TLDR
A large population of ciliates was associated with increases in both rumen ammonia and plasma urea but had a stabilizing effect on ruminal pH, and effects of ciliate protozoa are related to animal performance.About:

Factors Affecting the Utilization of ‘Poor-Quality’ Forages by Ruminants Particularly Under Tropical Conditions
TL;DR: The ratio of sugars and starches to fibre in a diet and the timing of urea supplements and the ratio of glucose to starch in a Diet are compared.

Saponin rich tropical fruits affect fermentation and methanogenesis in faunated and defaunated rumen fluid
H.D. Hess,Michael Kreuzer,T.E. Díaz,Carlos E. Lascano,Juan E Carulla,C.R. Soliva,A. Machmüller +6 more
TL;DR: This study demonstrated that supplementation with S. saponaria is effective against ruminal methanogenesis, but that this was not exclusively an effect of the associated depression in protozoal count.

Effects of bacterial direct-fed microbials on ruminal fermentation, blood variables, and the microbial populations of feedlot cattle
TL;DR: Although blood pH and blood glucose were not affected by DFM supplementation, steers fed PE had numerically lower concentrations of blood CO2 than control steers, which is consistent with a reduced risk of metabolic acidosis.
Journal ArticleDOI
The effect and mode of action of saponins on the microbial populations and fermentation in the rumen and ruminant production.
TL;DR: There is need for systematic research based on chemical structures of saponins, nutrient composition of diets and their effects on rumen microbial ecosystem to obtain consistent results.
Journal ArticleDOI
Effects of alfalfa extract, anise, capsicum, and a mixture of cinnamaldehyde and eugenol on ruminal fermentation and protein degradation in beef heifers fed a high-concentrate diet
TL;DR: The results indicate that at the doses used a mixture of cinnamaldehyde and eugenol, anise oil, and capsicum oil may be useful as modifiers of ruminal microbial fermentation in beef production systems.

Effect of ammonia concentration on rumen microbial protein production in vitro
L. D Satter,L. L Slyter +1 more
TL;DR: The results suggest that addition of non-protein N supplements to ruminant rations are warranted only if the prevailing concentration of ruminal ammonia is less than 50 mg NH3-N/l ruminal fluid.

Enzyme method for determination of α-linked glucose polymers in biological materials
J. C. MacRae,D. G. Armstrong +1 more
TL;DR: In this article, a method was devised in which the specific hydrolysis of starch completely to glucose is achieved by means of an amyloglucosidase, and the contents of α-linked glucose polymers in a number of biological samples were determined.
