hydrochlorothiazide (hct) is a diuretic agent which is shown to be effective in the treatment of hypertension. literature reports have demonstrated that urinary excretion data may be used to assess the bioavailability of various formulations containing this thiazide. also hct consumption by the athletes is one of the drugs which should be regulated by world anti-doping agency (wada), because of...

The origin of D-lactate, the most important acid contributing to metabolic acidosis in the diarrheic calf, is unknown. We hypothesized that because D-lactate is produced only by microbes, gastrointestinal fermentation is the source. The objective of this study was to determine whether D-lactate production occurs in the rumen, colon, or both, and to measure D- and L-lactate concentrations in uri...

in this study, we determined the effects of replacing different levels of alfalfa with pistachio hull (ph) on feed intake, digestibility of nutrients, rumen fermentative parameters, blood metabolites and nitrogen metabolism in balochi male lambs. three male lambs (35±2 kg live weight) equipped with ruminal and abomasual cannulas were randomly assigned into a 3 × 3 latin square design. experimen...

Two trials were conducted to study ruminal lactic acid, histamine, tyramine and tryptamine concentrations following glucose engorgement in vitro and in vivo. Also, electrolyte changes in rumen fluid, blood plasma and urine during lactic acidosis were examined. Experiment 1 involved the addition of glucose to rumen fluid in vitro. After 30 hr of incubation, decreases in pH and increases in lacti...

Microbial protein synthesis of steers (liveweight 286±9 kg) was compared with diets of ad libitum winter grass and fodder beet with 1 kg DM of lucerne silage. The experimental design was a four-by-two treatment comparison (experiment 1 and 2), using 11 day individual pen trials with total faecal and urinary collection. The trials assessed in vivo digestibility of diets, and diurnal variations i...

1. The effects of four diets on water intake, rumen fluid outflow-rate, rumen pH and mineral metabolism were studied in wether sheep. The diets were barley and hay, flaked maize and hay, dried grass and frozen grass. 2. Experimental periods were of 12 d duration, and plasma magnesium concentrations were lower at the end of treatment periods when the grass diets were given and were significantly...

We hypothesize that soybean hulls (SH) and dried distillers grains with solubles (DDGS) can be used in lamb diets to increase dietary energy density compared with a traditional grass hay (GH) and soybean meal (SBM) diet without causing adverse effects on nutrient digestibility and rumen function. To test this hypothesis, four ruminally-cannulated wethers were used in a 4x4 Latin square design t...

bacteria make up about half of the living organisms inside of the rumen. however, they do more than half of the work in the rumen. the bacteria work together. some breakdown certain carbohydrates and proteins which are then used by others. some require certain growth factors, such as b-vitamins, which are made by others. some bacteria help to clean up the rumen of others’ end products, such as ...

The aim of this study was to investigate the variations of vitamin B12 and homocysteine in blood of dairy cows during subacute ruminal acidosis (SARA). On 228 subjects ruminal liquid was collected through rumenocentesis technique and rumen pH was immediately measured by a portable pH-meter. On the basis of pH values all cows were classified (bovine class) in Group A (animals with rumen pH>5.7),...
