“…It has been reported that cattle with higher consumption of organic matter are associated with a greater physiological capacity of the rumen, longer retention times, and higher digestion rates, increasing CH 4 production (58,59). Similar findings were observed in the current study, where the amount of CH 4 that was emitted was related to the DMD (Figure 2A), NDF (Figure 2B), and ADF intake (Figure 2C).…”

“…In addition, Montenegro et al (65) also observed reductions in CH 4 emissions of 25% (31 vs. 23 g CH 4 kg DMI −1 ) when the animals consumed more DM of high-quality diets. It has been reported that CH 4 emissions can increase as a result of increased DMI, but the intensity of emissions per unit product would also be reduced (17,58,60,66) probably as a result of the better nutritional quality and digestibility of these diets (58,(67)(68)(69). These observations show the importance of adequately managing grazing and browsing regimes of forages as this could influence not only DMI but also CH 4 emissions.…”

Methane (CH 4 ) emissions from enteric fermentation in cattle are an important source of greenhouse gases, accounting for about 40% of all agricultural emissions. Diet quality plays a fundamental role in determining the magnitude of CH 4 emissions. Specifically, the inclusion of feeds with high digestibility and nutritional value have been reported to be a viable option for reducing CH 4 emissions and, simultaneously, increase animal productivity. The present study aimed to evaluate the effect of the nutritional composition and voluntary intake of diets based on tropical forages upon CH 4 emissions from zebu steers. Five treatments (diets) were evaluated: Cay1: Urochloa hybrid cv. Cayman (harvested after 65 days of regrowth: low quality); Cay2: cv. Cayman harvested after 45 days of regrowth; CayLl: cv. Cayman + Leucaena leucocephala; CayLd: cv. Cayman + Leucaena diversifolia; Hay: Dichantium aristatum hay as a comparator of common naturalized pasture. For each diet representing different levels of intensification (naturalized pasture, improved pasture, and silvopastoral systems), CH 4 emissions were measured using the polytunnel technique with four zebu steers housed in individual chambers. The CH 4 accumulated was monitored using an infrared multigas analyzer, and the voluntary forage intake of each animal was calculated. Dry matter intake (DMI, % of body weight) ranged between 0.77 and 2.94 among diets offered. Emissions of CH 4 per kg of DMI were significantly higher (P < 0.0001) in Cay1 (60.4 g), compared to other treatments. Diets that included Leucaena forage legumes had generally higher crude protein contents and higher DMI. Cay1 and Hay which had low protein content and digestibility had a higher CH 4 emission intensity (per unit live weight gain) compared to Cay2, CayLl and CayLd. Our results suggest that grass consumed after a regrowth period of 45 days results in lower CH 4 emissions intensities compared to those observed following a regrowth period of 65 days. Diets with Leucaena inclusion showed Gaviria-Uribe et al.Methane From Cattle Tropical-Forages advantages in nutrient intake that are reflected in greater live weight gains of cattle. Consequently, the intensity of the emissions generated in the legume-based systems were lower suggesting that they are a good option for achieving the emission reduction goals of sustainable tropical cattle production.

“…Several meta-analyses of the literature found that 10 g/kg DM addition of lipid to the diet reduces CH 4 yield (g/kg DMI) by up to 5.6% [20,[22][23][24]. The microbial basis with which dietary lipids decrease methanogenesis is not fully understood but is thought to be due to: 1) a decrease in the amount of organic matter fermented in the rumen; 2) a decrease in the abundance of rumen methanogens and protozoa; and 3) provision of alternative H 2 sinks through biohydrogenation of unsaturated fatty acids [20].…”

Background: The major GHG from ruminants is enteric methane (CH4) which in 2010, was estimated at 2.1 Gt of CO2 equivalent, accounting for 4.3% of global GHG emissions. There re extensive efforts being made around the world to develop methane mitigating inhibitors that specifically target rumen methanogens with the ultimate goal of reducing the environmental footprint of ruminant livestock production. This study examined the individual and combined effects of supplementing a high-forage diet (90% barley silage) fed to beef cattle with the investigational methane (CH4) inhibitor 3-nitrooxypropanol (3-NOP) and canola oil (OIL) on the rumen microbial community in relation to enteric CH4 emissions and ruminal fermentation.Results: 3-NOP and OIL individually reduced enteric CH4 emission (-28.2% and -24.0%, respectively), and the effects were additive when used in combination (-51.3%). 3-NOP increased H2 emissions 37 fold, while co-administering 3-NOP and OIL increased H2 in the rumen 20-fold relative to the control diet. The inclusion of 3-NOP or OIL reduced the diversity of the rumen microbiome. 3-NOP resulted in targeted changes in the microbiome decreasing the relative abundance of Methanobrevibacter and increasing the relative abundance of Bacteroidetes. The inclusion of OIL resulted in large scale changes to the microbial community that were associated with changes in ruminal volatile fatty acid concentration and gas production. OIL significantly reduced the abundance of protozoa and fiber-degrading microbes in the rumen but it did not selectively alter the abundance of rumen methanogens.Conclusions: Our data provide a mechanistic understanding of CH4 inhibition by 3-NOP and OIL when fed alone and in combination to cattle. 3-NOP specifically targeted rumen methanogens inhibiting the hydrogenotrophic methanogenesis pathway and resulting in increased H2 emissions and propionate production. In contrast, OIL caused large scale changes in the rumen microbial community by indiscriminately altering the abundance of a range of rumen microbes, reducing the abundance of fibrolytic bacteria and altering rumen fermentation. Importantly, our data suggests that co-administering CH4 inhibitors with distinct mechanisms of action can both enhance CH4 inhibition and provide alternative sinks to prevent excessive accumulation of ruminal H2.
