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

open access: yesVeterinary 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 ...

Are Insects a Feasible Option or Just a Hyped Promise in Ruminant Nutrition? A Systematic Review of What Has Been Done and What Lies Ahead

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Insects are emerging as sustainable alternatives for ruminants. This systematic review evaluates in vitro and in vivo evidence on insect‐based feeds in ruminant nutrition, discussing their outcomes and elucidating underlying mechanisms. Despite promising effects on rumen fermentation, growth, and product quality, inconsistencies related to insect ...

Effects of Beet‐Vinasse (Condensed Molasses Soluble) Addition on the Performance, Milk Fatty Acid Profile, Digestibility, Blood Parameters, and Ruminal Fermentation of Early Lactating Holstein Cows

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Vinasse supplementation at 1.5%–3% enhances nutrient digestibility, ruminal fermentation and production efficiency in early‐lactating Holstein cows. However, without rumen microbial or immune response data, long‐term safety and efficacy require further study.
