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

Vet Med Sci
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.

Effects of Replacing Dry-rolled Corn with Increasing Levels of Corn Dried Distillers Grains with Solubles on Characteristics of Digestion, Microbial Protein Synthesis and Digestible Energy of Diet in Hair Lambs Fed High-concentrate Diets. [PDF]

, 2013
Four male lambs (Katahdin; average live weight 25.9±2.9 kg) with "T" type cannulas in the rumen and proximal duodenum were used in a 4×4 Latin square experiment to evaluate the influence of supplemental dry distillers grain with solubles (DDGS) levels (0,

Características ruminais e eficiência de síntese microbiana em novilhos alimentados com cama de frango e suplemento à base de microbiota ruminal liofilizada Ruminal characteristics and microbial synthesis in steers fed broiler litter and supplement based on lyophilized ruminal microbiota

Revista Brasileira de Zootecnia, 1999
O experimento foi realizado para avaliar o efeito de dois níveis de cama de frango (15,0 e 30,0%), associada ou não a um suplemento à base de microbiota ruminal liofilizada de bovinos adultos (0 e 10 g/anim.dia), na alimentação de novilhos Holandês/Zebu.

Intracellular pH of acid-tolerant ruminal bacteria [PDF]

Applied and Environmental Microbiology, 1991
Acid-tolerant ruminal bacteria (Bacteroides ruminicola B1(4), Selenomonas ruminantium HD4, Streptococcus bovis JB1, Megasphaera elsdenii B159, and strain F) allowed their intracellular pH to decline as a function of extracellular pH and did not generate a large pH gradient across the cell membrane until the extracellular pH was low (less than 5.2 ...

Níveis de uréia na ração de novilhos de quatro grupos genéticos: parâmetros ruminais, uréia plasmática e excreções de uréia e creatinina Urea levels in diet for steers of four genetic groups: ruminal parameters, plasma urea, urea and creatinine excretions

Revista Brasileira de Zootecnia, 2008
Objetivou-se avaliar o efeito de quatro níveis de uréia na ração (0; 0,65; 1,3 e 1,95% na matéria seca - MS) sobre pH e amônia ruminais, concentração plasmática de uréia, excreção fracional de uréia e excreções de uréia e creatinina, bem como avaliar as ...

In vitro study of dietary factors affecting the biohydrogenation shift from trans-11 to trans-10 fatty acids in the rumen of dairy cows [PDF]

, 2012
On the basis of the isomer-specific effects of trans fatty acids (FA) on human health, and the detrimental effect of t10,c12-conjugated linoleic acid (CLA) on cows’ milk fat production, there is a need to identify factors that affect the shift from trans-

Niacin alters the ruminal microbial composition of cattle under high-concentrate condition

Animal Nutrition, 2017
To understand the effects of niacin on the ruminal microbial ecology of cattle under high-concentrate diet condition, Illumina MiSeq sequencing technology was used. Three cattle with rumen cannula were used in a 3 × 3 Latin-square design trial.
