The occurrence of bacteriophages in the rumen and their influence on rumen bacterial populations
Experientia, 1974Se han demostrado que dos cultivos de bacterias de rumen (un baston gram negativo, designado W461, y una cepa de ovalos deEadie) estan infectados con bacteriofagos. El bacteriofago de W461 es templado; aquel de los ovalos es virulento y depleta rapidamente la poblacion bacteriana en vivo.

AbstractSoluble lipases obtained from the rumen contents of pasture‐fed cows had pH optima of 7.0 and 8.0 to 8.5, respectively, with tributyrin and triolein as substrates. At these optima the activity towards tributyrin was about 30 times greater than towards triolein.Tributyrin‐splitting bacteria were abundant in the rumen of pasture‐fed cows but none

Progress in Lipid Research, 1978
Ruminants supply humans with a readily available source of fat in the form of both tissue and milk lipids. It has been known for over 50 years that the compositions of ruminant tissue and milk lipids differ markedly from those of non-ruminant herbivores (Banks and Hilditch, 1931), and much research has been done on ruminant lipids and on the microbial ...

Improving microbial degradation of plant cell wall polysaccharides remains one of the highest priority goals for all livestock enterprises, including the cattle herds and draught animals of developing countries. The North American Consortium for Genomics of Fibrolytic Ruminal Bacteria was created to promote the sequencing and comparative analysis of ...

Veterinary Record, 1983
The regulation of rumen fermentation and motility are described to provide a framework within which the opportunities and problems of intensified ruminant nutrition can be considered. The ruminant animal maintains favourable conditions for microbial growth in its rumen and in turn is nourished by the products of fermentation.

Control of rumen methanogenesis
Environmental Monitoring and Assessment, 1996During the last decades, considerable research on methane production in the rumen and its inhibition has been carried out. Initially, as methane production represents a significant loss of gross energy in the feed (2-15%), the ultimate goal of such intervention in rumen fermentation was an increase in feed efficiency. A second reason favouring research

Rumen Function and Development
Veterinary Clinics of North America: Food Animal Practice, 2017The ruminal epithelium is a complex tissue that serves as an important protective barrier as well as a metabolically important tissue for whole-animal energy metabolism. Up to 70% of the energetic needs of mature animals are absorbed as short-chain fatty acids through the stratified squamous epithelium, and it serves as the primary producer of ketones ...

Veterinary Microbiology, 1985
Out of a sample of 200 rumens from sheep slaughtered in Edinburgh, papillomas were found in 25. They occurred as fibro-papillomas, mostly along the pillar of muscle between the dorsal and ventral rumen, and were often multiple. No inclusion bodies were seen in the lesions or papilloma virus particles on electron microscopy.

Manipulation of fermentation in the rumen
Journal of the Science of Food and Agriculture, 1976AbstractArtificial saliva (4 litres/day) was infused into the rumen of sheep fed a semi‐purified diet at hourly intervals. Dilution rate and the efficiency of synthesis of microbial protein in vivo were increased. The pattern of rumen fermentation was altered; the molar proportion of propionic acid decreased (32–20%) and acetic acid increased (58–66 ...

Fermentation in the Rumen of the Sheep
Nature, 1950ABSTRACT A previous communication in this series of papers (Gray, Pilgrim & Weller, 1951) gave an account of the fermentation of wheaten hay and lucerne hay by organisms from the rumen of the sheep, in which the overall production of each of the main volatile fatty acids was determined.
