PhD defence, Friday 6 January 2023. Milani Bhagya Samarasinghe.

During her PhD studies, Milani Bhagya Samarasinghe investigated the functional properties of intact seaweeds as gut health promoting milk supplements for preweaning dairy calves. Intact seaweeds are of special interest in young animal nutrition mainly due to documented gut-health promoting effects of seaweed-derived extracts in piglets. However, knowledge on similar effects in preweaning calves is scarce. Therefore, Milani Bhagya Samarasinghe studied how three different types of seaweeds; Ascophyllum nodosum, Saccharina latissima and Ulva spp., supplemented in the milk at a dose of 5% (DM basis) affected gut health, systemic immune response, and overall growth performance of the preweaning dairy calves. The PhD study was completed at Department of Animal and Veterinary Sciences, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
