Factors affecting estrogen excretion in dairy heifers
… conducted to assess factors affecting estrogen excretion in dairy heifers. The objective of the first study was to quantify estrogenic activity in feces and urine during the estrous cycle. Ten non-pregnant Holstein heifers were fed the same diet for 28 d. Plasma, feces, and urine samples were …

Urinary Excretion of (1-3)-Beta-D-Glucans.
… the present studies investigated the renal excretion of (1→3)-β-D-glucans following intravenous and oral administration. Three fluorescently-labeled glucans were administered to adult male rats in the presence or absence of toxic challenge. Urine specimens were collected and analyzed by …

Excretion of Antibiotic Resistance Genes by Dairy Calves
Twenty-eight Holstein and crossbred calves of both genders were used to evaluate the effect of milk replacer antibiotics on abundance of selected antibiotic resistance genes (ARG) in the feces. Calves were blocked by breed, gender, and birth order, and assigned to one of three treatments at birth. …

Studies on the metabolism and excretion of chlorine chloride
… A study of the rate of trimethylamine excretion in the rabbit following oral administration of choline chloride.</p><p>2. A study of the rate of trimethylamine formation while incubating choline chloride with the intestinal contents of rabbits, in an attempt to correlate the rate of …

Starch Digestion and Phosphorus Excretion in Lactating Dairy Cows
… period, while rumen fluid was sampled on d 18. Excretion of feces, urine, P, and N was lower in cows fed SF than in cows fed DG. Milk yield was unaffected by diet despite a lower DMI by cows fed SF. Cows fed SF tended to have a higher feed efficiency and lower milk urea nitrogen (MUN) …

Technologies to Reduce Nutrient Excretion and Odor Production in Swine
… Reducing CP decreased (P < 0.001) urinary N excretion by 56% and total N excretion by 41%. Overall, for every one percentage unit reduction in dietary CP (combined with AA supplementation) there were reductions in total N losses (fecal plus urinary) by 8%, and ammonia production by 15%, but …

The excretion of calcium and phosphorus by the human kidney
In this thesis I have attempted to assemble in some coherent form the fruits of two years' research into the renal handling of calcium and phosphorus.

Manure and Nutrient Accretion, Partitioning, and Excretion in Holstein Heifers
… nutrient utilization, partitioning, and excretion are scarce and are becoming necessary. That combined with the fact that feeding programs for heifers are highly variable from region to region and even from farm to farm indicated the need to examine the effects of diet on nutrient …

The urinary excretion of sulfoconjugates in an adult male population
… difference was observed only for sulfate excretion in relation to beer consumption. Beer consumers excreted more total sulfate in both one-day and three-day samples, and more bound sulfate in the three-day sample than non-beer consumers. Analysis of the three-day data revealed intra- …

Urinary excretion of trace metals in the streptozotocin-diabetic rat
… is responsible for increased urinary trace metal excretion was examined in normal and streptozotocin-diabetic rats. Induction of the diabetic condition resulted in a rapid and persistent increase in the quantities of zinc, copper and iron lost in the urine daily. Diabetic rats excreted 3.4, 5.0, …

The effects of broccoli on the excretion of urinary conjugates
… Dietary broccoli increased the urinary excretion of mercapturates and sulfoconjugates, but did not influence the excretion of glucuronides and amino acid conjugates. A significant linear trend was observed over the six-day broccoli diet treatment for both urinary mercapturate (P<0.005) …

Sleep disorders and melatonin secretion-excretion patterns in children with epilepsy /
… group. The diurnal profiles of MLT secretion and excretion showed high inter-individual variability in both study groups. The circadian rhythms of salivary MLT secretion and excretion of metabolite 6-sulphatoxymelatonin (aMT6s), core body temperature, pulse, blood pressure were preserved in …

Effect of Almond Intake on Fecal Fat Excretion in Healthy Adults
… reflects the fatty acid composition of almonds. Excretion of fat, particularly from almonds, may explain why weight balance is achieved with daily consumption of ~68 g of almonds.</p>

Absorption, Distribution and Excretion of Oxytetracycline and Tetracycline in Female Beagles
The absorption, distribution and excretion of oxytetracycline and tetracycline were studied in female beagles following intra-arterial and oral drug administration. Concentrations of drug in body fluids and selected tissues were determined by high performance liquid chromatography utilizing an …
