Effect of the magnitude of the decrease of rumen pH on rumen fermentation in a dual-flow continuous culture system.
The negative effect of pH on rumen microbial fermentation has been associated with the total amount of time that pH is below a certain threshold. However, not only the time, but also the magnitude of the pH reduction, is important. Eight 1,325-mL dual-flow continuous culture fermenters were used in 2 replicated periods to determine the effect of the magnitude of pH reduction (5.6 vs. 5.1) durin...
متن کاملRuminal microbial fermentation of dromedary camel in a dual flow continu-ous culture system using cultivable and pasture forages
In this experiment eight 1,600 mL dual-flow continuous culture fermenters were used to measure the fermentation pattern of cultivable and pasture forages in camel. Two adult camels were used as rumen inocula donors. Fermenters were fed with 120 g of DM/d in 3 equal portions at 08:00, 16:00, and 24:00 h. The trial contained two treatments of four replicate each in a completely randomized design....
متن کاملEffects of Thyme Essential Oil and Disodium Fumarate on Ruminal Fermentation Characteristics, Microbial Population and Nutrient Flow in a Dual Flow Continuous Culture System
The aim of the present study was to investigate the effects of di-sodium fumarate (DSF) and thyme essential oil (TEO) solely and simultaneously on ruminal fermentation properties and microbial abundance. A dual-flow continuous culture system (DFCC) with eight 1400-mL fermenters was used in a period of 12 d that divided to 9 d for adaptation and 3 d for sampling. Fermenters were fed 100 g d...
متن کاملSimultaneous Amplicon Sequencing to Explore Co-Occurrence Patterns of Bacterial, Archaeal and Eukaryotic Microorganisms in Rumen Microbial Communities
Ruminants rely on a complex rumen microbial community to convert dietary plant material to energy-yielding products. Here we developed a method to simultaneously analyze the community's bacterial and archaeal 16S rRNA genes, ciliate 18S rRNA genes and anaerobic fungal internal transcribed spacer 1 genes using 12 DNA samples derived from 11 different rumen samples from three host species (Ovis a...
متن کاملinvestigating the effects of salvia mirzayanii essential oil on rumen microbial fermentation and nutrient digestibility using gas production and dual flow continuous culture system
this study was conducted to investigate the effects of different doses of salvia mirzayanii essential oils on gas production parameters, fermentation characteristics using gas production and dual flow continuous culture system. trearments in the gas production experiment was adding 0, 400, 800, 1200, 1600, 2000, 2400 and 4800 mg/l of salvia mirzayanii essential oils to the media. in the second ...
