In this study, we evaluated the effect of steam explosion of oil palm frond (OPF) and oil palm empty fruit bunch (EFB) on nutrient composition and ruminal fermentation characteristics in vitro. The results showed that steam explosion decreased NDF (P < 0.01), ADF (P < 0.01), and hemicellulose content (P < 0.01) in OPF and EFB. Steam explosion improved the effective energy value of OPF and EFB. In vitro fermentation results revealed that 72-h gas production capacity of OPF and EFB increased by 12.60and 85.06% (P < 0.01), respectively, after steam explosion. Steam explosion had a tendency to improve the concentration of total volatile fatty acids (TVFA) (P = 0.082). In conclusion, steam explosion of OPF and EFB reduced NDF, ADF, and hemicellulose content and increased gas production and TVFA concentration.
在本研究中，我们评估了油棕叶（OPF）和油棕空果串（EFB）的蒸汽爆破对体外营养成分和瘤胃发酵特性的影响。结果表明，蒸汽爆破降低了OPF和EFB中的中性洗涤纤维（NDF）（P<0.01）、酸性洗涤纤维（ADF）（P<0.01）和半纤维素含量（P<0.01）。蒸汽爆破提高了OPF和EFB的有效能值。体外发酵结果显示，蒸汽爆破后，OPF和EFB的72小时产气量分别增加了12.60%和85.06%（P<0.01）。蒸汽爆破有提高总挥发性脂肪酸（TVFA）浓度的趋势（P=0.082）。总之，OPF和EFB的蒸汽爆破降低了NDF、ADF和半纤维素含量，增加了产气量和TVFA浓度。
