“…In the current study, it appears the NFC and fibre fraction influenced in vitro gas and CH4 production more than any other chemical constituent. The result collaborates the reports of (Fluck, et al, 2013;Kulivand and Kafilzadeh, 2015). However, in the present study we opine that the amount of GP24 and CH4 produced generally could not have been as a result of phenolic compounds in the legume seed meals because the source of inoculums is from goat.…”

Background. Increasing atmospheric concentrations of methane (CH4) have led scientists to examine its sources of origin. Mitigation of enteric CH4 production by ruminants has been recognized as an important goal because it reduces greenhouse gas emission and improves feed efficiency. Objective. The study evaluated the chemical composition and its relationship with in vitro total gas (GP24) and in vitro methane (CH4) production parameters of five tropical wild legume seeds [(Luffa cylindrica (LC), Piliostigma thonningii (PT), Detarium microcarpum (DM), Daniellia oliveri (DO) and Afzelia africana (AA)]. Methodology. Chemical compositions were analysed, while total GP volume was measured and CH4 estimated after 24 h incubation. Results. Total GP24 produced by the seeds steadily increased and was most pronounced (P<0.05) in AA seed meal (64.71 mL/200 mg DM), and the least in LC (37.83 mL/200 mg DM). CH4 concentration (MC) varied (P<0.05) from 9.90 in AA to 23.93 in LC. Methane reduction potential (MRP) was higher (P<0.05) for AA seed meal and lowest for LC. There were positive correlations (r = 0.685**, r = 0.763* respectively) between crude protein and non-fibre carbohydrates (NFC) contents of the seeds and total gas production at 24 h incubation. Fibre fractions (NDF and ADF) were positively, (r = 0.978 and r = 0.874 respectively) correlated with MC, and negatively (r = - 0.927 and r = - 0.870, respectively) associated with total GP24 and MRP. CP, EE and NFC had a more pronounced positive correlation (r = 0.948**, r = 0.851** and r = 0.852** respectively) with MRP. Implication. Results suggest that all the selected seeds have the potential to reduce methane production and positively impact rumen fermentation. Conclusion. Seed containing more nutrients (CP, EE, and NFC) reduced enteric methane production more than any other of the chemical components in the study.

“…As observed by Fluck et al (2013), the increase in ADL content causes reduction in bacterial adhesion, total in vitro gas production, and in vitro gas production rate of tropical legumes. The impact of lignin on plant degradability is even greater than the effects of tannin or any other chemical component (Fluck et al, 2013). Although tannins have not been evaluated in this study, they can cause negative effects, mainly on the palatability of the food and complexation with proteins in the rumen (Naumann et al, 2017); however, it can be beneficial for animal performance, in some situations (Waghorn, 2008).…”

“…The digestibility of the fiber fraction in the rumen was hampered by the high concentration of ADL; therefore, lignin content limits cell wall digestibility (Cherney and Mertens, 1998;Raffrenato et al, 2017). As observed by Fluck et al (2013), the increase in ADL content causes reduction in bacterial adhesion, total in vitro gas production, and in vitro gas production rate of tropical legumes. The impact of lignin on plant degradability is even greater than the effects of tannin or any other chemical component (Fluck et al, 2013).…”

Our objective was to identify the best fit mathematical models for in vitro gas production kinetics using rumen fluid and forage plants commonly used in ruminant feed to obtain better estimates of parameters that describe the rumen fermentation. Four mathematical models were tested, two unicompartmental (M1 = first order, M2 = Gompertz) and two bicompartmental (M3 = M1 + M2; M4 = M2 + M2). Two temperate grasses were evaluated, as well as four tropical grasses and three temperate forage legumes. The fit of the models was verified by the corrected Akaike information criterion (AICc r ) and the difference among AICc r values (Δ r ), likelihood probability (W r ), and relative likelihood (ER r ). Temperate forages reached maximum gas production between 48 and 72 h. In the tropical forages, it occurred only after 72 h. In profiles in which M3 was the best choice, the values of parameters V f 1 were higher than those of V f 2 , and k 1 values were higher than k 2 values. The only exception was for Tifton 85 profile, whose V f 2 value was higher than V f 1 . The model M3 has a better fit for tropical forages with higher fiber content and lower levels of nonfibrous carbohydrates and crude protein. The model M1 has a better fit for forage with higher nonfibrous carbohydrate contents and low lignin content.

“…The average CP content (115.90 ± 30.5 g dm³) observed is low (Tabela 2), when compared to a recent Macroptilium lathyroides study (Tobisa & Nakano, 2019) varying from 118 to 250 g dm³ PB, and the plants were evaluated in free growth from 48 to 110 days (Fluck et al, 2013).…”

The objective of the study was to determine the chimical composition of phasey bean throughout the productive cycle. The experiment was carried out in the municipality of Capão do Leão – RS, physiographic south coast region of Rio Grande do Sul. At 45 days after the emergence of the plants, the first cut of the forage evaluation was performed and, at intervals of 15 days, another nine cuts were made, all 5 cm from the soil. The treatments corresponded to different evaluation dates of Macroptilium in free growth in an experiment with ten treatments and three replicates in a completely randomized design. The variables studied were neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), crude protein (PB), total lipids (TL), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg). The results were submitted to analysis of variance and polynomial regression. All variables presented significance (P≤0.05) for cubic regressions, with mean values of: NDF = 58.15; FDA = 38.94; ADL = 9.15; PB = 11.59; TL = 1.18% e; P = 2.29; K = 10.19; Ca = 26.48 and Mg = 4.53 g / kg DM; similar to other hot-legged forage legumes. The bromatological quality of the Macroptilium lathyroides varied during the productive cycle, being directly influenced by the habit of indeterminate growth of the species. From the bromatological quality, the forage of the first growth of the Macroptilium lathyroides should be harvested up to 75 days after emergence, when the lower fiber and lignin contents associated with higher levels of crude protein, lipids, magnesium, and calcium.
