The article presents the results of a comparative analysis of the use of antibiotics and colloidal solution of silver nanoparticles for prophylactic purposes in broiler chickens. Legislation of Ukraine and the EU on organic poultry farming establishes a number of restrictions, prohibitions, in particular, the use of preventive antibiotics. However, there are still no recommendations for the use of permitted veterinary drugs. Silver has long been known for its antimicrobial properties; however, an excess of silver in the body can also lead to diseases such as argyria. In order to deepen the understanding of the mechanism of action of the solution of silver nanoparticles, their influence on the haematological parameters of broiler chickens, indicators of their productivity, quality and safety of the obtained products is determined. These indicators are analysed in comparison with similar indicators in the control group and the group of chickens receiving the antibiotic ‘Levoflox’ for prophylactic purposes. The results of the research show that the use of a colloidal solution of silver nanoparticles is cost-effective and increases the live weight of broiler chickens. Accordingly, the level of profitability of chicken-meat production at the poultry farm is increased with the use of the above-mentioned nutraceutical. The use of a solution of silver nanoparticles does not lead to its accumulation in tissues and organs of the animal body. Drinking a colloidal solution of silver nanoparticles has a positive effect on the physiological state of chickens, contributes to the preservation of poultry, and optimizes the sanitary and hygienic performance of premises for keeping birds. Economic analysis and productivity indicators of broiler chickens show that the use of 1% colloidal solution of silver nanoparticles is beneficial to broiler chickens, and the costs of its purchase and use are offset by significant increases in live weight of chickens, reduced feed conversion, and increased resistance to disease and safety.

Key words: antibiotics, colloidal solution, silver nanoparticles, productivity, broiler chickens.
