The goal of the study is the opportunity for the combined use of iron nanoparticles with arginine
and other amino acids in poultry nutrition. The iron nanoparticles (nanoFe) were obtained through hightemperature condensation and had a size of 80 ± 5 nm. The duration of the experiment on broiler chickens is 28
days. During the study of the amino acid composition of poultry liver, there was an increase by 3.1-4.2% in the
content of arginine when feeding nanoFe in the period of 7-28 days of the experiment; and by 3.5-3.7% of amino
acids with nanoFe on day 7 of the experiment. Adding nanoFe in poultry’s diet is accompanied by an increased
content of NO-metabolites in the liver by 3.1-3.5%. The enrichment of the food with nanoFe helped to increase
the iron concentration in the body of poultry by 5.3% during the experiment; when combined with arginine – by
4.5%. The total pool of iron in the body of poultry has increased by 13.0%; when combined with arginine –
14.6%, amino acid complex – 17.3%. Using nanoFe in compound feed resulted in an increase of erythrocytes in
blood, and with the additional feeding of amino acids the increase was more significant. The most body weight
of poultry at the end of the experiment is noted when combined feeding nanoFe and the complex of amino acids.
The use of amino acids in feeding without the inclusion of nanoFe is accompanied by an increase in the body
weight by 6.1-9.4%.
