In vitro fermentation experiments and a feeding trial were conducted to determine how distillers byproducts impact rumen microbiology and metabolism. The in vitro rate of lactic acid disappearance was not stimulated by direct addition of distillers byproducts to mixed rumen contents collected from a steer adapted to a high concentrate diet. However, if animals were fed condensed distillers bypr...

The high energy diets that are typically fed to dairy cows can put the cow at risk of experiencing ruminal acidosis. High energy diets are low in neutral detergent fiber (NDF) and high in starch. The starch sources are often processed in a manner to optimize starch availability in the rumen and the fiber sources are often highly digestible and short in particle length. As a result, these types ...

Streptococcus bovis is a normal inhabitant of the rumen but has been implicated as a causative agent for ruminal lactic acidosis and related problems. While rarely isolated from humans, S. bovis has been identified as a causative agent for endocarditis, meningitis, and septicemia. Recent reports have also suggested a correlation between human colonic carcinoma and increased levels of S. bovis. ...

1. Whole-body intracellular pH (pHi) was measured by the 14C-labelled DMO method in twenty-four control subjects, eighteen normal subjects with induced acute metabolic alkalosis, ten normal subjects with induced acute metabolic acidosis, twelve normal subjects with chronic acidosis and in fifteen patients with chronic renal insufficiency and acidosis. 2. The change in pHi per unit change in ext...

The purpose of this study was to investigate variability among individual cows in their severity of ruminal acidosis (RA) pre- and postpartum, and determine whether this variability was related to differences in their ruminal bacterial community composition (BCC). Variability in the severity of RA among individual cows was characterized based on ruminal fermentation variables. Effects of prepar...

theaim of the current study was to assess effects of different levels of origanum vulgare (0, 250, 500, 750 and 1000 mg/l) on kinetics of gas production, some ruminal digestion and fermentation parameters, methane production and also to determine its potential in controlling rumen acidosis using in vitro method in four separate phases. in the first phase, the asymptote of gas production (a) and...

A 52 year old female patient presented to emergency casualty with Acute onset quadriparesis respiratory muscle involvement in. During initial work up Serum electrolytes showed severe hypokalemia. Arterial blood gas normal anionic gap metabolic acidosis positive urine anion and examination alkaline PH in the presence of systemic acidosis. All these findings suggest Distal Tubular Acidosis. Furth...

Two in vitro studies were carried out on nonlactating dairy cows. Experiment 1 compared the methanogenesis and rumen fermentation parameters of various microalgae (Spirulina platensis, Chlorella vulgaris, Schizochytrium spp.) protein feeds (sunflower meal, soybean alfalfa hay) with monensin (MON). Rumen determined by an gas production system. 2 ability three to prevent acidosis. They tested for...
