Influence of exogenous fibrolytic enzymes and fumarate on methane production, microbial growth and fermentation in Rusitec fermenters.
Two incubation runs were conducted with Rusitec fermenters to investigate the effects of three additive treatments (mixed fibrolytic enzymes from Trichoderma longibrachiatum (FE), disodium fumarate (FUM) and both additives (MIX)) on rumen microbial growth and fermentation of a grass hay:concentrate (600 : 400 g/kg DM) substrate. Each fermenter received daily 20 g substrate DM. Application rate ...
متن کاملEffects of exogenous cellulase supplementation on microbial growth and ruminal fermentation of a high-forage diet in Rusitec fermenters.
Two incubation runs were carried out with a Rusitec system to investigate the effects of 2 exogenous pure cellulases on ruminal microbial growth and fermentation of a 70:30 grass hay:concentrate (DM basis) substrate. The substrate was sprayed with buffer (control; pH = 6.5), a cellulase from Trichoderma longibrachiatum (TRI), a cellulase from Aspergillus niger (ASP), or a 1:1 mixture of both ce...
متن کاملIn vitro Effects of Exogenous Fibrolytic Enzymes on Rumen Fermentation of Wild Guinea Grass (Panicum maximum)
This study aimed to evaluate the potential of commercial enzymes cellulase (CE), xylanase (XY) and the combination of CE + XY to improve rumen fermentation of Guinea grass ecotype ‘A’ (Panicum maximum). The experiment was carried out in a randomized complete block design. In vitro incubations were performed with four doses of individual enzymes and their combinations (1:1 from each enzyme) as 5...
متن کاملInfluence of Fibrolytic Enzymes on the in vitro Hydrolysis and Fermentation of Different Types of Roughages Treatment
The effects of pre-treating different types of roughages with alkali on the efficacy of exogenous fibrolytic enzymes for improving their digestibility were studied in vitroin factorial arrangement 4 × 3 × 5 (enzyme, treatment and roughage types). Two fibrolytic feed enzymes novozyme (N) and celloclast (C) their combination (N+C) were evaluated for their potential to improve in vitrodegradation ...
متن کاملThe Effects of Phenolic Compounds in Iranian Propolis Extracts on in vitro Rumen Fermentation, Methane Production and Microbial Population
The objective of this study was to determine the chemical compounds of Iranian propolis (IP) extracts and to show flavonoids and phenol effects on methane production, fermentation characteristics and rumen microbial population (in vitro). In this study two diets with different concentrate: forage ratios as (HC: high concentrate) and (MC: middle concentrate), respectively as non-supplemented or ...
