Journal ArticleDOI
Lipid metabolism in the rumen.
TL;DR: The mechanism of how lipids interfere with ruminal fermentation is a complex model involving partitioning of lipid into the microbial cell membrane, potency of the lipid to disrupt membrane and cellular function, physical attachment of microbial cells to plant surfaces, and expression and activity of microbial hydrolytic enzymes.
Book ChapterDOI
Manipulation of ruminal fermentation
TL;DR: A proper balance between fermentative and glandular digestion needs to be achieved for optimal productivity in ruminants as mentioned in this paper, which is the goal of most of the diets formulated with an intention of providing the animal with optimal levels of nutrients to achieve the optimal level of performance.
Journal ArticleDOI
Rumen fermentation in vitro as influenced by long chain fatty acids.
TL;DR: Responses of ruminal microbes to long-chain fatty acids in forms of free acids, calcium salts, or triglycerides were measured in trials with rumen cannulated heifers to confirm that these are efficacious for protectingRuminal microbes from adverse effects of fat.
Journal ArticleDOI
Effect of Fatty Acids or Calcium Soaps on Rumen and Total Nutrient Digestibility of Dairy Rations
T.C. Jenkins,D.L. Palmquist +1 more
TL;DR: Two trials ascertained whether feeding fatty acids as preformed calcium soaps would permit normal digestibility of fiber without reducing availabilities of fatty acids or energy and found that tallow fatty acids markedly reduced Digestibility of dry matter and fiber in the rumen.
Journal ArticleDOI
Ruminal synthesis, biohydrogenation, and digestibility of fatty acids by dairy cows
TL;DR: Ruminal synthesis and biohydrogenation of fatty acids in dairy cows were determined by sampling duodenal digesta through T-cannulas and fatty acids synthesized in greatest amounts were odd or branched chains.

Journal ArticleDOI
Lipid metabolism in the rumen
TL;DR: Much research has been done on ruminant lipids and on the microbial transformations in the rumen which are responsible for the distinctive lipid composition, and factors regulating lipid metabolism.
Journal ArticleDOI
Antibacterial Activity of Long Chain Fatty Acids and the Reversal with Calcium, Magnesium, Ergocalciferol and Cholesterol
TL;DR: Screening tests indicated that Gram positive bacteria are inhibited by long chain fatty acids, and no inhibition was demonstrated with Gram negative bacteria.
Journal ArticleDOI
The effects of fatty acids on pure cultures of rumen bacteria
TL;DR: The effects of fatty acids, at low concentrations (0-005-O5 g/1), on the growth of seven species of rumen bacteria were examined in this paper, and the results are consistent with the reported effects of lipids on rumen function.
Journal ArticleDOI
Effect of Long Chain Fatty Acids on Bacterial Respiration and Amino Acid Uptake
H. Galbraith,T. B. Miller +1 more
TL;DR: Long chain fatty acids stimulated oxygen uptake by Gram positive bacteria at bactericidal and protoplast lytic concentrations and produced inhibition at higher levels and the susceptibility of organisms to inhibition was of the same order as the sensitivity to other antibacterial effects.
