“…Increased propionate production could be explained by the reduction of Gram-positive bacteria [37]. Changes in molar proportions of VFA in the rumen when chitosan is used as a feed additive is conducive toward an improvement in the efficiency of utilization of metabolizable energy for growth ( k f ) [61] , which may lead to better animal performance and reduction in methane synthesis [62]. Thus, chitosan seems to work in the rumen much in the way as when grain (starch) is incorporated in the ration, by shifting the pattern of fermentation to a more propionic acid type of fermentation.…”

Simple SummaryRuminant husbandry is one the largest contributors to greenhouse gas emissions from the agriculture sector, particularly of methane gas, which is a byproduct of the anaerobic fermentation of structural and non-structural carbohydrates in the rumen. Increasing the efficiency of production systems and decreasing its environmental burden is a global commitment, thus methane mitigation is a strategy in which to reach these goals by rechanneling metabolic hydrogen (H2) into volatile fatty acids (VFA) to reduce the loss of energy as methane in the rumen, which ranges from 2% (grain rations) to 12% (poor-quality forage rations) of gross energy intake. A strategy to achieve that goal may be through the manipulation of rumen fermentation with natural compounds such as chitosan. In this review, we describe the effects of chitosan on feed intake and rumen fermentation, and present some results on methanogenesis. The main compounds with antimethanogenic properties are the secondary metabolites, which are generally classified into five main groups: saponins, tannins, essential oils, organosulfurized compounds, and flavonoids. Novel compounds of interest include chitosan obtained by the deacetylation of chitin, with beneficial properties such as biocompatibility, biodegradability, non-toxicity, and chelation of metal ions. This compound has shown its potential to modify the rumen microbiome, improve nitrogen (N) metabolism, and mitigate enteric methane (CH4) under some circumstances. Further evaluations in vivo are necessary at different doses in ruminant species as well as the economic evaluation of its incorporation in practical rations.AbstractLivestock production is a main source of anthropogenic greenhouse gases (GHG). The main gases are CH4 with a global warming potential (GWP) 25 times and nitrous oxide (N2O) with a GWP 298 times, that of carbon dioxide (CO2) arising from enteric fermentation or from manure management, respectively. In fact, CH4 is the second most important GHG emitted globally. This current scenario has increased the concerns about global warming and encouraged the development of intensive research on different natural compounds to be used as feed additives in ruminant rations and modify the rumen ecosystem, fermentation pattern, and mitigate enteric CH4. The compounds most studied are the secondary metabolites of plants, which include a vast array of chemical substances like polyphenols and saponins that are present in plant tissues of different species, but the results are not consistent, and the extraction cost has constrained their utilization in practical animal feeding. Other new compounds of interest include polysaccharide biopolymers such as chitosan, mainly obtained as a marine co-product. As with other compounds, the effect of chitosan on the rumen microbial population depends on the source, purity, dose, process of extraction, and storage. In addition, it is important to identify compounds without adverse effects on rumen fermentation. The present review is aimed at providing in...

“…In this experiment the rechannelling of H 2 toward propionate synthesis in the rumen, was the most plausible explanation for the decrease in methane emissions. Foliage and pods (45) of Samanea saman show good potential to mitigate enteric methane emissions under practical conditions in farms as part of the ration of grazing ruminants, particularly during the dry season. Similarly, Enterolobium cyclocarpum (in Spanish: guanacaste, parota) is a tropical tree which produce foliage and pods which can be employed in ruminant feeding.…”

“…They concluded that saponins in Samanea saman contributed to alter the rumen microbiome by decreasing protozoa and probably methanogenic archaea with the resultant decrease of up to 50% in CH 4 synthesis. Valencia-Salazar et al ( 45 ) fed crossbred heifers housed in respiration chambers with ground pods of Samanea saman at different levels and demonstrated a reduction in enteric CH 4 production of up to 50% and an increase in propionic acid in rumen liquor, although no effect on the rumen protozoal population was recorded. In this experiment the rechannelling of H 2 toward propionate synthesis in the rumen, was the most plausible explanation for the decrease in methane emissions.…”

“…Se ha demostrado que una forma para mitigar las emisiones de GEI provenientes de la fermentación entérica es la inclusión de granos en la alimentación de rumiantes, ya que éstos reducen la producción de ácido acético en el rumen y consiguen un descenso en las cantidades emitidas de CH 4 (Valencia-Salazar et al, 2018). Otra forma para mitigar las emisiones de GEI en condiciones de pastoreo es la selección de rumiantes con menores requerimientos energéticos, mayor conversión alimenticia y ciclos productivos menos prolongados; cualidades que le confieren al sistema una mayor productividad por unidad de superficie, principio en el que se sustenta la intensificación de la ganadería (Steinfeld et al, 2006;Beauchemin et al, 2009).…”

La demanda presente y futura de alimentos ocasionada por el crecimiento de la población requiere de un mayor grado de intensificación de los sistemas productivos, pero en el caso de la ganadería su desarrollo ha implicado cambios en el uso del suelo y deterioros ambientales. Por lo tanto, la producción de carne y leche debe no superar los límites de uso de los recursos naturales y mitigar el deterioro ambiental ocasionado. El principal efecto asociado a la actividad ganadera es la emisión de gases de efecto invernadero, misma originada por la deforestación para el establecimiento de áreas de pastoreo y cultivos forrajeros, así como de la fermentación entérica de los ganados. Esta problemática requiere un análisis de la interacción ganadería-ambiente y la validación de herramientas tecnológicas idóneas para la mitigación del deterioro ambiental. En este sentido, este documento brinda información sobre alternativas de intensificación sostenible de los sistemas de producción bovina, enfatizando en sistemas pastorales de países en vías de desarrollo. Los objetivos de este artículo de revisión, son: a) realizar una síntesis comparativa de las emisiones de gases de efecto invernadero atribuidas a la intensificación de la ganadería bovina en países desarrollados y en vías de desarrollo y, b) proponer como elementos básicos de los sistemas silvopastorales la integración de árboles, arbustos y razas locales para la mitigación de los deterioros ambientales en zonas tropicales de América Latina.
