    Evaluación del medio de cultivo sobre la producción de macromoléculas funcionales en la cepa Chlorella sorokiniana UTEX 1230 como posible suplemento alimenticio para gallinas ponedoras
    (Universidad EAFIT, 2024) Múnera Betancourt, Amalia; Miranda Parra, Alejandra María
    Algae and microalgae are considered viable sources of protein for the poultry industry, used in animal nutrition to replace soybean meal (SBM) due to their high content of protein, fatty acids, vitamins, minerals and pigments. This study evaluates the production of functional macromolecules in the microalgae strain Chlorella sorokiniana UTEX 1230 as a supplement for laying hens. Cell growth was examined in different culture media with stimulant clinker powder, evaluating the bromatological composition, exopolysaccharides, fatty acid profile and in vitro digestibility, as well as the cost of production. These preliminary analyses are key to the implementation of microalgae as a protein source in poultry feed and warrant further in vivo testing.

    Evaluación del medio de cultivo sobre la producción de macromoléculas funcionales en la cepa Chlorella sorokiniana UTEX 1230 como posible suplemento alimenticio para gallinas ponedoras

    Alternative protein sources, specifically algae and microalgae, are considered as viable protein sources for the poultry industry. Currently, different species of algae are used in animal nutrition to replace soybean meal (SBM) due to their high content of protein, fatty acids, and the availability of vitamins, minerals and pigments. Determining the chemical and nutritional composition of a biological formulation, in addition to its digestibility, is the first step in evaluating its suitability for use in poultry feeds. The aim of this work is to evaluate different culture media in the production of functional macromolecules in the microalgae strain Chlorella sorokiniana UTEX 1230 as a possible feed supplement for laying hens. The cell growth of the microalgae was evaluated over time under different culture media and different levels of addition of the stimulant clinker powder, a product of the cement industry. The biomass obtained from this process was evaluated for its bromatological composition, exopolysaccharide content, fatty acid profile, and in vitro digestion using digestive enzymes from monogastric animals, in addition to an evaluation of its production cost. This evaluation represents a preliminary analysis to initially select the mode of production to implement these products as a protein source in poultry feed, and further in vivo testing is warranted.
