I . The deamination, ureolytic and proteolytic activities and rates of cellulolysis and gas production in large intestinal contents have been compared with those activities and rates in rumen contents of sheep. 2. Large intestinal contents produced ammonia. The rate of ammonia production was greater in caecal contents than in faeces. Incubation of caecal contents under toluene resulted in decre...
The ability of ruminal microorganisms to degrade octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (high melting explosive, HMX) as consortia from whole rumen fluid (WRF), and individually as 23 commercially available ruminal strains, was compared under anaerobic conditions. Compound degradation was monitored by high-performance liquid chromatography, followed by liquid chromatography-tandem mas...
This research was conducted to investigate the effects of feeding of barley grain (whole or cracked) combined with two different protein sources (urea or soybean meal) on nutrients digestibility and rumen parameters (pH and ammonia concentration). Four rumen fistultated Mehraban sheep was used that the mean body weight of sheep was 36.5±0.5 kg. The the experiment was conducted in change over de...
The rumen microbiome is integral to efficient production in cattle and shows strong host specificity, yet little is known about what host factors shape rumen microbial composition. Secretory immunoglobulin A (SIgA) is produced in large amounts in the saliva, can coat both commensal and pathogenic microbes within the gut, and presents a plausible mechanism of host specificity. However, the role ...
Ruminants are unique mammals that can convert the energy in roughage to edible products for humans. Hence, rumen fermentation has been excessively on scope of researchers long years. Advances a vital concern provide food with good quality growing population man. This review focuses physiology and recent advances field.
BACKGROUND The rumen harbors a complex microbial ecosystem for efficient hydrolysis of plant polysaccharides which are the main constituent of the diet. Xylanase is crucial for hemicellulose hydrolysis and plays an important role in the plant cell wall degradation. Xylanases of ruminal strains were widely studied, but few studies have focused on their diversity in rumen microenvironment. METH...
