摘要
本研究的重点是探讨楝树叶提取物(NE)对苯乙烯类青贮饲料发酵过程和细菌群落的影响。在青贮过程中的不同时间点(第 3、7、14 和 30 天),分别用 0%、1% 和 2% 的 NE 青贮新鲜原料,并分析各种发酵参数、氮成分和微生物组成。实验结果表明,与对照组相比,在腌制过程中添加 NE 可改善发酵参数,包括提高乳酸和醋酸水平,降低 pH 值、大肠菌群数量和氨氮浓度。此外,添加 NE 后,乳酸菌和木薯球菌的相对丰度增加,而肠杆菌的生长受到抑制。这些结果表明,作为一种新型青贮饲料添加剂,NE 有助于减少有害细菌的数量,提高苯乙烯青贮饲料的营养质量和发酵特性。
Effects of Neolamarckia cadamba Leaf Extract on Dynamic Fermentation Characteristics and Bacterial Community of Stylosanthes guianensis Silage
This study focused on exploring the effects of Neolamarckia cadamba leaf extract (NE) on the fermentation process and bacterial community of stylo (Stylosanthes guianensis) silage. Fresh raw materials of stylo were ensiled with 0%, 1%, and 2% NE, and various fermentation parameters, nitrogen components, and microbial compositions were analyzed at different time points (days 3, 7, 14, and 30) during the ensiling process. The experiment showed that, in comparison to the control group, incorporating NE into the ensiling process resulted in improved fermentation parameters, including increased lactic acid and acetic acid levels, as well as decreased pH, coliform population, and ammonia nitrogen concentration. Moreover, the relative abundances of Lactobacillus and Pediococcus were augmented, while the growth of Enterobacter was inhibited by the NE addition. These results suggest that NE has potential as a novel additive for silage, promoting a reduction in harmful bacteria and enhancements in the nutritional quality and fermentation characteristics of stylo silage.
