Microbial Activity in Bovine Rumen
bengal, asparagus agar (Allen, 1951), asparagus agar plus 1:80,000 crystal violet, and asparagus agar plus 1:15,000 rose bengal. The addition of dyes decreased the number of contaminants but also appeared to inhibit the development of the rhizobia. All plates were examined daily for 2 weeks. Smears of colonies which resembled rhizobia were examined. Pure cultures were obtained by the use of bot...
متن کاملRuminal Protein Degradation and Estimation of Rumen Microbial Protein Production
Animal agricultural production systems are major sources of nonpoint pollution affecting quality of water sources. Nitrogen has been identified as the foremost source of nonpoint water pollution and the potential negative impacts of N have become an area of public concern. protein degradation from feed ingredients is an important factorinfluencing AA supply to the duodenum. Ruminal proteolysis...

متن کاملRumen microbial ecosystem
The inhabitants of the rumen microbial eco-system, a complex consortium of different microbial groups living in symbiotic relationship with the host, act synergistically for the bioconversion of lignocellulosic feeds into volatile fatty acids which serve as a source of energy for the animals. The constraints, imposed by the host and the feed consumed by the animal, under which these microbes ha...
متن کاملInvestigating the Effects of Cadmium on Rumen Microbial Fermentation and Nutrient Digestibility Using Gas Production
Effects of different levels of cadmium (0.1, 1, 2, 4, 8, 16, 32, 64, 128, 256 mg/l of culture medium) were evaluated using gas production technique. In the glass vials used to measure gas production 30 mg of buffered rumen fluid (2:1 ratio of rumen fluid: buffer) poured in glass and cultured at 38.6 temperature. Volume and pressure of produced gas were measured with syringes and digital pressur...
