Enhancing the fire safety of epoxy resin (EP) concomitant with less mechanical performance degradation is still a challenge for traditional flame retardants. Hence, polypyrrole (PPy) was used as a fil...
Two experiments were performed to evaluate the effects of coated slow-release urea on nutrient digestion, ruminal fermentation, nitrogen utilization, blood glucose and urea concentration (Exp 1), and ...
Viscous gums enhance viscosity in the upper gastrointestinal lumen, quickly disturbing motility and promoting fluid secretion.
The optimum enrichment parameters of main omega-3 polyunsaturated fatty acids (ω-3 PUFAs) from Rana egg oil were investigated. Firstly, it was optimized the saponification condition. Secondly, the PUF...
The importance of urea nitrogen reutilization in the amino acid economy of the host remains to be clarified.
Recent findings have shown that microbial nitrogen flow and digestible energy of diets are increased when urea is combined with a slow-release urea (SRU) in diets with a starch to acid detergent fibre...
An isotope dilution method using [U-13C]glucose and [1-13C]leucine (Leu) was conducted to evaluate the effects of rice straw supplemented with urea and molasses (RSUM-diet) on plasma glucose and Leu t...
Leucaena silage was supplemented with different levels of molasses and urea to study its nutritive value and in vitro rumen fermentation efficiency. The ensiling study was randomly assigned according ...
SCR后处理技术是目前降低柴油机NO x 排放量的主流技术,首先基于自主开发的SCR控制系统,阐述了系统的组成、工作及反应原理。其次通过协调控制策略以确保系统内部各模块运转正常,通过原机排放模型和化学反应动力学模型作为前馈控制得到尿素基本供给量,通过排温修正模型进行瞬态排温修正,利用发动机排温和储氨量的对应关系对氨泄漏进行有效控制,根据OBD法规要求当发动机NO x 排放量超标时进行报错。最后对系...
The presented chromatographic procedure is especially suitable for preparation of reference sample sets, very accurate and precise research purposes or rapid clinical diagnostic with smaller sampl...
The objective of this study was to determine how the concentration of milk urea (MU) and FPCM production affect reproduction in selected Holstein dairy herds in the Czech Republic. A retrospective, ob...
The milk urea concentration (MUC) is a respected indicator of the health and nutrition status of dairy cows. It is in relation to their reproduction performance, longevity and technological milk indic...
Milk urea concentration (MUC) is a suitable indicator of the health and nutrition state of dairy cows. MUC is in relation to their reproduction performance, longevity and technological milk indicators...
The objective of this study was to determine how non-nutritional factors such as herd, parity, days in milk, milk production, and milk components affect the concentration of milk urea. A retrospective...
Two experiments were conducted to investigate the effects of dietary crude protein level and degradability on milk urea nitrogen (MUN) content. In experiment 1, twelve multiparous lactating cows avera...
