Abstract
Industri pakan ternak modern membutuhkan sumber asam lemak omega-3 (DHA) yang berkelanjutan dan halal sebagai pengganti minyak ikan. Pakan ayam diproduksi menggunakan biomassa utuh (whole-cell) mikroalga Schizochytrium sp., yang diformulasikan dengan jagung sebagai pakan dasar. Schizochytrium sp. dikultivasi secara heterotrofik melalui fermentasi fed-batch untuk mencapai kepadatan sel dan akumulasi DHA yang tinggi. Biomassa dipanen melalui sentrifugasi dan diproses menggunakan spray drying yang terintegrasi dengan mikroenkapsulasi untuk melindungi DHA dari oksidasi, menghasilkan tepung mikroalga yang stabil. Pendekatan biomassa utuh ini memungkinkan integrasi langsung tepung mikroalga (kaya DHA, protein, dan mineral) ke dalam formulasi pakan berbasis jagung, sehingga menghilangkan kebutuhan ekstraksi minyak yang kompleks dan mahal. Metode ini menawarkan solusi yang lebih sederhana, hemat biaya, dan berkelanjutan untuk menghasilkan pakan ayam fungsional yang kaya nutrisi.

The modern animal feed industry requires a sustainable and halal source of omega-3 fatty acids (DHA) as a substitute for fish oil. Chicken feed is produced using the whole-cell biomass of the microalga Schizochytrium sp., which is formulated with corn as the base feed. Schizochytrium sp. is cultivated heterotrophically through fed batch fermentation to achieve high cell density and DHA accumulation. The biomass is harvested via centrifugation and processed using spray drying integrated with microencapsulation to protect the DHA from oxidation, resulting in a stable microalgal meal. This whole-cell biomass approach allows for the direct integration of the microalgal meal (rich in DHA, protein, and minerals) into the corn-based feed formulation, thereby eliminating the need for complex and costly oil extraction. This method offers a simpler, more cost-effective, and sustainable solution for producing nutrient-rich functional chicken feed.
