Red seaweed


  • Prebiotic
  • Antibacterial
Red seaweed (Sarcodiotheca gaudichaudii) is a succulent seaweed known to be a rich source of lipids, polysaccharides, proteins, bioactive compounds and of secondary metabolites such as polyphenols as well as of minerals, which impart several health benefits. Specific applications related to poultry include:
  • Egg quality: Research indicates that dietary supplementation using red seaweed inclusions can act as a potential prebiotic to improve performance, egg quality, and overall gut health in layer hens.
  • Antibacterial: When added to the diet of hens, red seaweed reduced the prevalence of Clostridium perfringens in the GI tract of the birds.

Poultry Specific Studies

Chickens0.05-0.25% dietHad a beneficial effect on fecal microbes as Lactobacillus sp. counts increased and Escherichia coli and Salmonella sp. counts decreased on day 42. Histopathological examination of the intestine confirmed that seaweed dietary supplementation enhanced the heights and widths of the villi. Furthermore, the emission of fecal gases (NH3 and H2S) decreased linearly in broilers fed seaweed-supplemented diets.B Balasubramanian et al., 2021
