“…For example, VFA concentration and its relative proportions, which mainly influence methane production, are influenced by the nature and fermentation of carbohydrate (Johnson and Johnson 1995). The positive correlation between methane production and cellwall contents (NDF, ADF, cellulose and lignin) observed in this study is in agreement with previous reports (Moss 2000;Singh et al 2012). The negative correlation between CP and methane production is in agreement with the finding of Moss (2000).…”

“…This finding is in agreement with previous finding of Johnson and Johnson (1995), who identified that carbohydrate fed to livestock has a major effect on methane production, most likely because of the effect on rumen pH and its microbial population. Similar to this finding, Santoso et al(2007) and Singh et al(2012) indicated that carbohydrate fractions (NDF and ADF) are better methane predictors than feed components.…”

“…We assume that the higher values in our report than for temperate conditions (Getachew et al 2005) might be attributed to relatively higher levels of fibre and lignin (Van Soest 1994) recorded for dry season harvested grasses (Table 1) and associated low values of digestibility, and due to the lower digestibility (13%) of most tropical grasses compared with temperate grasses (Minson 1990). Similar to our report, there are many findings showing that methane production could be influenced by the contents and nature of cell wall digested (NDF, ADF, ADL, cellulose, and hemicelluloses) (Santoso et al 2003(Santoso et al , 2007Singh et al 2012). This is because the OM digestion, fermentation and production of short-chain VFAs of forages are mainly dependent on their structural factors and the relative proportion of cell types present in their tissues, and the existence of factors restricting microbial access to walls (Van Soest 1994).…”

“…Mitigation of methane production from ruminants by altering the diet is an effective way to decrease enteric methane production (Singh et al 2012). An increased proportion of concentrate in ruminant rations is generally associated with a reduction in methane emission per unit of feed intake and per unit of animal product (Johnson and Johnson 1995;Lovett et al 2003).…”

Abstract. This study characterised 16 tropical perennial grass species in terms of in vitro methane output and related their digestibility and rumen fermentation with methane output. The grass samples were collected, dried in a forced oven, and ground and analysed for nutrient composition. In vitro gas production and organic matter digestibility (IVOMD) were determined using rumen fluid collected, strained and anaerobically prepared. A semi-automated system was used to measure gas production through in vitro incubation at 398C. Anthephora argentea and Stipagrostis ciliate produced the highest concentration of methane in terms of g kg -1 digestible dry matter (DDM) and g kg -1 digestible organic matter (IVOMD). Cenchrus ciliaris, Setaria verticillata and Panicum coloratum produced the lowest (P < 0.05) methane when expressed in terms of g kg -1 DDM and g kg -1 IVOMD. Ash, ether extract, non-fibrous carbohydrate, neutral and acid detergent insoluble nitrogen, and crude protein were negatively correlated with methane production. Methane production positively correlated with neutral and acid detergent fibre, cellulose and hemicellulose. It is important to focus on screening and selecting perennial grass with higher nitrogen content and low methane production to mitigate methane production under tropical conditions.

“…Although the species were not affected by the addition of PEG, A. amentacea, was numerically higher (8.5 mol) than P. texana (6.9 mol), which indicates that this legume was more efficient in microbial protein production than A. amentacea. Reduced values of purines can be attributed to the presence of CT and other chemical compounds that likely inhibit fermentation, which might affect the degradation of substrates (Singh et al, 2012). Both P. texana and A. amentacea were high in NSC (20 and 30%, respectively) which suggest that negative effects of tannins on microbial growth, may be overcome if readily fermentable carbohydrates are present (Mbugua et al, 2008).…”

In order to evaluate the nutritional value of Parkinsonia texana and Acacia amentacea, two leguminosae species of the Tamaulipan scrubland, Northeastern Mexico, two experiments were carried out: the first tested the effects of season and browse species on chemical composition as nutritional variable to small ruminants; the second tested the effect of the addition of polyethylene glycol (PEG) on fermentation parameters. Foliage samples were collected from three sites. Data of chemical composition were analysed using analysis of variance for a bi-factorial arrangement, whereas the effect of PEG was analysed by a strip plot design. Results of chemical composition were affected by interacting factors season*species as individually they were significantly different (P<0.001). Addition of PEG affected (P<0.001) fermentation parameters. Significantly higher values of neutral detergent fibre (42%), condensed tannins (19%), purines (9 mol), partitioning factor (PF) (6.1) and gross energy losses (GEL=6.7%) were found in A. amentacea, while P. texana gave higher crude protein (18%), in vitro true organic matter digestibility (82%), metabolisable energy (ME) [2.1 Mcal/kg dry matter (DM)], A (183 mL), c (0.07/h) and L (0.86 h). Addition of PEG increased ME, and affected (P<0.001) fermentation parameters A and c, while purines and PF decreased. Results indicate that chemical composition and fermentation parameters vary according to seasons and species. PEG addition increases the fermentation parameters, which indicates that PEG counteracts the detrimental effects of secondary components of samples. Data suggest that using both species combined could supply necessary nutritional requirements to small ruminants in the Tamaulipan scrubland.

BACKGROUND Information about the nutritive value, dry matter (DM) digestibility, and methane (CH4) emission potential of grass species is required for their optimal utilization in ruminant rations. The present study was designed: (i) to quantify the nutrient profile, mineral composition and in vitro dry matter digestibility (IVDMD) of winter grass species commonly available in northern Pakistan; and (ii) to measure the in vitro gas production (IVGP) and CH4 emission of the grass species during 72 h in vitro ruminal fermentation. Seven grass species, namely, Cenchrus ciliaris, Setaria anceps, Panicum antidotale, P. maximum, Pennisetum purpureum, Pennisetum orientale, and Atriplex lentiformis were assessed. RESULTS A high level of variability (P < 0.001) was observed among grass species for the content of all measured nutrients, IVDMD, IVGP, and CH4‐production. Notably, the content (g kg−1 DM) of crude protein varied from 59.8 to 143.3, neutral detergent fiber from 560.3 to 717.9, IVDMD from 375.1 to 576.2, and 72 h cumulative IVGP from 97.6 to 227.4 mL g−1 organic matter (OM) and CH4 from 48 to 67 mL g−1 OM. Among the grasses, P. antidotale had greater content (g kg−1 DM) of crude protein (CP) (143.3), IVDMD (576.2), and 72 h cumulative IVGP (227.4 mL g−1 OM), and produced the smallest amount of total CH4 (48 mL g−1 OM) during 72 h fermentation. In contrast, A. lentiformis had the lowest content (g kg−1 DM) of CP (59.8), IVDMD (375.1), 72 h cumulative IVGP (97.6 mL g−1 OM), and produced a greater amount of total CH4 (67 mL g−1 OM) during 72 h fermentation. CONCLUSION The findings of the current study highlight that it is possible to select and further develop grass species with high nutritional value and lower CH4‐production, which can improve livestock productivity, farm profitability, and long‐term environment sustainability. © 2020 Society of Chemical Industry
