■在畜牧业,尤其是反刍动物,一种尽量减少甲烷排放的方法可以通过一种饲养策略来进行,该策略涉及含有生物活性化合物的草药植物,这些化合物可以减少原生动物和甲烷气体的排放。这项体外研究的目的是分析草药植物补充对瘤胃发酵的影响。总气体,和甲烷生产,体外干物质消化率(IVDMD),体外有机质消化率(IVOMD),瘤胃内的原生动物种群。
■在本研究中进行了两个实验。进行实验1以确定能够增加总气体产量和减少原生动物种群的最有前途的草药植物。在实验2中继续在实验1中选择的三种潜在草药作为基于棕榈仁粉(PKM)的日粮(70%PKM30%草药植物)中的补充剂。
■实验1显示长叶Eurycoma(EL),可乐(CLA),和决明子(CSA)是潜在的草药候选物,可提高总气体产量以及IVDMD和IVOMD的百分比。在实验2中,补充EL,CLA,CSA将IVDMD从62.84%显著增加到70.15%,IVOMD从61.61%提高到53.18%,和NH3从13mM到17mM,以及减少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数量减少。
■EL的利用,CLA,CSA有效地增加了总天然气的产量,IVDMD,与对照相比,瘤胃发酵中甲烷气原生动物种群减少和IVOMD。
UNASSIGNED: 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.
UNASSIGNED: 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).
UNASSIGNED: 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.
UNASSIGNED: 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.
