Background: Single cell protein derived from food waste by Aspergillus niger serves as a cost-efficient and environmentally sustainable alternative to protein source in chicken feed. Microbial fermentation of agricultural byproducts generates high-quality, protein and reduces waste. These substrates, such as orange, sugarcane and pomegranate, generate single-cell protein, enhancing feed efficiency and improving protein utilization in poultry feed formulation. This method enhances chicken production, reduces feed expenses, and increases the availability of protein-rich meals and food security.
Method: Three agro-based substrates sugarcane, pomegranate and orange wastes, were tested to produce single cell protein by Aspergillus Niger. Biomass yields were measured, and it was found that orange waste supported greatest fungal biomass, and was therefore chosen for subsequent large scale production of Aspergillus Niger single cell protein. The 120 chicks were allocated at random into treatment group, each with 3 replicates of ten birds. Four diets with equal nitrogen and energy content were prepared containing SCP 0% (Control T1), 5% 10%, and 15% SCP, which replaced with soybean meal (T2 to T4). Separate starter and finisher diet were prepared for and fed to every replicate. At the end of the experimental time, record the growth performance as well as the feed conversion ratio. Liver histopathology were observed at 42 day experiment last day.
Result: The findings indicate that among the substrates tested, orange waste yielded more SCP biomass then the other substrates. Body weight gain in the groups 5% and 10% SCP diets was equivalent to the control within each feeding and the whole trial; however, it was significantly lower (p<0.05) in the group 15% SCP diets. SCP showed appropriate stability at 5%and 10% levels, highlighting the necessity for controlled incorporation at high doses.
Conclusion: SCP inclusion from 5% to 10% of broiler diets to enhance feed efficiency and promote sustainable production of proteins from waste resources.
