“…About 66% of the medicinal plants studied in Rivers State also had DMD of greater than 50%. The DMD values in this study are in agreement with the range values reported for the medicinal plants in the work of Bodas et al (2008) and Medjekal et al (2017). In Edo State, the medicinal plants influenced methane production in different ways with significant variations.…”

“…(represented by the SCFA value) along with the methane reduction by the medicinal plants is an advantage and this is consistent with earlier reports (Garcia-Gonzalez et al, 2008;Medjekal et al, 2017). The implication of this is that the medicinal plants have stimulated rumen microbial metabolism rather than been antagonistic or lethal to them, unlike what is frequently experienced with monensin.…”

“…Monensin's mode of action involves inhibition of some specific microorganisms (Scharen et al, 2017) leading to reduction in ruminal fermentation and digestibility. Ruminal production of VFA contributes about 70% of the energy needs of the ruminant animals (Medjekal et al, 2017). Specifically, the antimicrobial and/or the antimethanogenic properties of some of the medicinal plants and spices have been reported in literature.…”

Methane gas produced by ruminants during feed fermentation contributed to global warming as well as poor efficiency of food utilization. Mitigating ruminal methane production through anti-microbial feed additive has serious health implications. A preliminary study of the potential of medicinal plants and spices from Edo and Rivers State, as possible replacement to antibiotic feed additives was carried out. Medicinal plants and spices were purposefully sampled, dried at 40oC, milled and 10 mg was added with 190 mg of substrate in a preweighed nylon incubation bags. Bags and their contents were incubated using 30 mL of buffered rumen liquor in 100 mL syringes following the standard procedure of in vitro fermentation. Variables monitored were 24h total gas volume, short chain fatty acids (SCFA) methane (CH4 ) gas, dry matter degradability (DMD) as well as some chemical, cell wall and anti-nutritive components. Results revealed that adding the medicinal plants and spices as feed additives did not depress gas production in most cases (19.5 – 29.50 mL, 17.75 – 30.00 mL and 12.00 – 29.00 mL for Edo medicinal plants, Edo spices and Rivers medicinal plants respectively) and also did not depress DMD (> 50%). Azadirachta indica stem reduced CH4 production mostly by 53.56% while Dennttia tripetala did by 47.69% among the Edo medicinal plants and spices, respectively. In Rivers State, Amaranthus spinosus gave the highest value of 60.33% CH4 reduction. In the same bracket of similar and good CH4 reduction potentials were Alstonia boonei leaves (49.06%), Newbouldia laevis root (41.50%), Euphorbia heterophyla (37.97%), Allium crispum (47.31%), Allium cepa (46.80%), Aframomum mueguata (46.54%), Capsicum annum (47.32%), Ageratum conyzoides (56.52%), Lagenaria breviflora (48.03%) and Centrosema molle (45.08%). All the medicinal plant and spices with potential for CH4 reduction had corresponding high SCFA values (0.46 – 0.65 Mmol) with tannin (%) and saponin (%) contents of 0.011 – 17.50 and 0.01 – 2.40 respectively. Conclusively, the medicinal plants and spices demonstrated good potentials for reducing rumen methane production in vitro and may be subjected to further in vivo studies.

“…Antibiotics as regulators of ruminal fermentation can generate residues, with detrimental effects on humans, such as resistance to antibiotics (KHACHATOURIANS, 1998;VAN DEN BOGAARD;STOBBERINGH, 2000;DEWULF et al, 2007;DODDS, 2017;GRENNI et al, 2018, JUTKINA et al, 2018. The bioactive compounds of plants present in the essential oils are an alternative for the control of ruminal fermentation (MEDJEKAL et al, 2017;SOLTAN et al, 2018a). The essential oils (EO) contain secondary metabolites with a modulating effect at rumen fermentation (YANG et al, 2007;BENCHAAR et al, 2008;SOLTAN et al, 2018b).…”

“…The essential oils (EO) contain secondary metabolites with a modulating effect at rumen fermentation (YANG et al, 2007;BENCHAAR et al, 2008;SOLTAN et al, 2018b). Bioactive compounds of tropical plants have shown a positive effect in methane depression by up to 25%, without negatively affecting digestibility (MEDJEKAL et al, 2017;SOLTAN et al, 2018a) and ruminal modulation (BABAYEMI et al, 2004;KHOLIF et al, 2018), due to bioactive compounds with antimicrobial effects (AUMEERUDDY-ELALFI et al, 2016). The mechanisms that confer EO their antimicrobial properties are still not well understood (LAMBERT et al, 2001) with evidence of change to the bacterial cell membrane due to changes in electron transport and the ion gradient, in the translocation of proteins, phosphorylation and other enzyme-dependent reactions, similar to ionophores (BURT, 2004).…”

The objective of this study was to determine the effects of essential oils of Anacardium occidentale (Cashew) and Ricinus communis (Castor) on intake, digestibility, ruminal fermentation and excretion of purine derivatives in beef cattle fed high grain diets. Five Nellore steers fitted with ruminal cannula were used in a 5x5 Latin square design (21 days period). The treatments were control MON (0.2 g monensin animal day-1¬) and 1, 2, 4 and 8 g EO animal day-1 (Essential oils - Oligobasics®). All the animals had a basal diet, corn silage-based total mixed ration (TMR) of 80:20 concentrate:forage ratio. Intake, digestibility, ruminal fermentation and excretion of purine derivatives were determined over five consecutive days in each period. Intake and digestibility of dry matter (DM), neutral detergent fibre (NDF) and crude protein (CP) were not influenced by treatments (P > 0.05). However, increasing levels of EO showed a quadratic effect (P < 0.014) above 2 g animal day-1 on the ruminal pH. The excretion of allantoin and uric acid were not influenced by the treatments (P > 0.05), but levels above 2 g day decreased the synthesis of microbial proteins (P < 0.05). It is concluded that the EO of A. occidentale and R. comunnis effectively controlled ruminal fermentation as well as sodium monensin at the studied levels. EOs have the potential to be used in place of monensin in the studied levels.
