Abstract

In this study, the economic and environmental feasibility of seaweed by-products as livestock feed ingredients was evaluated. In the last three years (2021-2023), the estimated average annual production of domestic seaweed by-products, including processing residuals from sea mustard and kelp, was 210,000 tons. The economic feasibility analysis of using seaweed by-products as livestock feed indicated a net benefit of 482,237 KRW per ton. Additionally, substituting seaweed by-products at 0.25% 0.5%, 1%, and 2% in livestock compound feed generated net benefits of 6.5, 12.9, 25.9, and 51.7 billion KRW, respectively. The potential market value was analyzed from an environmental perspective by examining the greenhouse gas reduction potential of seaweed additives. By adding 2% laver, 2% sea mustard, and 0.25% sea mustard sporophyll to the feed, greenhouse gas emissions could be reduced by economic values estimated at 10.8, 11.4, and 15.6 billion KRW, respectively. The findings of this study suggest that the use of seaweed by-products livestock as feed ingredients can generate economic and environmental benefits.
