ABSTRACT. Nanotechnologies are of great
interest to researchers today. Their rapid development in recent decades is due
to the fact that
ultrafine particles (UFP), including metals, have completely different
properties than traditional forms of chemical elements. At the moment, the use
of UFP metals in the field of agriculture looks especially interesting. The
advantage of new forms of trace elements is that with their help it is possible
to overcome the negative effects inherent in traditional forms. So, when
compiling the diets of animals and birds, it is necessary to carefully select
the doses of elements in order to avoid their toxic effects, they also have a
low digestibility in the body and the possibility of developing oxidative
stress in animals. All this served as an impetus for studying the use of UFP as
sources of trace elements in the diet of farm animals. Thus, this review is
devoted to the use of ultrafine iron particles as a feed additive in the diets
of farm animals and poultry.
KEYWORDS: ultrafine particles, trace elements, iron, productivity, farm
