“…Total VFA, acetate, propionate, butyrate and NH 3 ‐N concentrations in the current system were greater than those reported by Noviandi et al () for a 50:50 tall fescue ( Schedonorus arundinaceus (Schreb.) and alfalfa diet fed in continuous culture (50.0 mM, 31.5 mM, 9.91 mM, 5.87 mM, 3.20 mM and 18.7 mg/dl respectively).…”

“…Total VFA, acetate, propionate, butyrate and NH 3 -N concentrations in the current system were greater than those reported by . This is likely due to the greater quality of orchardgrass used in the current study compared with tall fescue used in Noviandi et al (2014). Apparent DM, OM and NDF digestibilities and true DM and OM digestibilities were comparable to Bargo et al (2003) and Soder, Brito, and Rubano (2013) who reported digestibilities of herbage diets in a traditional, dual-flow CCF system; yet, CP digestibility and effluent N-flows were greater in the current study, a result of a greater RDP and CP digestibilities of the orchardgrass/alfalfa diet used.…”

A 4‐unit, single‐flow continuous culture fermenter system was developed to assess in vitro nutrient digestibility, volatile fatty acid (VFA) concentration and daily enteric methane (CH4) production of ruminant diets. The objective was to develop a closed‐vessel system that maintained protozoal populations and provided accurate predictions of total CH4 production. A diet of 50% orchardgrass (Dactylis glomerata L.) and 50% alfalfa (Medicago sativa L.) was fed during 4, 10‐day periods (7‐day adaptation and 3‐day collection). Fermenters were fed 82 g of dry matter (DM)/day in four equal feedings. pH and temperature were taken every 2 min, and CH4 concentration was measured every 10 min. Samples for DM and protozoal counts were taken daily, and daily effluent samples were collected for determination of DM, VFA and NH3‐N concentrations. There was no effect (p > 0.17) of adaptation versus collection days on vessel and effluent DM, temperature or pH. Initial protozoal counts decreased (p < 0.01), but recovered to initial counts by the collection period. Total VFA, acetate, propionate and isobutyrate concentrations did not differ (p ≥ 0.13) among periods or days of the collection period. There was no difference (p ≥ 0.37) among days or periods in total daily CH4 production and CH4 production per g of OM, NDF, digestible OM or digestible NDF fed. Data collected throughout 4 experimental periods demonstrated that the system was able to reach a steady state in fermentation well within the 7‐day adaptation period and even typically variable data (i.e., CH4 production) were stable within and across periods. While further research is needed to determine the relationship between this system and in vivo data, this continuous culture fermenter system provides a valid comparison of in vitro ruminal fermentation and enteric CH4 production of ruminant diets that can then be further validated with in vivo studies.

“…The one exception was PRG-ALF, which yielded 24% more at the first harvest than the PRG mixtures that were greater than in grass monocultures. While we show overall production rates of the grass-BFTF mixtures that are less than those of ALF, their value is enhanced when taking into account the nonbloating characteristics of BFTF, coupled with the reported reduction in ammonia-N and methane production (Noviandi et al, 2014) and the suppression of internal parasites (Hoste et al, 2006).

Well‐managed irrigated pasture production can be optimized without nitrogen (N) fertilizer. The objective was to determine mixture and planting ratios of tall fescue (Schedonorus arundinacea Schreb.) (TF), meadow brome (Bromus riparius Rehm.) (MB), orchardgrass (Dactylis glomerata L.) (OG), timothy (Phleum pratense L.) (TIM), and perennial ryegrass (Lolium perenne L.) (PRG) with alfalfa (Medicago sativa L.) (ALF), birdsfoot trefoil (Lotus corniculatus L.) (BFTF), or cicer milkvetch (Astragalus cicer L.) (CMV) that maximize productivity. Planting ratios were 0:100 (grass:legume), 25:75, 50:50, 75:25, and three 100:0 grass monocultures fertilized at 0, 67, and 134 kg N ha−1. Seasonal production of TF–ALF was 12.69 Mg ha−1, equal to TF fertilized at 134 kg N ha−1. ALF mixtures with MB, OG, TIM, and PRG produced 12.57, 10.97, 11.77, and 10.74 Mg ha−1, respectively, and 8 to 40% more than grasses receiving 134 kg N ha−1. Production of BFTF mixtures with TF, MB, and OG were 11.69, 11.45, and 9.95 Mg ha−1, respectively, equal to their respective grass monoculture receiving 134 kg N ha−1. The BFTF–TIM and BFTF–PRG mixtures averaged 12% more forage than grass monocultures receiving 134 kg N ha−1. Production of CMV‐grass was similar to that of grasses receiving 67 kg N ha−1. Seasonal forage distribution was more uniform in ALF– and BFTF–grass mixtures, averaging 30% more at the second and third harvests than fertilized grasses. The TF and MB legume mixtures averaged 7% more production in the 50:50 planting ratios than the other two grass–legume mixtures, while the 50:50 and 25:75 ratios of OG and TIM–legume mixtures averaged 12% more than the 75:25 and the 25:75 PRG–legume planting ratio averaged 9% more than the 50:50 and 75:25. Forage production of grass–legume mixtures can equal or exceed fertilized grass monocultures and with more uniform distribution over the growing season.

“…Due to concerns with frothy bloat for cattle grazing monoculture ALF, research evaluating bloat-safe legumes, such as SAIN and CMV, has increased (McMahon et al 1999;Williams et al 2011;Stewart et al 2019). Cicer milkvetch is bloat-safe due to its reticulate veined leaf pattern and thick epidermal layers that slow ruminal microbial digestion and have been reported to reduce ruminal NH 3 -N concentration, reduce CH 4 production, and shift N excretion from urine to faeces (Lees et al 1982;Williams et al 2011;Noviandi et al 2014;Stewart et al 2019). Conversely, legumes, such as SAIN and birdsfoot trefoil, are bloat-safe and modulate rumen fermentation due to condensed tannins (CT) in plant tissues, which can increase host protein utilization and confer anti-parasitic properties (Min and Solaiman 2018;Mueller-Harvey et al 2019).…”

Effect of mixtures of legume species on ruminal fermentation, methane, and microbial nitrogen production in batch and continuous culture (RUSITEC) systems

The effect of cicer milkvetch (Astragalus cicer L.) and sainfoin (Onobrychis viciifolia Scop.) on ruminal fermentation, methane production, and microbial nitrogen synthesis was assessed in two experiments. Experiment 1 analyzed 2 legumes, cicer milkvetch and sainfoin at 2 stages (vegetative and late flower) incubated with alfalfa (Medicago sativa) at 5 inclusion rates 0:100; 25:75, 50:50, 75:25 and 100:0 (as DM) in batch culture. Experiment 2 analyzed vegetative cicer milkvetch and alfalfa incubated in ratios of 25:75, 50:50, 75:25 and 100:0 (as DM) in continuous culture systems (RUSITEC). In batch culture, increased dry matter disappearance (DMD), and propionate percentage (%, total), and reduced methane (mg g-1 DMD) occurred with vegetative cicer milkvetch inclusion. In RUSITEC, DMD linearly increased (P < 0.01), acetate:propionate ratio quadratically decreased, while ammonia (NH3-N) concentration (P<0.01) and butyrate percentage (% total) linearly decreased (P<0.05) with increasing inclusion of cicer milkvetch. No differences were observed for methane (CH4) production (mg g-1 DMD), or short chain fatty acid (SCFA) production (mmol d-1). Microbial nitrogen synthesis and efficiency of protein synthesis linearly increased (P<0.05) with increased inclusion of cicer milkvetch. Results suggest cicer milkvetch may result in synchronicity of energy and nitrogen during rumen fermentation, which could enhance cattle production.
