Product Definition & Origin
Yucca Extract (CAS No.90147-58-3; English name: Yucca filamentosa, ext.) is a natural plant-derived product obtained from the roots, stems, and leaves of Yucca species (e.g., Yucca filamentosa, Yucca schidigera) through methanol, ethanol solvent extraction, concentration, and spray drying. Its production complies with Feed Additive Safety Guidelines and international phytochemical extraction standards (e.g., ISO 9001).
Core Active Components & Mechanisms
1): Steroidal Saponins
Function: Reduce intestinal surface tension, emulsify fats, and disrupt protozoal cell membranes (mitigating parasitic infections).Validation: A 0.05% inclusion rate improved feed conversion ratio in broilers by 4.2% (Poultry Science, 2020).
2): Polyphenols
Function: Chelate ammonia (NH₃) to reduce odor, suppress inducible nitric oxide synthase (iNOS) expression, and alleviate intestinal inflammation.
Data: In vitro studies show yucca polyphenols adsorb ammonia at 68 mg/g (Animal Feed Science and Technology, 2019).
3): Polysaccharides
Function: Act as prebiotics to stimulate Lactobacillus proliferation, balance gut microbiota, and reduce nitrogen emissions.
Application: Adding 0.1% to aquaculture feed decreases total nitrogen in water by ≥15%.

Functional Benefits & Certifications
1): Environmental Value
Ammonia Reduction: Inhibits urease activity, converting ammonia into microbial protein, reducing barn NH₃ levels by 30–50%.
Case Study: A commercial layer farm achieved a 22% reduction in manure treatment costs (China Poultry, 2022).
2): Health Benefits
Gut Protection: Reduces mucosal shedding (18% lower diarrhea rate in piglets) and enhances nutrient absorption.
Stress Resistance: Saponin-polysaccharide synergy lowers heat stress mortality.
3): Regulatory Approvals
Global: FDA GRAS certification (GRN No. 732)
EU：FEEDAP safety assessment.
China: Listed in Feed Additives Catalog (as "Natural Steroidal Sarsasaponin from Yucca," No. 11.301).
Market Potential & Research Frontiers
Market Size: Global yucca extract market reached $120 million in 2023, with a 6.8% CAGR (Market Research Future).
Emerging Applications: Antibiotic alternatives (synergistic use with Clostridium butyricum). Pet deodorants (37% of premium US cat litters now include yucca extract).
Technical Challenges: Saponin monomer isolation and purification technology (current industrial-grade purity ≤40%).
Conclusion
Yucca extract, with its trifunctional benefits-ammonia reduction, growth promotion, and antibiotic replacement-is evolving from a traditional feed additive into a critical enabler of sustainable livestock farming. As global demand for carbon neutrality and animal welfare grows, its value chain (cultivation-extraction-application) is poised for policy-driven and capital-backed expansion.
