Article Synopsis
- The study investigates the effectiveness of ultrafine particles (UFPs) like CoO and MnO as bactericidal agents, highlighting their potential to combat antibiotic resistance while being environmentally safe.
- Using advanced techniques, researchers analyzed how these UFPs affect bacterial cells' bioluminescence and morphology, revealing significant damage to cell walls and structures at effective concentrations.
- The research suggests safe dosage limits for using these UFPs in animal feed, while also acknowledging the need for further studies on their toxic effects on bacteria and other biological systems.
Article Synopsis
- The study investigates how a probiotic supplement affects the gut microbiota and mineral metabolism in dairy cows, building on existing contradictory data about the gut microbiome's role in mineral regulation.
- Fifteen cows were given a specific probiotic daily for a month, and their gut microbiota and serum mineral levels were analyzed using advanced sequencing and mass spectrometry techniques.
- Results showed that the probiotic improved gut microbiota diversity, increased levels of essential minerals like calcium and zinc, and altered other serum parameters, suggesting probiotics may enhance mineral nutrition in cattle, although their impact on milk production remains to be studied.
Background And Aim: At present, detailed studies are being conducted to confirm the safety of the use of metal-containing ultrafine particles (UFP) in animal feeding, preventing the possibility of negative effects on productive qualities and physiological state, as well as on the environment and final consumer, that is, humans. Thus, the purpose of this research was to study the safety of cobalt- and manganese-containing UFP (UFP CoO, MnO UFP) together with (PB) herb extract in a bioluminescence inhibition test, as well as the effect of this composition on ruminal digestion .
Materials And Methods: The safety of the studied samples was determined using a multifunctional microplate analyzer TECAN Infinite F200 (Tecan Austria GmbH, Austria), recording the luminescence value of the bacterial strain (Ecolum, JSC NVO Immunotech, Russia).
Serum Mineral Levels in Dairy Cows Transiting from Feedlot to Pasture.
Biol Trace Elem Res
February 2024
The objective of the present study was to evaluate trace element and minerals levels in the serum of cows transiting from diets consumed in feedlot or under grazing. A total of 30 healthy 5-6 years old cows of the Red Steppe breed were involved in the study. Blood samples were collected at the end of the feedlot period (end of April) and during the pasture period (end of June).

An original method was used for the preparation CuO-Ag Janus like nanoparticles by simultaneous electrical explosion of twisted Cu and Ag wires in a mixture of argon and oxygen gases. The bioluminescence inhibition on recombinant strain E.
