“…In addition, the effects on reproduction [ 17 ], milk [ 18 ], egg [ 19 ], and meat [ 20 ] quality parameters have been documented. Evidence has shown that PFA may minimize the environmental impact of the livestock industry by reducing emissions into the atmosphere of ammonia from pig production, and methane from fermentation in the rumen [ 21 , 22 ]. Foot dermatitis caused by increased levels of ammonia is used as a parameter to evaluate poultry welfare [ 23 ].…”

The inconsistency of phytogenic feed additives’ (PFA) effects on the livestock industry poses a risk for their use as a replacement for antibiotic growth promoters. The livestock market is being encouraged to use natural growth promotors, but information is limited about the PFA mode of action. The aim of this paper is to present the complexity of compounds present in essential oils (EOs) and factors that influence biological effects of PFA. In this paper, we highlight various controls and optimization parameters that influence the processes for the standardization of these products. The chemical composition of EOs depends on plant genetics, growth conditions, development stage at harvest, and processes of extracting active compounds. Their biological effects are further influenced by the interaction of phytochemicals and their bioavailability in the gastrointestinal tract of animals. PFA effects on animal health and production are also complex due to various EO antibiotic, antioxidant, anti-quorum sensing, anti-inflammatory, and digestive fluids stimulating activities. Research must focus on reliable methods to identify and control the quality and effects of EOs. In this study, we focused on available microencapsulation techniques of EOs to increase the bioavailability of active compounds, as well as their application in the animal feed additive industry.

“…This suggests a potentially crucial role for these components as key biomolecular components to be added to future vaccines against high methanogenesis in the rumen, possibly through their antibacterial (Pollier and Goossens 2012) or anti-proliferative (Neto 2007) activity. However, Banik et al (2016) suggested that rumen microflora can change or adapt over time in response to biserrula substrate; therefore, the short-term bioassay data has to be used with some caution. Ultimately, in vivo and in-field testing is required to confirm these properties.…”

The forage legume species biserrula (Biserrula pelecinus) is among a few forage species with low enteric methane emission when fermented by rumen microbes and it is unclear whether metabolites in biserrula play a role in this. The hypothesis of this study was that specific metabolites in biserrula are candidate biomarkers for and associated with low methanogenesis. We characterized the metabolomic profiles of 30 accessions of biserrula or its core collection using nuclear magnetic resonance and liquid chromatography mass spectrometry. These profiles were then analyzed for association with methanogenesis potential in the rumen. Metabolomic profile was predictive of methanogenesis. Forty-seven putative metabolites were identified by liquid chromatography mass spectrometry that were highly expressed (P < 0.05) in the associations with low methanogenic potential. Fragmentation analysis of a subset of these metabolites suggested saponins, with one feature tentatively identified as an ursolic or oleanolic terpene glucoside, consistent with the nuclear magnetic resonance data. Accessions with Eritrean geographic origin were metabolomic outliers. Here, we show for the first time that some metabolites contribute to the methane mitigation effects of biserrula. If in vivo results confirm this, the environmental impact of this study would be the availability of biomolecules for livestock vaccination to mitigate methane emission resulting in an economic impact of lower cost of production in countries with a price on environmental emissions.

“…Birds-foot trefoil (lotus) was also explored for its potential, and theoretical estimates suggest that it can reduce the CH 4 emission intensity for wool and prime lamb by increasing liveweight gain and fecundity (Doran-Browne et al 2015). For some of the temperate forage species, the mitigation effect may be linked to their primary chemical composition and to enhancing productivity, thus reducing CH 4 emission intensity, whereas in others, such as biserrula, the effect may be linked to the presence of specific anti-methanogenic PSCs (Banik et al 2016).…”

“…In addition to the mainstream species, some alternative forages that are aimed at filling seasonal feed gaps in temperate parts of Australia were also investigated. Local varieties of turnip (Brassica rapa), chicory or plantain (Plantago lanceolata) were found to produce ~25% less CH 4 (mL/g dry matter incubated) in vitro than did lucerne (Durmic et al 2016). Feeding forage brassicas to cattle was found to reduce CH 4 yield (g CH 4 /kg dry-matter intake) by 5%, and CH 4 emission intensity (g/kg energy-corrected milk) by 10% (Williams et al 2016).…”

“…In Australia, extracts from two native forage plants (i.e. Tar Bush or Kennedia prorepens, as well as biserrula), significantly reduced CH 4 production in vitro (Durmic et al 2014;Banik et al 2016). In biserrula, selected fractions were tested against methanogens in pure culture and found to inhibit some key ones, including those found in Australian grazing sheep (Banik et al 2016).…”

This review provides examples of the utilisation of plant bioactivity to mitigate enteric methane (CH 4 ) emissions from the Australian ruminant production systems. Potential plant-based mitigation strategies that reduce CH 4 without major impacts on forage digestibility include the following: (i) low methanogenic tropical and temperate grass, legume and shrub forage species, which offer renewable and sustainable solutions and are easy to adopt, but may have restricted geographical distribution or relatively high costs of establishment and maintenance; (ii) plant-based agricultural by-products including grape marc, olive leaves and fruit, and distiller's grains that can mitigate CH 4 and provide relatively cheap high-nutrient supplements, while offsetting the impact of agricultural waste, but their use may be limited due to unfavourable characteristics such as high protein and water content or cost of transport; (iii) plant extracts, essential oils and pure compounds that are abundant in Australian flora and offer exciting opportunities on the basis of in vitro findings, but require verification in ruminant production systems. The greatest CH 4 mitigation potential based on in vitro assays come from the Australian shrubs Eremophila species, Jasminum didymium and Lotus australis (>80% CH 4 reduction), tropical forages Desmanthus leptophyllus, Hetropogon contortus and Leucaena leucocephala (~40% CH 4 reduction), temperate forages Biserrula pelecinus (70-90% CH 4 reduction), perennial ryegrass and white clover (~20% CH 4 reduction), and plant extracts or essential oils from Melaleuca ericifolia, B. pelecinus and Leptospermum petersonii (up to 80% CH 4 reduction). Further research is required to confirm effectiveness of these plant-based strategies in vivo, determine optimal doses, practical modes of delivery to livestock, analyse benefit-cost ratios and develop pathways to adoption.
