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

In recent years, nanotechnology wins key positions in various fields of knowledge The presented analytical review summarizes the data of the world and national literature on the features of the accumulationof microelement nanoparticles in the body, their effects on metabolism, redox processes and productivityof poultry.The attention is paid to the toxicity of various forms and sources of the considered elements, their mutual influenceon bioavailability, antagonism and the rate of excretion. The need to study the peculiarities of the use of ticles and their efficiency in the production of livestock products is constantly increasing. Evidence of the positiveapplication of nanoforms of elements (zinc, silver, selenium, cerium, iron) in the diets of different species of farmpoultry 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 feedantibiotics for antibacterial action, increase the productivity of animals and poultry, can activate metabolism by stimulatingthe activity of hormones, optimize the immune response of the organism, induce syntheses and metabolism. Nanoparticlesof metals and non-metals have been found to reduce the mineral antagonism in case of contact with theintestine, which contributes to the efficiency of digestion. Changes in the prooxidant-oxidant status of the blood ofanimals by the use of test nanoparticles and changes in homeostasis indices that are positive for poultry due to increasedproductivity, intensification of egg production, their weight and fertilization rate of hatching eggs have beenestablished. 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 furtherresearch to study all possible mechanisms of biological action of nanostructures are argued.
