Effects of preconditioning and extrusion of linseed on the ruminal biohydrogenation of fatty acids 1. In vivo studies [PDF]

, 2006
The extent and intermediates of ruminal biohydrogenation (BH) of fatty acids (FA) from a blend of linseed and wheat bran (70:30) were investigated in the rumen fluid, rumen particle phase and duodenal flow.

Effects of Diet Composition and Yeast Cell Wall Supplementation on Ruminal Fermentation, Gas Kinetics, Methane Production and Digestibility Assessed In Vitro Using Gas Production and DaisyII Incubator Systems

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study evaluated the effects of yeast cell wall (YCW) supplementation in diets with varying roughage‐to‐concentrate (R:C) ratios using in vitro techniques. The results demonstrated that YCW supplementation significantly reduced total gas and methane production, particularly in high‐roughage diets, without compromising dry matter digestibility or ...

Investigation of Effects of Low Ruminal pH Values on Serum Concentrations of Macrominerals, Trace Elements, and Vitamins and Oxidative Status of Dairy Cows

Ruminants
Due to the feeding system (high-concentrate diet) during the early lactation stage, ruminal pH in dairy cows follows a diurnal pattern and can remain below the critical level of 5.5 for extended periods of the day. This study aimed to evaluate the effect

In Vitro Versus in Situ Ruminal Biohydrogenation of Unsaturated Fatty Acids from a Raw or Extruded Mixture of Ground Canola Seed/Canola Meal [PDF]

, 2003
Raw or extruded blends of ground canola seeds and canola meal were used to compare in vitro and in situ lag times and rates of disappearance due to ruminal biohydrogenation of unsaturated fatty acids.

The Dairy Ruminant Gut Microbiome: Profile, Responsiveness to Seasonality and Impact on Milk Quality

Environmental Microbiology, Volume 28, Issue 5, May 2026.
The dairy ruminant gut microbiome that is shaped by host and diet is affected by seasonality and rearing. These factors can impact dairy productivity and milk quality potentially through the gut microbiota. ABSTRACT The gut microbiome (GM) and particularly the rumen microbiome (RM) affect the ruminant health and they are associated with milk quality ...

Effects of live yeast on the fatty acid biohydrogenation by ruminal bacteria [PDF]

, 2006
Addition of live yeasts in high concentrate diets for ruminants has been shown to help maintaining the ruminal pH above 6, which could enhance the microbial biohydrogenation of unsaturated dietary fatty acids.

Diet-dependent immunohistochemical evaluation of connexin 43 in the sheep rumen [PDF]

, 2016
The objective of this study was to characterize the immunohistochemical localization of plasma membrane connexin 43 in the rumen of sheep after changing the diet from hay (ad libitum) to a mixed hay/concentrate diet.

Olive Waste as Feed Supplement: Morphometrical Effects on the Ansa spiralis coli in Lambs

Anatomia, Histologia, Embryologia, Volume 55, Issue 3, May 2026.
ABSTRACT Feedlot systems for small ruminants require nutritionally adequate and viable diets, and the incorporation of olive residues can offer a sustainable and economically advantageous alternative. This study evaluated the effects of including olive waste at 7.5%, 15%, 22.5% and 30% in the diets of Texel × Ile‐de‐France lambs, assessing the ...

Maximizing efficiency of rumen microbial protein production. [PDF]

, 2015
Rumen microbes produce cellular protein inefficiently partly because they do not direct all ATP toward growth. They direct some ATP toward maintenance functions, as long-recognized, but they also direct ATP toward reserve carbohydrate synthesis and ...

Repeated Ruminal Acidosis Challenges in Lactating Dairy Cows at High and Low Risk for Developing Acidosis: Ruminal pH [PDF]

Journal of Dairy Science, 2008
The primary objective of this experiment was to determine whether lactating dairy cows that are at high (HR) or low (LR) risk for experiencing ruminal acidosis, because of their diet and stage of lactation, differ in their response to an acidosis challenge.
