Lipid microspheres containing urea for slow release of non-protein N in ruminant diets
(2022-01-01)
Context: Urea is widely used in ruminant diets as a source of non-protein nitrogen (NPN), partially substituting for true protein in feed, but high levels of urea in the diet may cause toxicity. Aims: This study investigated ...
Can Micronized Sulfur in Urea Reduce Ammoniacal Nitrogen Volatilization and Improve Maize Grain Yield?
(2019-01-01)
Micronized sulfur (S) in urea may reduce nitrogen (N) loss by ammoniacal N (NH3–N) volatilization and provide a better use for S from oil refineries, thereby improving plant nutrition by providing N and S. The objective ...

Evaluation of chronic peritoneal dialysis using urea kinetic modelling Evaluación de la diálisis peritoneal crónica mediante el modelo de cinética de urea
(2004)
Curently, urea kinetic modeling is routinely accepted to evaluate peritoneal dialysis (PD) through the calculation of Kt/V (normalized whole body urea clearence) and nPNA (normalized protein equivalent of total nitrogen ...
Carnauba wax as a wall material for urea microencapsulation
(Wiley-Blackwell, 2019-02-01)
BACKGROUND The high ureolytic activity of rumen microbiota is a concern when urea is used in ruminant feed, because it leads to fast urea conversion, resulting in possible intoxication and lower nitrogen utilization. This ...
Green Determination of Urea in Moisturizers by Diffuse Reflectance Spectroscopy
(2017-08-13)
This manuscript describes the development and application of a simple, inexpensive, and green method for the quantification of urea in skin moisturizer creams, using a combined spot test/diffuse reflectance spectroscopy ...
Effects of dietary urea levels on milk protein fractions of Holstein cows
(ELSEVIER SCIENCE BV, 2008)
The aim of this study was to evaluate the effects of substituting soybean meal for urea on milk protein fractions (casein, whey protein and non-protein nitrogen) of dairy cows in three dietary levels. Nine mid-lactation ...
