Import 25-Hydroxyvitamin D3 Animal Feed Additive — Buy in wholesale FOB from Supplier in China

25-Hydroxyvitamin D3 (25-OH-D3, CAS 63283-36-3) is the hepatic metabolite of cholecalciferol and the principal circulating form of vitamin D in mammals. The product supplied年会 supplied by Hubei Horwath Biotechnology is a microencapsulated powder containing 1.25% active 25-hydroxyvitamin D3, formulated on zeolite or rice chaff carrier with BHT antioxidant. The molecular formula is C27H44O2.H2O with a molecular weight of 418.7 g/mol, structured on a cyclopentane polyhydrophenanthrene backbone derived via 25-OH-7-DHC photorearrangement.

The 1.25% concentration is achieved through microencapsulation, a process that stabilises the hygroscopic active against oxidation and environmental degradation. The carrier blend (zeolite powder and rice chaff) provides flowability and uniform dispersibility in premixes. BHT is included as a standard antioxidant. The product is not impacted by intestinal malabsorption, liver damage, or hepatic dysfunction, as it bypasses the 25-hydroxylation step required for standard vitamin D3. Typical industry formulations range from 0.5% to 2% active content; this 1.25% grade sits in the mid-range for broiler and layer premix applications.

This feed additive targets poultry integrators, premix manufacturers, and large-scale livestock operations requiring optimised calcium-phosphorus metabolism. Applications include broiler growth optimisation, layer eggshell quality improvement, and sow bone integrity programmes. The 25 kg bag packaging suits industrial feed mill operations. Buyers should confirm with the supplier whether the batch is produced under FAMI-QS or equivalent feed safety certification, as this is not stated in the listing.

Hubei Horwath Biotechnology Co., Ltd. is located at No. 46, Guishan Road, National High-Tech Industrial Development Zone, Xianning, Hubei Province, China. The supplier holds a 'harbor' trust tier, which is an entry-level verification status. The response rate is recorded at 0.00% with zero average response hours, indicating no confirmed buyer engagement through the platform's messaging system. The listing provides a detailed technical description including molecular structure, synthesis route, and formulation details, suggesting internal technical competence in vitamin D metabolite production.

The company profile does not disclose manufacturing certifications (such as ISO, FAMI-QS, or GMP+), annual production capacity, export markets served, or years in operation. No client references or third-party audit information is present. The address places the operation in Xianning's high-tech zone, a hub for pharmaceutical and biotech manufacturing in Hubei Province. Buyers should independently verify GMP compliance, feed additive registration status in the destination market, and batch-specific Certificates of Analysis before committing to purchase.
