Therapeutic efficacy of certain poly herbal formulations and probiotics along with heterologous cud transplantation was evaluated in simple indigestion in buffaloes. A total of 18 buffaloes suffering from simple indigestion were treated with Suruchi bolus (10 g twice daily) or Gastricare powder (15g twice daily) or Yeasacc bolus with heterologous cud from healthy sheep. Clinical examination and...

The hydrolysis of ochratoxin A (OA) and the corresponding formation of its hydrolysis product, alpha ochratoxin (O alpha), by ruminal digesta and in the rumen of hay-fed and grain-fed sheep were compared. Ruminal contents from sheep fed diets with hay or with grain hydrolyzed OA in vitro; the majority of the activity was associated with the particulate fraction of the ruminal contents. The rate...

1. A low-magnesium diet was fed to four sheep, each of which had been surgically prepared with a rumen fistula, a tube into the cranial one-third of the omasum, a tube to the cranial one-third of the abomasum and a re-entrant duodenal cannula. Mg, as gluconate or acate or acetate, was continuously infused for 12-14 d in turn into (1) the caudal duodenal cannula, (2) the abomasum, (3) the omasum...

This paper describes the development of a microbial fuel cell (MFC) for electricity production from cellulose that is based on mixed culture of rumen bacteria in vitro. The fibrolytic bacteria isolated from rumen fluid were used in anode compartment of MFC, which can release glucose up to 15 g/L from carboxymethyl cellulose (CMC). At the same time, the maximum power density of 100.60mWm was gen...

Globally methane (CH4) emissions from ruminant livestock account for 29% of total CH4 emissions. Inherited variation about CH4 emissions of different animal species might provide new opportunity for manipulating CH4 production. Six rumen-simulating fermenters (Rusitec) were set up for this study lasting for 16 d. The diet consisted of forage to concentrate ratio of 50:50 with barley straw as th...

Aims The aim of this study was to isolate and identify a cellulolytic bacterium from the rumen fluid of Aceh's cattle. Biodegradation by cellulolytic rumen bacteria can be used as a source of cellulolytic bacteria that act to degrade feed fibrous material so as to improve the quality of nutrients and digestibility of feed ingredients at a cheaper price than the use of commercial cellulase enzym...

Microorganims of the bovine rumen fluid biocatalyzed the reduction of nitro-compound substrates to yield the respective amines. This enzymatic process, using ruminal contents, has rarely been reported in association with the bioreduction of nitro groups. The biotransformation reactions catalyzed by this system were dependent of both the electronic characteristics and the area/volume of the nitr...

Anaerobic fungi inhabit the rumen and actively degrade plant cell walls. Rumen fungi produce high levels of cellulases and hemicellulases and are particularly proficient in producing xylanases. These enzymes are regulated by substrate (especially soluble sugars) available to the organisms. Fungi degrade unlignified (i.e., no histochemical reaction for phenolics) plant walls totally, indicating ...

Insecticides containing organophosphate, chlorinated hydrocarbon, and carbamate were tested with bovine ruminal ingesta fractions. Rumen bacteria exposed to insecticide levels of 0 to 500 ppm in rumen fluid for 4 hr were inoculated into rumen fluid-starch feed extract medium. No apparent significant bacterial count inhibitions were noted. Also, when insecticides were used as carbon sources at c...
