REISER,1, and more recently Shorland et al. 2, reported experiments in which rumen contents of sheep were incubated in vitro with linseed oil and with oleic, linoleic and linolenic acids. These experiments, and others using the living animal3–5, demonstrated that hydrogenation of double bonds of unsaturated fatty acids occurred and that this was ...

The cow is a ruminant, and cow's milk has evolved to promote bacterial growth in the upper small bowel; whereas human milk has evolved to discourage bacterial growth. Examination of the constituents of the two milks shows that their differences can be accounted for in terms of this difference in function.

The aim of this invited mini-review is to summarize the rumen transfaunation literature. Rumen transfaunation using the cud from a healthy donor animal to treat a sick recipient animal was practiced long before our understanding of rumen microorganisms.

Journal of the Science of Food and Agriculture, 1974
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

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.

Comparative Study of the Urease in the Rumen Wall and Rumen Content
Nature, 1966IN the course of the ruminohepatic nitrogen cycle1,2, or by supplementation in feeding3, a considerable amount of urea can enter the rumen. The ureolytic activity of the rumen content was investigated and found to be due to some species of ruminal micro-organisms.

Rumen Overload and Rumenitis in White-Tailed Deer
The Journal of Wildlife Management, 1975Rumenitis was diagnosed on the basis of histopathology in 30 of 108 white-tailed deer (Odocoileus virginianus) found dead during a severe winter in Saskatchewan. Rumenitis or rumen over- load was considered to be the cause of death of 5 of these deer, and to have contributed to the death of 4 others (8.3 percent of the deer examined).

This chapter deals with the effects of dietary changes on the fermentation processes in the rumen and their consequences for the amount and type of nutrients delivered to the ruminant host, as well as the mathematical description of these processes. In addition to the fermentation in the lumen, the tissues in the rumen wall are also of importance for ...

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

Effect of defaunating the rumen
Animal Feed Science and Technology, 1988Abstract The effects of defaunation have been extensively studied during the last 10 years. Results in the literature suggest that elimination of protozoa greatly modified the microbial environment of the rumen. In consequence, defaunation influences the intensity of fermentation and its qualitative evolution.
