POTENTIAL APPLICATION OF MICROALGAE IN ANIMAL PRODUCTION

This article discusses the possibility of using microalgae in livestock production, with special reference to reducing harmful and noxious gas pollutant emission.Taking into consideration ongoing climate crisis the issue linked with reduction of gases from intensive animal production is a key important.Research shows that photosynthesizing properties of algae can be utilized for CO2 sequestration.Microalgae may be used as a method to reduces emissions of harmful gaseous components from natural fertilizers while enriching microalgae in N and P from manure or slurry.It is also worth noting that studies' results show microalgae biomass may be used as a substrate for biofuel production and as a feed additive partly replacing cereals in animal diets.The possiblity of applying microalgae as a feed additive was confirmed in studies, where microalgal powder (MAP) was used in layer feeding.MAP -supplementation causes improvements in egg quality.Microalgae may be used as an alternative to fish oil in cows' diets, causing increase in content of cis-9, trans-11 CLA in milk.Another important use of the unicellular algal biomass in agriculture is biogas production.The aim of this article is to review and systematize the current state of knowledge on topic of the application microalgae in animal production.
