Summary. The aim of the research was to evaluate the ability of silver nanoparticles to affect the level of accumulation and intensity of toxic effects of cadmium in organisms of laying hens of the Lohmann White cross. Twenty two-week-old laying hens were the object of the research, their liver and blood was the material. Four groups were formed for the experiment. The first one was the control (chickens were kept on standard food and water diet). The second experimental group served as the background of the toxic effect of cadmium (CdSO4 x 8H2O) in bodies of birds, which was fed in bread boluses at a dose of 1/10 LD50 (52.5 mg/kg) during 15 days. In the third and fourth groups the oral administration of cadmium sulfate was combined with addition of silver nanoparticles in water in the doses of 14.0 and 7.0 mg/kg, respectively. Cadmium sulfate accumulated actively in the liver of hens from the second group (in 15 days of toxicosis IWP was 962.44 ± 22.57 standard units), which was accompanied by a decrease in red blood cells level in blood by 27.74%, the increase in hemoglobin content at 11.55 % and in saturation of erythrocytes by hemoglobin on 81.59%. However, the hemoglobin of blood was represented by methemoglobin on 49.27%. By the end of the experiment silver nanoparticles at the daily dose of 14 mg/kg against the background of cadmium intoxication reduced the degree of cadmium accumulation in chicken liver by 29.13%, increased the number of red blood cells on 32.30%, hemoglobin , which was represented by methemoglobin by 16.58%–on 29.49%, maintained a saturation of erythrocytes by hemoglobin. The combined effect of cadmium sulfate with silver nanoparticles on poultry organisms at the daily dose of 7 mg/kg was characterized by more pronounced anti-toxic effect. So in chicken liver it was accumulated less cadmium by 48.41%, the number of erythrocytes increased on 34.02%, hemoglobin content grew on 20.89%, and methemoglobin consisted only 5.70% in it.
