Use of nanoparticles of metals and non-metals in poultry farming

Abstract

The presented analytical review summarizes the data of the world and national literature on the features of the accumulation of microelement nanoparticles in the body, their effects on metabolism, redox processes and productivity of poultry. The attention is paid to the toxicity of various forms and sources of the considered elements, their mutual influence on bioavailability, antagonism and the rate of excretion. The need to study the peculiarities of the use of nanoparticles and their efficiency in the production of livestock products is constantly increasing. Evidence of the positive application of nanoforms of elements (zinc, silver, selenium, cerium, iron) in the diets of different species of farm poultry is considered due to their metabolic, antimicrobial action, influence on digestion and regulation of bowel function. Analyzed data indicate that nanoparticles of metals and non-metals in animal husbandry are an alternative to feed antibiotics for antibacterial action, increase the productivity of animals and poultry, can activate metabolism by stimulating the activity of hormones, optimize the immune response of the organism, induce syntheses and metabolism. Nanoparticles of metals and non-metals have been found to reduce the mineral antagonism in case of contact with the intestine, which contributes to the efficiency of digestion. Changes in the prooxidant-oxidant status of the blood of animals by the use of test nanoparticles and changes in homeostasis indices that are positive for poultry due to increased productivity, intensification of egg production, their weight and fertilization rate of hatching eggs have been established. Influence of nanoparticles on redox homeostasis and processes of lipid and protein peroxidation are established. The use of nanoscale drugs for use in biology, medicine, veterinary medicine, agriculture, and the need for further research to study all possible mechanisms of biological action of nanostructures are argued. Key words: trace elements, nanoparticles, poultry, feeding, silver, zinc, selenium, cerium dioxide.

Bacterial synthesis of nanoparticles: A green approach

“…The aspects of the interaction of nanoparticles and biological molecules, in particular with proteins, carbohydrates and lipids, remain multifaceted. For more practical use of nanoparticles in biology and medicine, it is necessary to focus on their metabolism in humans and animals (Grillone et al, 2017;Tsekhmistrenko et al, 2019). It is promising to study the possibility of synthesis of nanoparticles of different elements by one type of bacteria, which raises a number of new questions and problems.…”

“…Recently, more and more bacteria have been used for the synthesis of selenium, which is widely used in agriculture, the use of which increases the productivity of animals and poultry much better than inorganic forms Tsekhmistrenko et al, 2019). For this purpose, Rhodococcus aetherivorans BCP1 (Presentato et al, 2018), Acinetobacter sp.…”

Nanotechnology for Remediating Current Environmental Problems

“…Silver ions Nanoparticles (AgNPs) are an effective disinfectant of water against Escherichia coli (Baia et al, 2020) and the nanoparticles of titanium oxide destroys the Escherichia coli, hepatitis B virus in soil and remove aromatic hydrocarbons and phenanthrene (da Silva et al, 2016). Nanoparticles from titanium oxide (IV) are used in air purification, waste treatment, self cleaning of surfaces and as catalyst for water treatment as they are characterized by non-toxicity, low cost photo catalytic, electronic and ability to transform energy (Tsekhmistrenko et al, 2019). Adsorbants, mesoporoussilica materials in different modifications purify the gas phase from the contamination (Wang et al, 2019;Brigante et al, 2016).…”

Regulation of redox processes in biological systems with the participation of the Keap1/Nrf2/ARE signaling pathway, biogenic selenium nanoparticles as Nrf2 activators

“…Synthesized by the methods of bionanotechnology SeNP has many applications in the field of medical and pharmaceutical research. Selenium nanoparticles having oncosuppressive, antioxidant and antimicrobial activity are used in biology, medicine, agriculture (Bityutskyy et al, 2019;Tsekhmistrenko et al, 2019Akçay & Avcı, 2020;Kumar et al, 2020). Song et al (2017) synthesized biogenic nanoselenium nanoparticles (BNSe) with the participation of Enterobacter cloacae Z0206 bacteria, with the help of which sodium selenite was transformed into spherical selenium nanoparticles with a stabilizing protein shell, the particle size of which varied from 80 to 250 nm (on average 139.4 ± 7.4 nm).…”
