Effect of colloidal silver nanoparticles on broiler chickens gut microbiota

M. D. Kucheruk, D. A. Zasiekin


We tested the colloidal silver nanoparticles as modern drugs for effective long-term reduction of microbial contamination in the air of broiler houses by intestinal rehabilitation of broiler chickens and simultaneous disinfection of water pipes and drinking water. The effective concentration of these solutions was determined. Cobb-500 broilers were used for the experiment. During the experiment, we set quantitative and qualitative composition of microflora of the intestinal contents of broiler chickens. Air samples were examined by sedimentation. We studied the productivity indices of chickens and product quality. Colloidal nanoscale silver solutions delicately spend intestinal sanitation, eliminating pathogens, virtually affecting the symbiotic intestinal flora. Siler nanoparticles helps to rationally correct the microbiocenosis of the intestines of broiler chickens: the composition of symbiotic microorganisms remains virtually unchanged against a statistically significant decrease in the amount of pathogenic and opportunistic microflora. This contributes to the intensification of the digestive process and increases the immune response to the continuously entering with food and water pathogenic microorganisms. The dependence between microbial composition of the intestines of birds and sanitary-hygienic state of air environment of broiler houses were proved.
