Problem
Livestock production generates large amounts of methane, a potent greenhouse gas, contributing significantly to climate change while also requiring substantial feed resources to maintain animal productivity.
Solution
Sea Forest produces SEAFEED™, a feed supplement derived from the bio‑active compounds of the native Tasmanian seaweed Asparagopsis. By incorporating very low quantities of this supplement into livestock diets, methane emissions from ruminants are markedly reduced. The company cultivates the seaweed and applies proprietary extraction, stabilization, and concentration processes to deliver a consistent, scientifically validated product. SEAFEED™ therefore helps producers lower their environmental footprint without compromising animal health or growth performance, aligning agricultural output with climate‑mitigation goals.
Target Audience
Primary customers are cattle and sheep producers, feed manufacturers, and agribusinesses seeking to reduce enteric methane emissions and improve the sustainability of their operations.
Features
