Influence of fibrolytic enzymes on ruminal disappearance and fermentation in steers fed diets with short and long particle length of forage

Italian Journal of Animal Science, 2010
The effects of an exogenous fibrolytic enzyme mixture on in sacco ruminal disappearance and fermentation of growing (380 kg body weight) and finishing (440 kg body weight) steers fed with diets to short (10 mm) and long (50 mm) particle length (PL) were ...

Limits of Exogenous Fibrolytic Enzymes to Improve Digestion and Intake of a Tropical Grass

Asian-Australasian Journal of Animal Sciences, 2007
The effect of the addition of exogenous fibrolytic enzymes (mainly xylanase and cellulase activities, 15 ml/15 kg of fresh forage), on intake, total tract digestibility and nylon bag degradability of a chopped fresh Digitaria decumbens grass was studied at 2 stages of regrowth ( 21 and 56-day old grasses).

Use of natural ensiling additives with tropical grasses: Physicochemical properties, in vitro fermentation characteristics, and microbial community diversity indices

JSFA reports, EarlyView.
Abstract Background Improving feed quality, availability, and cost‐effectiveness is a big challenge for livestock to ensure animal‐derived food for nutritional security. The aim of the study was to find out how some natural ensiling additives affect physicochemical properties, proximate composition, microbial population, in vitro fermentation ...

Effects of a combination of fibrolytic and amylolytic enzymes on ruminal enzyme activities, bacterial diversity, blood profile and milk production in dairy cows

Animal, 2022
We hypothesised that adding a combination of fibrolytic and amylolytic enzymes to the diet of early-lactation dairy cows would improve rumen enzyme activity and bacterial diversity, promote energy metabolism, and benefit milk production in cows.

Effect of Direct-Fed Fibrolytic Enzymes on the Lactational Performance of Dairy Cows

Journal of Dairy Science, 1999
In trial 1, 30 midlactation (213 d in milk) Holstein cows were randomly assigned to a control or enzyme treatment in a two-period crossover design and were fed a total mixed ration based on alfalfa hay and silage. Cows on the enzyme treatment received an enzyme solution containing cellulases and xylanases, which was sprayed on the forage component of ...

A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

Advanced Science, Volume 13, Issue 51, 14 September 2026.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...

Effect of Pre-Treating Dietary Moringa oleifera Leaf Powder with Fibrolytic Enzymes on Physiological and Meat Quality Parameters in Jumbo Quail

, 2022
High fiber levels (165 g neutral detergent fibre (NDF)/kg DM) in Moringa oleifera leaf powder (MOLP) could limit its utilization as a nutraceutical source in Jumbo quail diets.

Nutritive Value and Nutrient Digestibility of Silages From Different Parts of Fodder Beet With or Without Lactobacillus buchneri Inoculants for Sheep

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
Whole fodder beet silage (with/without Lactobacillus buchneri) in sheep diets improved dry matter intake and rumen fermentation compared to tops or bulbs alone. Although corn silage showed highest digestibility, whole beet silage—especially with LB—demonstrated promising rumen pH, NH3‐N and acetate:propionate ratio, serving as a viable alternative feed.

Effects of Perovskia abrotanoides Kar. Essential Oil on Greenhouse Gas Mitigation and Energy Efficiency Improvement in Sheep Rumen: An In Vitro Study

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
The essential oil of Perovskia abrotanoides Kar. (rich in 1,8‐cineole and camphor) linearly reduced methane production (up to 57.5%) and total protozoa population in sheep rumen fluid in vitro. Simultaneously, it increased microbial biomass production, microbial synthesis efficiency and the partitioning factor, indicating improved rumen energy ...
