Product Overview
About This Product
25-hydroxyvitamin D3 (25-OH-D3) is the primary circulating metabolite of vitamin D3 and can be absorbed without hepatic conversion. Our powder form is produced through a controlled chemical synthesis and coating process, delivering consistent particle size and flow properties for uniform distribution in premixes and complete feed. All three grades are supplied as microcapsules or coated granules, giving outstanding stability and consistent activity through feed processing and storage.

Regulatory Reference
Inclusion Limits and Combination Rules
Figures from the Chinese Ministry of Agriculture Announcement No. 2625, effective 1 July 2018.
- Recommended inclusion (complete feed, expressed as vitamin D) — China

- Swine 50 μg/kg ｜ Broiler & turkey 100 μg/kg ｜ Other poultry 80 μg/kg
- Combination rules
- 25-OH-D3 must not be used together with vitamin D2. It may be used with vitamin D3, but the combined total must not exceed: milk replacer for piglets 250 ｜ other swine 125 ｜ poultry 125 μg/kg (40 IU vitamin D3 = 1 μg).
- Conversion
- 1 μg/kg = 1 mg/t. For the 1.25% grade, 1 g/t of complete feed delivers exactly 12.5 μg/kg.
- Note
- The figures above are the Chinese regulatory limits. For other destinations the limits of the importing country apply.
