| Abstract |
| Purpose: Animal waste is a major source of environmental pollution and greenhouse gas emissions. However, it also contains valuable nutrients that can be recovered and reused for other purposes. In this project, we developed a novel technology that converts animal waste into fish feed, using enzymes and supplements. This technology can reduce the environmental impact of animal farming and aquaculture, and provide a sustainable and cost-effective source of protein for fish. Method: In this study, bovine manure was procured from local dairy farms, with the cattle's diet primarily comprising corn, wheat, barley, and assorted forage. After the sorting process, enzymatic hydrolysis was employed to break down the proteinaceous fibrous materials into smaller, more assimilable molecules. Additionally, a tailored blend of nutritional supplements was incorporated to augment the feed's overall nutritive profile. In the process that has been carried out, besides removing pathogens, the edible part of the processing and the absorbable part also increases. The resultant product, designated as 'Manure Fish Food,' is derived predominantly from the manure above, and is posited as a sustainable product. Results: Laboratory assessments of ‘Manure Fish Food’ have demonstrated a marked increase in its core nutritional components. The protein content was found to be 51.48% higher, fiber content increased by 64.33%, and fat content rose by 53.29%, all relative to manure, the initial raw material employed. These substantial increments highlight the product’s enhanced nutritional profile, which could significantly contribute to the advancement of aquaculture feed components. Conclusions: Consequently, the analytical results substantiate that ‘Manure Fish Food’ is composed of elevated levels of protein and fat, alongside an enhanced digestibility profile when juxtaposed with conventional fish feed. These attributes collectively contribute to the potential of ‘Manure Fish Food’ to bolster the growth, vitality, and survivability across diverse piscine species, thereby presenting a viable nutritional solution in aquaculture practices. |
