“…Increased digestibility in ruminant livestock shows that nutrients that can be broken down by microbes in the rumen are also increasing [ 19 ]. The increase in OM followed the increase in DM [ 19 , 20 ]. The findings of this study align with Phesatcha et al research [ 21 ], which suggested that feed ingredients with lower fiber content are more easily digestible due to their thin cell walls, making them more susceptible to breakdown by active microorganisms in the rumen.…”

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.

Background and Aim: In the livestock sector, particularly ruminants, an approach to minimize methane emissions can be carried out through a feeding strategy involving herbal plants containing bioactive compounds that can reduce protozoa and decrease methane gas emissions. The aim of this in vitro study was to analyze the effects of herbal plant supplementation on rumen fermentation, total gas, and methane production, in vitro dry matter digestibility (IVDMD), in vitro organic matter digestibility (IVOMD), and protozoa populations within the rumen. Materials and Methods: Two experiments were conducted in this study. Experiment 1 was conducted to determine the most promising herbal plants capable of increasing total gas production and reducing protozoan populations. Three potential herbals selected in Experiment 1 were continued in Experiment 2 as supplements in the palm kernel meal (PKM)-based ration (70% PKM + 30% herbal plants). Results: Experiment 1 revealed that Eurycoma longifolia (EL), Cola acuminata (CLA), and Cassia alata (CSA) were potential herbal candidates for enhancing total gas production and the percentages of IVDMD and IVOMD. In Experiment 2, supplementation with EL, CLA, and CSA significantly increased IVDMD from 62.84% to 70.15%, IVOMD from 61.61% to 53.18%, and NH3 from 13 mM to 17 mM, as well as reduced partial volatile fatty acids and total gas production. In addition, the methane gas and protozoan populations were reduced. Conclusion: The utilization of EL, CLA, and CSA effectively increased the production of total gas, IVDMD, and IVOMD while reducing methane gas protozoa populations in rumen fermentation compared with the control. Keywords: feed digestibility, methane emissions, plant herbs, protozoa.

BACKGROUNDThe demand for animal products is increasing in developing countries due to population growth. However, livestock production contributes significantly to global warming, accounting for 25%. Probiotics can help improve livestock efficiency by enhancing gut microbes and fat metabolism. They can modify rumen populations, enhance fermentation, reduce methane emissions and improve feed digestion. In this study, the goal was to determine the most effective method of reducing methane emissions in the rumen of sheep in vitro by adding different concentrations of Saccharomyces cerevisiae and Bacillus subtilis.RESULTSAdding 8 × 106 CFU g−1 S. cerevisiae during fermentation reduced pH levels after 48 h. This also increased the concentrations of NH3‐N, microbial protein and total gas production. At the same time, it decreased methane emissions. Furthermore, adding 20 × 106 CFU g−1 B. subtilis to the mixture increased total gas production (TGP) and methane production, with the highest production observed after 48 h. However, it did not affect pH levels after 48 h.CONCLUSIONIt can be concluded that S. cerevisiae had significantly increased microbial protein and NH3‐N concentrations after fermentation without altering pH. Additionally, the addition of S. cerevisiae enhanced TGP and reduced methane emissions. It is worth noting that TGP increased because B. subtilis was added at a concentration of 20 × 106 CFU g−1, with no significant differences between concentrations. Therefore, we recommend adding S. cerevisiae and B. subtilis to the diet at doses of 8 and 20 × 106 CFU g−1, as it resulted in higher TGP and reduced methane emissions. © 2024 Society of Chemical Industry.
