Modifications of a Device for Maintenance of the Rumen Microbial Population in Continuous Culture.
An improved and simplified apparatus for maintaining the rumen microbial population in continuous culture was constructed. All components were easily obtained from commercial sources or were simple to construct. Mechanical difficulties were minimal, and little attention was needed on the part of the operator. The deoxyribonucleic acid (DNA) content of the cultures (100 to 150 mug/ml) varied lit...
متن کاملEffect of Protein Sources on Rumen Microbial Protein Synthesis Using Rumen Simulated Continuous Culture System
A rumen simulated continuous culture (RSCC) system was used to study the influence of supplementation of the three different types of protein sources such as urea, casein and soy protein on rumen microbial synthesis in terms of rumen microbial synchronization. The urea treatment showed the highest pH value. Ammonia nitrogen concentration was rapidly increased after feeding and not significantly...
متن کاملRumen degradable protein supply affects microbial efficiency in continuous culture and growth in steers.
We hypothesized that microbial efficiency and output from fermentation in the rumen would be optimized when peptide supply was balanced with peptide requirement of ruminal microflora. This study was conducted to measure response of varying rumen degradable peptide (RDPep) supply on ruminal fermentation characteristics and steer growth. A continuous culture experiment was conducted with diets fo...
متن کاملMaintenance of a certain rumen protozoal population in a continuous in vitro fermentation system.
A continuous culture system suitable for maintaining certain rumen protozoa was developed by modifying the procedure of Walter and Pilgrim (R.A. Weller and A.F. Pilgrim, Br. J. Nutr. 32:341-351, 1974) to include a dialyzing system. The concentration of ciliate protozoa, the pH value, and concentrations of volatile fatty acid and ammonia-N could be maintained within normal rumen limits for more ...
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 ...
