Cholesterol 91% Feed Ingredient for Penaeus spp. | Support Exoskeleton Formation
Cholesterol 91% is a targeted feed ingredient for Penaeus vannamei and P. monodon diets where a dependable sterol source is essential for exoskeleton formation, molting success, and steady biomass gain. By supplying a high-assay sterol in a practical, feed-ready form, this product helps formulators maintain consistent sterol levels even as they optimize protein and oil sources to meet cost and sustainability goals.
Designed for Penaeid Performance
Exoskeleton development: Cholesterol participates in the molting cascade and supports the post-molt hardening phase that underpins shell quality.
Growth continuity: Adequate sterol intake helps reduce molting bottlenecks that can lead to uneven size classes in ponds and raceways.
Feed flexibility: A high-content sterol source allows nutritionists to adjust marine oil and phospholipid inputs without sacrificing sterol targets.
Product Attributes
High assay (91%): Enables precise formulation and predictable contribution to total dietary sterol.
Good flow and dispersion: Engineered to blend evenly in premixes and complete feeds for hatchery, nursery, and grow-out.
Low impurity design: Manufactured to reduce off-odors and non-sterol residues that could affect palatability.
Integrating Cholesterol 91% Into Penaeus Diets
Hatchery and nursery feeds: Combine with marine phospholipids to support PL vigor, stress tolerance, and early exoskeleton development.
Grow-out formulations: Balance cholesterol with high-quality proteins and HUFA to sustain growth and FCR targets.
Broodstock rations: Where permitted, sterol balance is one piece of a broader conditioning plan that may include vitamins, antioxidants, and tailored fatty acid profiles.
Formulation Considerations
Inclusion ranges: Work with your nutritionist to define target sterol levels by life stage; typical programs specify cholesterol to complement natural sterols present in raw materials.
Compatibility: Blends with vitamin-mineral premixes and common binders. Maintain uniform mixing times to achieve consistent micro-ingredient distribution.
Processing: Standard pelleting conditions are generally suitable; avoid excess moisture that can increase caking risk during storage.
Quality, Compliance, and Documentation
We supply a full documentation packet with each lot, including COA and SDS. Batches undergo assay confirmation and impurity checks with traceability maintained end-to-end. On request, we provide suggested QC sampling plans, sieve profiles, and stability guidance.
Packaging and Logistics
Options include lined bags and sealed drums designed for humid environments.
Palletized shipments and scannable labels streamline receiving and FIFO control.
Support From Formulation to Scale-Up
Our team assists with trial design, data logging templates, and transition plans when replacing or supplementing sterol sources. Request samples and a tailored quotation based on your species portfolio and feed throughput.
With Cholesterol 91%, Penaeus diets gain a consistent sterol backbone that supports exoskeleton formation, uniform molting, and reliable performance across rearing systems.
