJ/kg DM, respectively. Corresponding metabolizable energy values were 22.1, 15.6, 17.1, 16.3 and 7.6 MJ/kg DM, respectively,
进行了一项试验，以研究木薯叶粉（CLM）、酪蛋白（CAS）、鱼粉（FM）、全脂大豆（FFSB）和大豆粕（SBM）的能量和养分消化率。在一项代谢研究中，用12头杂种去势公猪对含有木薯根粉（CRM）和FFSB粉的基础日粮以及其他五种日粮处理进行了评估，该研究涵盖了体重在40至60千克之间的三个连续实验期。日粮的干物质（DM）、有机物质（OM）和总能（GE）的全肠道消化率，通常从CLM日粮到FFSB和FM日粮，最后到CAS和SBM日粮显著增加（p<0.05），这与日粮中纤维含量的降低相对应。除了CAS日粮外，酸性洗涤纤维（ADF）消化率的模式遵循类似趋势。大豆日粮的ADF消化率显著更高，而CLM日粮的ADF消化率值显著更低。CAS、FM、FFSB、SBM和CLM的可消化能量值分别为22.2、16.3、17.5、17.0和8.0兆焦/千克干物质。相应的代谢能值分别为22.1、15.6、17.1、16.3和7.6兆焦/千克干物质。
