“…The latter study utilized an extract from Cnidoscolus aconitifolius , which was included in the ration in pelleted form and contained 2.3% of total tannins and 7.3% of total flavonoids; authors concluded that the use of these inclusion levels represents a promising approach to enhance rumen fermentation and to mitigate CH 4 production. However, in the present study, AZI contained twofold the number of flavonoids (expressed as quercetin) that Totakul and coworkers used ( 26 ). This indicates that the increase in gas production can be attributed to the quercetin’s stimulatory effect on the ruminal microbes, resulting in increased activity ( 2 ).…”

“…Thus, leaf extracts used in the present experiment might have an effect on the cumulative gas production after 48 h of in vitro incubation. Previously, the increase in gas volumes observed in extracts rich in condensed tannins, phenolics, and flavonoids could be attributed to improved rumen fermentation and nutrient digestibility ( 26 ). The latter study utilized an extract from Cnidoscolus aconitifolius , which was included in the ration in pelleted form and contained 2.3% of total tannins and 7.3% of total flavonoids; authors concluded that the use of these inclusion levels represents a promising approach to enhance rumen fermentation and to mitigate CH 4 production.…”

“…The ruminal pH ranged between 6.50 and 6.97, which is normal for rumen ecology and the efficiency of rumen fermentation ( 26 , 47 ). A greater production of short chain fatty acids (SCFAs) is most likely explained by rumen digestibility when the rumen fluids were incubated with Mix.…”

“…It is worth noting, however, that studies conducted in vitro ( 23 – 25 ) should be confirmed by in vivo methods. Despite the promising effects of AZI and CNA for the mitigation of CH 4 emission, to the authors’ knowledge, there is limited research evaluating their effects in the rumen ( 26 ), which represents a research gap that needs to be addressed in the scientific literature. In this regard, the combination of two or more plant extracts might provide unique biological characteristics that differ from the individual extracts because of the potential synergistic effect ( 27 , 28 ).…”

IntroductionMitigation of ruminant greenhouse gas (GHG) emissions is crucial for more appropriate livestock production. Thus, there is a need of further research evaluating feed supplementation strategies to mitigate enteric GHG emissions and other gases produced within the rumen.MethodsThis study was conducted as a completely randomized experimental design to determine the effectiveness of liquid extracts from A. indica (AZI), C. angustidens (CNA), or their combination (Mix. 1:1) at dosages of 0, 36, 72, and 108 mg of liquid extract/g DM substrate incubated in reducing GHG production in vitro, particularly methane (CH4), from the diet of steers during anaerobic incubation in rumen fluid. Total gas production, CH4, CO, H2S, and fermentative characteristics were all measured in vitro.ResultsTreatment AZI at a dose of 108 mg of liquid extract/g DM substrate produced the highest (P < 0.05) gas volume at 6 h, whereas CNA at a dose of 72 mg of liquid extract/ g DM substrate produced the least (P < 0.05) at 6 and 24 h, and Mix. at a dose of 72 mg of liquid extract/g DM substrate produced the least (P < 0.05) at 48 h. In addition, CH4 levels at 6 and 24 h of incubation (36 mg/g DM substrate) were highest (P < 0.05) for CNA, and lowest (P < 0.05) for AZI, whereas this variable was lowest (P < 0.05) at 72 mg of liquid extract for CNA at 24 and 48 h. At 6 and 24 h, CO volume was highest (P < 0.05) for AZI at 108 mg of liquid extract and lowest (P < 0.05) for Mix. at 72 mg of liquid extract. Treatment Mix. had a high (P < 0.05) concentration of short chain fatty acids at 72 mg of liquid extract/g DM of substrate.DiscussionIn general, herbaceous perennial plants, such as AZI and CNA, could be considered suitable for mitigating enteric GHG emissions from animals. Specifically, the treatment Mix. achieved a greater sustainable reduction of 67.6% in CH4 and 47.5% in H2S production when compared to either AZI. This reduction in CH4 might suggest the potential of the combination of both plant extracts for mitigating the production of GHG from ruminants.
