The tons of keratin waste are produced by the poultry and meat industry which is an insoluble protein-rich material found in hair, feathers, wool, some epidermal wastes. These products could be degraded recycled to recover protein, can save our environment. One potential strategy achieve this target use microbial biotreatment more convenient, cost-effective, environment-friendly formulating hydrolysate complexes that administered as protein supplements, bioactive peptides, or animal feed ingredients. Keratin degradation shows great promise for long-term amino acid recycling.

Enhancing the Nutritional Quality of Low-Grade Poultry Feed Ingredients Through Fermentation: A Review

Agriculture, Journal Year: 2025, Volume and Issue: 15(5), P. 476 - 476

Published: Feb. 22, 2025

Feed accounts for up to 80% of poultry production costs, with high-quality grains such as soybean meal and corn traditionally serving primary ingredients. However, increasing costs competition these have driven interest in low-grade unconventional feed ingredients, including by-products like rapeseed cottonseed meal. These alternatives are often constrained by high fiber content, anti-nutritional factors, reduced nutrient bioavailability. Fermentation has emerged a promising strategy address limitations, enhancing digestibility, palatability, antioxidant properties while degrading harmful compounds tannins, trypsin inhibitors, free gossypol. Solid- liquid-state fermentation techniques utilize microbial inoculants, lactobacilli Bacillus species, enzymatically break down complex macromolecules, thereby releasing essential nutrients. When combined pretreatments enzymatic hydrolysis, significantly improves the nutritional quality ingredients reducing without compromising health or performance. This review examines mechanisms, benefits, challenges production, underscoring importance further research optimize parameters, identify novel strains, ensure scalability safety industrial applications.
