| OCA16. Annotation of the output in English | From the achieved results we can state that the applied two preparations of humic substances in the nutrition of
broiler chickens did not have an impact on the monitored production parameter. A significant effect was found on
the content of calcium, phosphorus, chlorides, glucose, triglycerides and cholesterol. The direction of further research
will focus on the impact on the metabolism and quality of broiler products. |

| OCA18. Characteristics of the output's impact on socio-economic practice | A study evaluating the impact of humic substances on growth performance and selected blood parameters of broilers provides valuable insights for modern poultry production. The results show that the addition of humic substances can positively affect the growth, health and overall production efficiency of broilers.
Economic and economic impacts:
Improved growth performance: Broilers fed humic substances contribute to higher weight gain and better feed conversion, leading to lower cost per meat produced.
Increased feed efficiency: Better feed utilization means the main use of feed while maintaining or improving growth dynamics, which has direct economic benefits for producers.
Reduced need for antibiotics: Humic substances have potential antimicrobial and immunostimulatory properties, which can reduce the need for preventive antibiotic use and maintain sustainable poultry production.
Social and environmental impacts:
Improved poultry health: Positively influencing the blood picture of broilers, such as hemoglobin levels and optimizing metabolic parameters, leads to better immunity and mortality.
Sustainability and ecological: More efficient feed utilization and improved digestive processes can reduce unused nutrients in excrement, thereby limiting the environmental impact of poultry production.
Positive consumer perception: Reducing the use of synthetic additives and antibiotics can increase consumer confidence in poultry meat, thereby supporting the market for quality and safe foods. |

| OCA19. Characteristics of the output and related activities' impact on the educational process | Research focused on the evaluation of growth performance and selected blood parameters of broilers when supplemented with humic substances brings significant knowledge for the educational process in the field of agricultural, veterinary and biological sciences.
Benefit for students and professional training:
Integration into teaching – The results of the research can be used in courses focused on animal nutrition, poultry, digestive physiology and veterinary medicine, thus improving the connection of theory with practical applications.
Experimental education – Students can actively participate in similar research projects, thus gaining practical experience in the analysis of blood parameters, assessment of growth performance and statistical data processing.
Development of critical thinking – Interpretation of results and discussion of possible mechanisms of action of humic substances supports students\' analytical and scientific thinking.
Impact on scientific research activity:
Support for interdisciplinary projects – The research can serve as a basis for further studies in the field of alternative feed additives and their impact on animal health.
Preparation for a scientific career – The outputs can be used in the creation of diploma and dissertation theses, thereby increasing the level of education and supporting young scientists.
Connection with practice – Students can establish cooperation with farmers and feed companies, thus strengthening the practical application of their knowledge.
Impact on the education system:
Innovations in teaching – The use of modern knowledge about humic substances can lead to updating the curriculum and expanding teaching to include ecological and sustainable approaches in animal nutrition.
Raising environmental awareness – Studying the effective use of humic substances can contribute to greater emphasis on ecological production and reducing the environmental burden of poultry production. |
