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 study was to analyze the effects of herbal plant supplementation on rumen fermentation, total gas, and methane production, dry matter digestibility (IVDMD), organic matter digestibility (IVOMD), and protozoa populations within the rumen.
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).
Experiment 1 revealed that (EL), (CLA), and (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 NH 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.
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.
在畜牧业，尤其是反刍动物中，可通过一种饲养策略来尽量减少甲烷排放，该策略涉及使用含有生物活性化合物的草药植物，这些化合物可减少原生动物并降低甲烷气体排放。本研究的目的是分析添加草药植物对瘤胃发酵、总气体和甲烷产量、干物质消化率（IVDMD）、有机物消化率（IVOMD）以及瘤胃内原生动物种群的影响。
本研究进行了两项实验。实验1旨在确定最有潜力增加总气体产量并减少原生动物种群的草药植物。在实验2中继续使用实验1中挑选出的三种潜在草药作为基于棕榈仁粕（PKM）的日粮（70% PKM + 30%草药植物）中的补充剂。
实验1表明，（EL）、（CLA）和（CSA）是增加总气体产量以及IVDMD和IVOMD百分比的潜在草药候选物。在实验2中，添加EL、CLA和CSA显著提高了IVDMD，从62.84%提高到70.15%，IVOMD从61.61%提高到53.18%，NH从13 mM提高到17 mM，同时减少了部分挥发性脂肪酸和总气体产量。此外，甲烷气体和原生动物种群也减少了。
与对照组相比，使用EL、CLA和CSA可有效提高总气体产量、IVDMD和IVOMD，同时减少瘤胃发酵中的甲烷气体原生动物种群。
