Effects of degradable protein and non-fibre carbohydrates on microbial growth and fermentation in the rumen simulating fermenter (Rusitec)

Italian Journal of Animal Science, 2015
A rumen simulation technique (Rusitec) apparatus with eight 800 ml fermentation vessels was used to investigate the effects of rumen degradable protein (RDP) level and non-fibre carbohydrate (NFC) type on ruminal fermentation, microbial growth, and ...

Effect of protein supplementation on ruminal parameters and microbial community fingerprint of Nellore steers fed tropical forages

Animal, 2016
In tropical regions, protein supplementation is a common practice in dairy and beef farming. However, the effect of highly degradable protein in ruminal fermentation and microbial community composition has not yet been investigated in a systematic manner.

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

Multi‐omics reveals gastrointestinal metabolic disorder‐induced diarrhea in postpartum dairy cows

iMetaOmics, EarlyView.
Nutritional diarrhea is a pervasive, costly challenge in dairy production. Using integrated metagenomic and metabolomic profiling, we identified coordinated microbial and metabolic alterations across the rumen, hindgut, and serum. In the rumen, enrichment of Prevotella sp.

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 ...

Copaiba oleoresin as a substitute for sodium lasalocid in high‐concentrate diets for lambs: growth performance, ingestive behavior, and metabolic and ruminal parameters

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The indiscriminate and excessive use of ionophore additives has been associated with the emergence of multi‐resistant pathogenic strains and the global spread of antibiotic resistance, raising serious public health concerns. Thus, plant biocompounds have been the focus of several studies aiming to replace ionophore additives in ...
