Development of plant-origin feed additives for strengthening birds' immunity and increasing the nutritional value of eggs with omega-3 fatty acids Project leader Aija Ilgaža Duration 2023 - 2025 Research focus 1. Implementation of the "One Health" concept and species interaction studies in the context of climate change Source of funding National grant Project partners LU institute of Biology Joint-stock company "BIOLAT”Economic operator Ingus DruvaSauka parish farm "VILCINI”Vaidava parish farm "Skujas”Taurupe parish Savina farm "KALVĀNI”Association "LATVIAN UNITED POULTRY FARMING INDUSTRY ASSOCIATION" Description of project The aim of research To evaluate the composition of fatty acids in various microalgae and to explore the possibilities of enriching eggs with omega-3 fatty acids by adding microalgae to chicken feed mixtures. To evaluate the long-term impact of microalgae supplements with increased omega-3 fatty acids on chicken productivity and health, including immunity and digestive system function. The tasks of project: 1. Strengthen chicken immunity and improve productivity (meat and egg production) using microalgae biomass with increased omega-3 fatty acids, as well as evaluating its effectiveness in farms. 2. Develop and test a new microalgae mixotrophic cultivation method, the advantages of which have to be evaluated for further commercialization. 3. Improve the method for omega-3 extraction, where the obtained omega-3 fatty acids will be added to laying hen feed mixtures to serve as a source of protein, vitamins and antioxidants. Results In progress
