Currently, expensive bioprocessing steps are used to acquire the functional components that could achieve the desired biofunctionality of CV, in particular to maintain productivity and support health in broilers. This makes CV an expensive feed ingredient that can only be used in low inclusion levels, otherwise the cost of the feed is too high. However, it is not clear whether low CV inclusion levels have positive effects on broiler production and immune response. This study investigated whether the addition of CV biomass, at a low inclusion level of 0.8%, to broiler diets maintained the functional properties of microalgae and improved broiler productive performance. We found that the addition of 0.8% CV biomass affects the immune response, and has positive effects on the overall productive performance of broilers.
