“…In addition, the PHA allowed a reduction of genera Ruminiclostridium 6, Ruminococcaceae UCG-010, and Lachnospiraceae uncultured belonging to the Firmicutes phylum, Clostridiales order, and typical of cellulolytic bacteria [66]. This deleterious effect of PHA also was observed in the rumen of steers supplemented with EPHA, which had a lower relative abundance of both genera Roseburia, Family XIII UCG-002, and the Veillonellaceae family, and may be associated with the lower total digestibility of DM observed with the addition of PHA in this study and the lower fiber digestibility observed by Teobaldo et al [22] in performance trial. Witzig et al [8] also observed a reduction in the relative abundance of Ruminococcus albus by chestnut and valonea tannins.…”

“…This can be justified by the sulfur content of the corn gluten meal, due to the industrial process for obtaining that uses sulphited water in one of its stages, because many Archaea use sulfur compounds as electron donors or acceptors for energy production [68]. This also is in line with the increase in the enteric CH4 daily production reported in grazing beef cattle when supplemented with energy supplements [22]. In contrast, Methanobrevibacter abundance was reduced when 1.5 g of hydrolyzable tannins were evaluated in vitro [7], indicating that tannin extract also can affect the archaea population in the rumen.…”

“…A blend of essential oils, bioflavonoids, and tannins improved diet digestibility and feed conversion rate in dairy cattle [21]. But the association of hydrolyzable tannins and essential oils during the supplementation of grazing beef cattle resulted in a negative effect on forage intake and digestibility [22].…”

“…Marandu, delimited by electric fencing and served by a trough with access from both sides (30 cm linear per animal) and a drinking fountain. The meteorological data and maintenance of fertilization in the experimental area during the experimental period were described by Teobaldo et al [22]. Pastures were managed under continuous stocking with variable stocking rates and a canopy target of approximately 25 cm high, using the "put and take" technique [24], and animals' regulators to adjust and maintain the height target, in addition to the steers testers.…”

The objective of this study was to evaluate the effect of the addition of a phytogenic compounds blend (PHA) containing hydrolyzable tannins, carvacrol and cinnamaldehyde oil in the mineral salt or energy supplement on the rumen microbiota and nitrogen metabolism of grazing Nellore cattle. Eight castrated Nellore steers were distributed in a double Latin square 4 × 4 design, with a 2 × 2 factorial arrangement (two type supplements and the addition or not of PHA) as follows: energy supplement without PHA addition (EW); energy supplement with PHA addition (EPHA); mineral supplement without the addition of PHA (MW); and mineral supplement with PHA addition (MPHA). Steers that received supplements with PHA have a lower ruminal proportion of Valerate (with PHA 1.06%; without PHA 1.15%), a lower ruminal abundance of Verrucomicrobia and a tendency for lower DM digestibility (with PHA 62.8%; without PHA 64.8%). Energy supplements allowed higher ammonia concentrations (+2.28 mg of NH3-N/dL), increased the propionate proportion (+0.29% of total VFA), and showed a tendency to have a higher abundance of Bacteroidetes and a lower abundance of Firmicutes in the rumen. The PHA addition in the supplement did not improve the use of nitrogen in grazing cattle, but negatively affected the diet digestibility.

The PHA addition in the supplement did not improve nitrogen retention, reduced the ruminal proportion of valerate, and had a negative impact on both the total dry-matter digestibility and the abundance of several ruminal bacterial groups belonging to the Firmicutes and Verrucomicrobia phyla.

Beef Steers and Enteric Methane: Reducing Emissions by Managing Forage Diet Fiber Content

Understanding the methane (CH4) emissions that are produced by enteric fermentation is one of the main problems to be solved for livestock, due to their GHG effects. These emissions are affected by the quantity and quality of their diets, thus, it is key to accurately define the intake and fiber content (NDF) of these forage diets. On the other hand, different emission prediction equations have been developed; however, there are scarce and uncertain results regarding their evaluation of the emissions that have been observed in forage diets. Therefore, the objectives of this study were to evaluate the effect of the NDF content of a forage diet on CH4 enteric emissions, and to evaluate the ability of models to predict the emissions from the animals that are consuming these forage diets. In total, thirty-six Angus steers (x¯ = 437 kg live weight) aged 18 months, blocked by live weight and placed in three automated feeding pens, were used to measure the enteric CH4. The animals were randomly assigned to two forage diets (n = 18), with moderate (<50%, MF) and high (>50%, HF) NDF contents. Their dry matter intake was recorded individually, and the CH4 emissions were measured using the SF6 tracer gas technique. For the model evaluation, six prediction equations were compared with 29 studies (n = 97 observations), analyzing the accuracy and precision of their estimates. The emission intensities per unit of DMI, per ADG, and per gross energy intake were significantly lower (p < 0.05) in the animals consuming the MF diet than in the animals consuming the HF diet (21.7 vs. 23.7 g CH4/kg DMI, 342 vs. 660 g CH4/kg ADG, and 6.7% vs. 7.5%, respectively), but there were no differences in the absolute emissions (p > 0.05). The best performing model was the IPCC 2006 model (r2 = 0.7, RMSE = 74.04). These results show that reducing the NDF content of a forage diet by at least 10% (52 g/kg DM) reduces the intensity of the g CH4/kg DMI by up to 8%, and that of the g CH4/kg ADG by almost half. The use of the IPCC 2006 model is suitable for estimating the CH4 emissions from animals consuming forage-based diets.
