Effects of Selenium Supplementation on Rumen Microbiota, Rumen Fermentation, and Apparent Nutrient Digestibility of Ruminant Animals: A Review

, 2021
Enzymes excreted by rumen microbiome facilitate the conversion of ingested plant materials into major nutrients (e.g., volatile fatty acids (VFA) and microbial proteins) required for animal growth. Diet, animal age, and health affect the structure of the

Research progress on effect of dietary concentrate to coarse ratio on performance of ruminants

Siliao yanjiu, 2023
The ratio of dietary concentrate to coarse is an important factor affecting the performance of ruminants. An appropriate ratio of dietary concentrate to coarse can maintain rumen fermentation function of ruminants, stabilize rumen environment, prevent ...

Evaluating the In Vitro Digestibility of Black Soldier Fly (Hermetia illucens L.) Larvae as Potential Feed Ingredient in Dairy Cattle Silage‐Based Diets: A Focus on Proteins

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Dietary protein has a substantial economic impact on cattle feed, and it is also a critical component for animal growth and productivity. Several environmental issues related to soybeans have led to an increased interest in novel protein sources, such as insects.

Effect of Alkaline Mineral Complex Buffer Supplementation on Milk Performance, Serum Variables, Rumen Fermentation and Rumen Microbiota of Transition Dairy Cows

, 2023
The present study investigates the effect of 50 mL AMCB taken daily as a dietary supplement on the rumen fermentation, microbiota, and production performance of 40 Holstein dairy cows in the transition period with 2.76 ± 0.48 parity and 650 ...

Studies on the rumen fermentation by using an artificial rumen technique

Nihon Chikusan Gakkaiho, 1969
第1胃内におけるVFA生成に及ぼす基質の影響について検討する目的で,in vitroの人工ルーメン法により一連の実験を実施した.実験1:各種単一基質からのVFA生成.セルロース,イネワラ,オーチャードグラス乾草,エンバク,トウモロコシ,および澱粉を基質として供試し2段階の基質濃度(5gおよび30g/300ml)で試験を行なった.VFA産生量は,基質濃度を増加することにより2倍(セルロース)から4倍(トウモロコシ)と増大したが,澱粉のみは僅かながら減少した.VFAのモル比では,プロピオン酸に対する醋酸の比率が,澱粉質基質において低く,セルロースをのぞく繊維質基質では高かった.セルロースでは,この比率が最も低い値を示した.基質濃度を変えることによって,VFAモル比にっいても変動が認められた.実験2 ...

16S rRNA gene sequencing and non-targeted metabolomics analysis of the effects of different milk volumes on rumen fermentation parameters, rumen microbiota, and rumen metabolites in calves

Frontiers in Animal Science
IntroductionThe health of calves depends on the colonization of rumen microorganisms in the early stages of growth and development. This study explored the effects of different milk volumes on rumen fermentation parameters, rumen microbiota, and rumen ...

Associations Between Benzoxazinoids, Plant Development and Nutritional Parameters in Different Maize Maturing Genotypes

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Maize (Zea mays L.) silage is a major energy source in ruminant diets and provides fermentable substrate for the rumen microbiota. In addition, forage maize contains benzoxazinoids (BXs), defence‐related secondary metabolites with antimicrobial activity that remain detectable after ensiling.

Expression of Mineral and Urea Transport‐Related Genes in the Salivary Glands and Ruminal Epithelium of Young Goats Fed Nitrogen‐ and/or Calcium‐Reduced Diets

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT An adequate supply of protein and minerals, particularly nitrogen (N) and calcium (Ca), is essential for ruminant growth and metabolic function. The rumen and salivary glands are crucial for nutrient and electrolyte homoeostasis via specialised transport proteins.

Poetic Sociology

Sociological Forum, EarlyView.
ABSTRACT Can sociologists feel? Sociological writing can be beautiful, making us think differently about people, processes, and structures. Yet traditional academic writing that does this is rare. For example, most articles adhere to a jargon‐filled format and structure that mimics a detached and disciplined writer.
