“…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.…”

“…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).…”
