Assessment of the use of seaweed additives on health status and performance of dairy cows

Monday 24 January 2022

Overview: There is a growing emphasis in national and international policy directives to reduce the usage of antibiotics in farming, a practice that is leading to the development of human pathogens resistant to antibiotics. In particular, Ireland’s National Action Plan on antimicrobial resistance aims to implement policies and actions to prevent, monitor and combat antimicrobial resistance across the health, agricultural and environmental sectors. As part of the Seafood Processing Innovation Scheme, BioAtlantis has examined the role of seaweed-derived bioactives in modulating the immune system and enhancing health parameters of relevance in dairy cows.


Aim: The aim of this study was to examine the effects of supplementing dairy cows with a seaweed extract manufactured by BioAtlantis on indicators of bioenergetic status, immunity, health status and productivity. The trial was undertaken by scientists in Teagasc Moorepark Animal and Grassland Research and Innovation Centre in Fermoy, Co. Cork, on a herd predominately composed of Holstein-Friesian and Jersey crossbred cows.


Results: This study provides evidence that the seaweed extract manufactured by BioAtlantis has effects in dairy cows, including indicators of metabolic status, immune function and reproductive performance. The results provide a platform for undertaking additional trials aimed at modulating the immune system and enhancing health parameters of relevance in dairy cows.


The Seafood Processing Innovation Scheme is supported by Bord Iascaigh Mhara and the European Union, a scheme aimed at promoting business innovation, processing and new product development.
