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.

Effects of two enzyme feed additives on digestion and milk production in lactating Egyptian buffaloes [PDF]

, 2016
The aim of this study was to evaluate the effect of two commercial enzyme products on milk production in Egyptian buffaloes. Twenty-one lactating buffaloes (570±15 kg BW) were divided into three groups (n=7) in a randomized block design for four months ...

Performance of lactating dairy cows fed yeast and fibrolytic enzymes

Kansas Agricultural Experiment Station Research Reports, 2004
We evaluated the effect of supplementing typical dairy diets with yeast and fibrolytic enzymes on dairy cow performance. Twentyfour Holstein cows were used to evaluate the effects of yeast (Procreatin-7, a live culture of Saccharomyces cerevisiae) and various amounts of FP800 (a fibrolytic enzyme mixture) on lactation performance.

Identifying and improving the fibre-degrading activity of rumen microbe-derived fibrolytic bacteria : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Genetics at Massey University, Manawatū, New Zealand [PDF]

, 2017
The dairy industry is extremely important to the New Zealand (NZ) economy, and it accounts for approximately $16.6 billion in exports each year. In NZ, traditional feedstock for cattle, such as grass and hay, consists of cellulose-based fibrous material ...

Short‐Term Impact of Betaine Supplementation on Ruminal Microbial Relative Abundance, Nutrient Digestibility, Serum Metabolites, and Milk Composition in Heat‐Stressed Dairy Cows

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Short‐term betaine supplementation (80 g/day for 4 weeks) improved thermoregulation, ruminal fermentation, and nutrient utilisation in heat‐stressed dairy cows. These effects enhanced feed intake, milk yield, and metabolic stability by modulating rumen microbiota and reducing inflammatory and oxidative stress responses.

Effect of Diet Neutral Detergent Fibre Content on Dry Matter Intake, Nutrient Digestibility, Growth Efficiency and Carcass Characteristics of Finishing South African Mutton Merino Wether Lambs

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Feeding South African Mutton Merino lambs low‐NDF lucerne hay diets improved nutrient digestibility, energy utilisation, growth efficiency, and carcass quality. Despite lower intake at the lowest NDF level, fibre digestibility and feed conversion improved, indicating that highly digestible, low‐NDF finishing diets enhance lamb growth and carcass traits.

Effect of a Fibrolytic Enzymatic Extract from Cellulomonas flavigena on In Vitro Degradation and In Vivo Digestibility and Productive Performance of Lambs [PDF]

, 2013
An enzymatic extract from Cellulomonas flavigena was evaluated at 0, 2.5, 7.5, 12.5 mL/kg DM of total mixed ration (TMR) on the in vitro degradation of DM, NDF and ADF and in vivo at 0, 5.0 and 7.5 mL of extract per kg DM of TMR to determine the ...

Managing Primary Immunodeficiency Immunoglobulin Replacement Therapy‐Related Adverse Events With Recombinant Human C1 Esterase Inhibitor Prophylaxis: A Case Report

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Immunoglobulin replacement therapy (IRT) for primary immunodeficiency reduces infection risk and subsequent complications and can be lifesaving. However, IRT can cause severe systemic adverse events (AEs) that may limit adequate dosing. These AEs may be caused, in part, by activation and/or consumption of complement proteins, thereby lowering ...
