2023年3月8日 The body excretes blood urea in urine and milk. Urea nitrogen (N) levels in blood plasma, blood serum and milk of an individual cow are highly related. Therefore,
2021年3月8日 Urea is abundant in human milk, representing a large part of the non-protein nitrogen (NPN). We found that B. longum subsp. infantis (ATCC17930) can use urea as
13C/15N Colorado Plateau Stable Isotope Laboratory Isotope Friscic Group Projects. Grinding can be achieved via a mortar and pestle a ball mill grinder a mixer mill etc The
2021年5月12日 The normal range of urea nitrogen in blood or serum is 5 to 20 mg/dL or 1.8 to 7.1 mmol urea per liter 14. Thus, physicians must not misdiagnose renal dysfunction for observing plasma BUN > 8.0
The use of urea ((NH 2) 2 CO) as a source of nonprotein nitrogen (NPN) has been applied on a large scale in ruminant diets, mainly to reduce production costs. (NH 2) 2 CO is hydrolyzed by ureolytic bacteria in the rumen into ammonia nitrogen (NH 3-N) and incorporated by ruminal microorganisms for microbial protein production, which is very
2023年3月8日 The body excretes blood urea in urine and milk. Urea nitrogen (N) levels in blood plasma, blood serum and milk of an individual cow are highly related. Therefore, MUN values are representative of urea levels of blood and other body fluids. Because MUN is a breakdown product of protein, it can be used to monitor protein status of cows.
2021年6月7日 29.9 *(18/100) = 5.382 kg nitrogen as a result of adding DAP.The remain quantity of nitrogen (10-5.382=4.618 kg nitrogen must be add fro urea which equal to (4.818 *(100/46) =10.473 kg urea for
2023年2月4日 Feed and residual samples were dried (60 °C), then milled (1 mm) in a Wiley mill (Swedesboro), pooled for each sheep, and kept at −20 °C. Both OWU and OWSU silages had a greater CP digestibility than other silages due to their urea content making more nitrogen available for fermentation (Van Soest, 1994). Overall, OWS,
2021年5月26日 Results of the blood urea nitrogen test are measured in milligrams per deciliter (mg/dL) in the United States and in millimoles per liter (mmol/L) internationally. In general, around 7 to 20 mg/dL (2.5 to 7.1 mmol/L) is considered normal. But normal ranges may vary, depending on the reference range used by the lab, and your age.
2020年10月23日 The U.S. pulp and stone industry produces 5 million Mg of solid waste each year in the form of sludge. Currently most of this waste is landfilled, but land application of sludge has several potential benefits. However, the utility of pulp and stone sludge as a fertilizer is hampered by its low nitrogen content. The purpose of this study is to improve
2023年3月31日 Rice cultivation is facing a situation where limestone production stagnates while nitrogen fertilizer (NF) application continues to increase. The effectiveness of the NF residues from the limestone season on the growth of rotating broad beans is unclear. High NF use in limestone cultivation also affects the nitrogen supply through soil organic nitrogen (SON)
Accordingly, human milk contains several non-protein nitrogenous molecules, including urea at high abundance. This project investigates the degree to which urea is utilized as a primary nitrogen source by Bifidobacterium longum subsp. infantis and incorporation of hydrolysis products into the expressed proteome.

2021年10月15日 It is a feasible and effective strategy to realize the C N bond formation and amines generation by coelectrolysis of carbon-containing and nitrogen-containing feedstocks. [5-8] As one of the important amines in the fields of agriculture and industry, the conventional synthesis of urea includes two consecutive processes. []Nitrogen reacts
尿素是生物体内含氮化合物分解的终产物，在尿酶催化下分解转化成氨。血液尿素氮是肾功能的主要指标之一。在碱性条件下，尿酶水解尿素产生氨，氨与次氯酸反应生成氯胺，再与酚衍生物作用生成绿色吲哚酚，在630nm 处有特征吸收峰。
2021年11月16日 Milk urea nitrogen (MUN) is an indicator of the efficiency of protein utilization in dairy cows [1,2,3,4].Low values of MUN are connected with very poor milk production [5, 6], while higher values are connected to increased infertility [].The nitrogen excreted through urine and fecal matter contributes to environmental pollution and high
