“…Tropical forges have low energy value due to their cell walls contain higher amount of lignin, silica and cutting resulting in lower fermentation of structural carbohydrate [13] and produces less amount of VFA and microbial biomass (microbial protein) after ruminal fermentation in comparison to temperate; b.…”

Anaerobic rumen microorganisms mainly bacteria, protozoa and fungi degrade ligno-cellulosic feeds consumed by the ruminants. The ruminants in developing countries are chiefly maintained on low grade roughage and grazing on degraded range land resulting in their poor nutrient utilization and productivity. Hence, manipulation of rumen fermentation is crucial to optimize ruminal fermentation for improving nutrient utilization and productivity of the animals. Chemical additives those selectively affect rumen microbes, introduction of naturally occurring or genetically modified foreign microbes into the rumen and genetically manipulation of existing microbes in the rumen ecosystem are the available rumen manipulation strategies. Accordingly, rumen protozoa are getting rid of by defaunation for plummeting ruminal methane production and increasing protein outflow in the intestine, resulting in get better growth and feed conversion efficiency of the animals. Additionally, probiotics of bacterial and yeast origin are also used in animal feeding to stabilize rumen fermentation, reduced incidence of diarrhea and thus improving growth and feed conversion efficiency of young stalk. In view of feed resource availability more emphasis must be given for manipulating rumen fermentation to increase cellulolytic activity for efficient utilization of low-grade roughage thereby improves livestock production and productivity.

“…These natural metabolites may affect rumen microbial activity in vitro (Jiménez-Peralta et al, 2011;Salem et al, 2007) and in vivo (Kamel, 2001;Salem et al, 2011a) and improve animal performance (Hart et al, 2008;Salem et al, 2011aSalem et al, , 2014. This group of compounds can modify key ruminal microbial communities (Domínguez-Bello and Escobar, 1997). For example, saponins, a class of the plant natural metabolites, can decrease ruminal ciliate protozoal populations and increase bacterial and fungal biomass (Makkar and Becker, 1997).…”

“…Os fatores metabólicos, também influenciam a produção de metano, compreendidos como a taxa de passagem da digesta, fatores ambientais ligados também à temperatura, manejo dos animais, além de estado fisiológico, tamanho corporal e principalmente a população de microrganismos ruminais como protozoários, bactérias e arqueias (PRIMAVESI et al;. A manipulação direta do rúmen relaciona-se com o uso de aditivos naturais ou químicos, que modificam a fermentação ao terem efeito sobre a microbiota ruminal (DOMINGUEZ;ESCOBAR, 1997 antimicrobianos e propriedades medicinais, mas apenas poucos estudos investigaram as suas propriedades na mitigação de produção dos gases do efeito estufa pela microbiota do rúmen. Os resultados de ensaios experimentais têm mostrado que o óleo essencial de orégano, utilizados em altas concentrações, é um inibidor potente da produção ruminal de CH4, é provavelmente devido à às propriedades antimicrobianas do carvacrol, seu principal composto bioativo (COBELLIS et al, 2015).…”
