Based on the incidence of diabetes, developing glucose sensors of superior performance with low-cost transition metals (TMs) has been the direction of many researchers, amorphous TMs with highly efficient electrocatalytic properties have attracted our interest. On this basis, amorphous...

This article examines the clinical health indicators of dairy calves, as well as data on laboratory tests of blood and urine, before and after conducting a scientific experiment on adding selenium and cobalt aspartate nanoparticles to their diet in the form of a feed additive. It was established...

The development of the agro-industrial complex is mainly associated with the provision of complete, nutritious and varied fodder. The greatest use of the genetic potential of livestock is largely dependent on high-quality and balanced fodder. Establishing the chemical composition is an important...

Deep eutectic solvent-liquid-liquid microextraction (DES-LLME) was combined with smartphone digital image colorimetry (SDIC) for the determination of cobalt as its chelate with 1-(2-pyridylazo)-2-naphthol. The final extract was placed in a quartz micro-cuvette inside a laboratory-designed...

Equid alphaherpesvirus type 8 (EqHV-8) is the causative agent of severe respiratory disease, abortions, and neurological syndromes in equines and has resulted in huge economic losses to the donkey industry. Currently, there exist no therapeutic molecules for controlling EqHV-8 infection. We...

The aim of this study was to compare levels of serum and claw tissue chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), copper (Cu), zinc (Zn) and selenium (Se) in healthy cattle with various claw lesions and to evaluate the relationship between claw lesion and trace element levels. A total of...

In the current research, a fast and sustainable air-assisted hydrophobic magnetic deep eutectic solvent-based dispersive liquid phase microextraction followed by UV-Vis spectrophotometry measurements was optimized for the extraction and determination of melamine in milk and milk-based products. The ...

This special issue contains 20 articles that discuss definong dietary requirements of trace elements by food producing animals; to elucidate factors influencing enzyme systems in which trace elements are a vital component; to determine if trace elements are required by food-producing animals; and...

A mineral feed additive in the composition of selenium and cobalt aspartate nanoparticles (OMEC-Co) was tested and an assessment was made of the growth rate and feed costs for calves of the dairy period of growing. As a result of the research, it was found out that calves from the control group...

This paper presents results for four types of morphology-controlled two-dimensional cobalt based tetrakis (4-carboxyphenyl) porphyrin metal-organic frameworks (2D Co-TCPP MOFs) with different catalytic properties for nitrite, and an electrochemical sensor was fabricated by the Co-TCPP MOF with...
