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,

The effect of pH on ruminal methanogenesis [PDF]

FEMS Microbiology Ecology, 1996
When a fistulated cow was fed an all forage diet, ruminal pH remained more or less constant (6.7 to 6.9). The ruminal pH of a concentrate-fed cow decreased dramatically in the period soon after feeding, and the pH was as low as 5.45. Mixed ruminal bacteria from the forage-fed cow converted CO2 and H2 to methane, but the ruminal fluid from the ...

Factors associated with ruminal pH at herd level [PDF]

Journal of Dairy Science, 2012
The objective of this study was to evaluate factors associated with ruminal pH at herd level. Four hundred and thirty-two cows of a Thuringian dairy herd were sampled before claw trimming using a rumen fluid scoop. Volume and pH of the rumen sample were measured, and lactation number, percentage of concentrates in the ration, days in milk (DIM), time ...

Dietary molasses increases ruminal pH and enhances ruminal biohydrogenation during milk fat depression [PDF]

Journal of Dairy Science, 2011
Feeding high-concentrate diets has the potential to cause milk fat depression, but several studies have suggested that dietary sugar can increase milk fat yield. Two experiments were conducted to evaluate the ability of dietary molasses to prevent milk fat depression in the presence of a 65% concentrate diet. In trial 1, molasses replaced corn grain at

Concentration of 2,3 bisphosphoglycerate in cattle affected with acute ruminal acidosis

Veterinary Medicine and Science, 2021
The main objective of the study conducted here was to estimate the concentration of 2,3‐Bisphosphoglycerate (2,3‐BPG), 1,3‐Bisphosphoglycerate (1,3‐BPG), bisphospho‐glycerate mutase (BPGM) and 3‐phosphoglycerate (3PG) in cattle clinically diagnosed with ...

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 rumen simulations show a reduced disappearance of deoxynivalenol, nivalenol and enniatin B at conditions of rumen acidosis and lower microbial activity [PDF]

, 2020
Ruminants are generally considered to be less susceptible to the effects of mycotoxins than monogastric animals as the rumen microbiota are capable of detoxifying some of these toxins.
