An in vitro study was conducted using a 4 • 2 • 2 factorial design with RAC (readily available carbohydrate) levels of 30, 40, 50 and 60%, tallow levels of 0 and 3%, and urea levels of 0 and 2%. Acetic and propionic acid production and ammonia disappearance increased as the level of RAC increased from 30 to 50%. Tallow reduced acetic acid production and increased the amount of propionic acid pr...

BACKGROUND Patients with chronic kidney disease (CKD) need regular monitoring, usually by blood urea and creatinine measurements, needing venepuncture, frequent attendances and a healthcare professional, with significant inconvenience. Noninvasive monitoring will potentially simplify and improve monitoring. We tested the potential of transdermal reverse iontophoresis of urea in patients with CK...

The DOE sponsored Integrated Dry NOJSO, Emissions Control System program, which is a Clean Coal Technology Ill demonstration, is being conducted by Public Service Company of Colorado. The test site is Arapahoe Generating Station Unit 4, which is a 100 MWe, down-fired utility boiler burning a low sulfur western coal. The project goal is to demonstrate 70 percent reductions in NO, and SO, emissio...

the objective of this study was to evaluate the effects of supplementation of different level protein diets with rumen protected methionine and lysine on performance and ruminal parameters in holstein dairy cows when in their early lactation. twenty one dairy cows in their early lactations were assigned to three treatments in a randomized block design experiment of a 35-d duration period. diets...

Effects of supplemental RDP and RUP on nutrient digestion, N metabolism, urea kinetics, and muscle protein degradation were evaluated in Nellore heifers () consuming low-quality signal grass hay (5% CP and 80% NDF, DM basis). Five ruminally and abomasally cannulated Nellore heifers (248 ± 9 kg) were used in a 5 × 5 Latin square. Treatments were the control (no supplement) and RDP supplementatio...

GOLDSTEIN, LEON, AND KOY P. FORSTER. Osmoregulation and urea metabolism in the little skate Raja erinacea. Am. J. Physiol. 220(3) : 742-746. 197 1 .-Little skates, Raja erinacea, were transferred gradually (4 days) from full to approximately half-strength seawater. Steady-state conditions (with respect to solute and water balance) were established by the end of the dilution program. The skates ...
