BIOLOGICAL EFFECTS OF SILICON OXIDE NANOPARTICLES ON BROILER CHICKEN

Abstract

The aim of the study is to increase the productive qualities of broiler chickens by including ultrafine silicon oxide into main diet. During the experiment, the biological effect of ultrafine silicon oxide on broiler chickens was established. Use of ultrafine SiO2 particles for poultry feeding contributed to an increase in the number of red blood cells and content of total protein and albumins. By the end of the experiment, the number of red blood cells in birds increased by 17.43% (P≤0.001) - in the blood of birds of the first experimental group, 16.51% (P≤0.01) - the second one, 20.80% (P≤0.001) - the third experimental and 21.71% (P≤0.001) - the fourth experimental group, compared with the indicator of the control group. The amount of total protein in blood serum of chickens of the first and the second experimental groups increased by 1.36-1.39 %, in the third and fourth ones there was a significant (P≤0.05) increase by 5.45 and 3.05%, respectively. The blood glucose content of chickens in the experimental groups is higher by 8.04-23.65% compared to this indicator with ones in the control group. During the experiment feed consumption per 1 kg gain of live weight decreased: in the first experimental group by 3.00 % in the second by - 0.50 %, the third - 6.00 % the fourth- by 4.50 %, compared to this with the control group. The chicken’s vibrancy of the first the experimental group was higher by 4.77 %, the second - by 6.20 %, the third - by 19.25 % and the fourth- by 11.59% than in the control one. Consequently, when converting the feed energy into the body energy of a broiler chicken, the energy conversion coefficient of the experimental group of poultry is higher than that of the control one by 7.16-21.76 %. Thus, the most optimal dose for further research was determined.
