Product name: Vitamin D3
Size: s210
Molecular Formula: C27H44O
Shelf life: 2 years
Description:
Vitamin D3 500 is a free-flowing, uniform shaped granular powder with a spherical coating. The product contains Vitamin D3 , which is existing uniformly in a Starch-coated matrix consisting of Gelatine and Carbohydrate with BHT added as an antioxidant. Therefore, the product could present the optimal stability. The product is especially designed for animal feed additives. Each gramme of  vitamin D3 500 contains 110,000 particles and the diameter of particle ranges from 150μm to 450μm.
Structural formula:

Molar mass: 384
Formula: C27H44O
Speciation:

Content: 500,000 IU/g (by HPLC) .
Loss on drying 5% max.
Particle Size:
100% smaller than 850μm(through US standard mesh 20).
Min. 90% smaller than 425μm(through US standard mesh 40).
Max.10% smaller than 150μm(through US standard mesh 100).
Bulk density: approximately 0.6gram/cm3.
Application:
Vitamin D3 500 is for preventing animal from rickets, rationalizing metabolic utilization of Calcium and Phosphorus, especially for enhancing absorption of Calcium and Phosphorus in the intestine and adjusting excretion of Calcium and Phosphorus in the kidney. Additionally, it could efficiently control Calcium and Phosphorus reserved in the cadres and promote conversion rate of Calcium and Phosphorus in the cadres so as to promote growth of animal cadres.
Dosage:
The demand of Vitamin D3 is depending on Calcium and Phosphorus supplements. A deficiency in Calcium and Phosphorus or an inappropriate proportion always results in an increasing demand for Vitamin D3. Therefore, the standard content of Vitamin D3 in feed per kilogram is 1000-5000 IU according to animal species and the production capability.
Stability:
The coating process and the presence of BHT as an antioxidant for vitamin D3 500 ensure optimal stability in premix. The product can be resistant to all different types of mixing environment whether chemical (including water, oxygen, trace mineral, acidity and alkalinity etc.) or physical (temperature, compression, abrasion etc.). The outstanding stability can be ideally suited to all processing technologies for animal feedstuff and supply high-grade feed products so that the premixers and feed producers can be in a position to make a commitment on the quality within the shelf-life period.
Mixability:
The physical characteristics of vitamin D3 500 (number of particles, particle size, bulk density and flowability) can supply an effective guarantee for the uniform and stable distribution of Vitamin D3 after mixing with other feed ingredients and as well as avoiding demixing during transport and loading.
Biological efficacy:
The special coating process of vitamin D3 500 ensure excellent biological availability in both monogastrics species and ruminants. In monogastrics, the feed-grade coating dissolves in the digestive tract, allowing the released Vitamin D3 to be quickly and efficiently absorbed in the intestine. In ruminants, the coating passed through the rumen without dissolving and is later absorbed in the intestine.
