Abstract

Objective: This study aims to investigate the nutritional composition and rumen fermentation attributes of the tithonia plant (Tithonia diversifolia) treated with Lactobacillus bulgaricus bacteria at different fermentation durations and doses.

Materials and methods: In this research, an experimental approach employed a factorial pattern with two factors as treatments with three replications using a complete randomized design. The primary factor was the dose of L. bulgaricus inoculum, with concentrations at 2% and 3%. The secondary factor examined during the study revolved around the duration of fermentation, offering three time frames of 1 day, 3 days, and 5 days for analysis. The inoculum of L. bulgaricus contained 65 × 1015 CFU/ml.

Results: The use of L. bulgaricus bacteria on tithonia plants (T. diversifolia) with different inoculum doses and fermentation times demonstrated a highly significant effect and significant disparities (p < 0.05). In phytic acid content, nutrient content (crude protein (CP), crude fiber, crude fat, and dry matter (DM)), and in vitro digestibility, which includes DM, organic matter (OM), CP, volatile fatty acids (VFA), NH3, and gas production. However, it did not show any significant interaction between pH and OM content.

Conclusion: The optimal results of nutrient profiling and in vitro digestibility, including DM, OM, CP, rumen pH, VFA, NH3 (ammonia), and gas production, were observed when the tithonia plant (T. diversifolia) was fermented using L. bulgaricus with 3% inoculum doses and a fermentation time of 5 days.

不同时间和剂量下用保加利亚乳杆菌发酵的椴树营养成分和瘤胃发酵。
研究目的本研究旨在探讨用保加利亚乳杆菌(Lactobacillus bulgaricus)处理不同发酵时间和剂量的缇香植物(Tithonia diversifolia)的营养成分和瘤胃发酵属性:本研究采用完全随机设计,以两个因子作为处理,三个重复的因子模式进行实验。主要因素是保加利亚乳杆菌接种物的剂量,浓度为 2% 和 3%。研究中考察的次要因素是发酵持续时间,提供了 1 天、3 天和 5 天三个时间段进行分析。保加利亚乳杆菌的接种物含有 65 × 1015 CFU/ml:结果:在不同接种量和发酵时间下,保加利亚乳杆菌对蓟马(T. diversifolia)的影响非常明显,且差异显著(p < 0.05)。在植酸含量、养分含量(粗蛋白(CP)、粗纤维、粗脂肪和干物质(DM))和体外消化率(包括 DM、有机物(OM)、CP、挥发性脂肪酸(VFA)、NH3 和产气量)方面均有显著差异。但是,pH 值与 OM 含量之间没有明显的交互作用:当使用保加利亚酵母菌(L. bulgaricus)以 3% 的接种量和 5 天的发酵时间发酵噻吨草(T. diversifolia)时,营养分析和体外消化率(包括 DM、OM、CP、瘤胃 pH 值、挥发性脂肪酸、NH3(氨)和产气量)都能达到最佳结果。
