BACKGROUND: The marine plant Posidonia oceanica (L.) Delile can be a source of fibre to increase the efficiency of product costs. The aim of the present study was to assess the productive (milk production and performance) and metabolic (blood metabolites) effects of P. oceanica in the ration of dairy goats as a substitute for straw. Posidonia oceanica was used at 225 and 450 g day⁻¹ per goat in lieu of barley straw. RESULT: Supplementation with P. oceanica had no detrimental effects on the body weight, milk production and metabolic status of goats. Goats fed P. oceanica produced more milk fat, had a lower somatic cell count in their milk and showed a decreased risk of oxidative stress. CONCLUSION: Goats can be fed P oceanica at levels of up to 450 g day⁻¹ without detrimental effects on milk production and health, therefore P. oceanica can be a substitute for barley straw in the nutrition of goats. © 2015 Society of Chemical Industry
