Summary
Discover how feed grade magnesium oxide enhances livestock health, milk yield and growth performance. Premium animal nutrition solutions from China.

If you are sourcing feed grade magnesium oxide for your animal nutrition formulations, you have probably noticed: not all MgO is created equal. At Richase, we have spent over a decade helping feed mills, premix blenders, and livestock operations across 30+ countries build reliable animal nutrition solutions around magnesium oxide. Our flagship product — High Purity Feed Grade Magnesium Oxide — exemplifies the purity and consistency that professional feed formulators demand.

Why Feed Grade Magnesium Oxide Matters for Animal Nutrition Solutions
Magnesium is not optional in livestock diets. Ruminants cannot store magnesium efficiently and need steady dietary supply. When magnesium runs low: grass tetany in grazing cattle, reduced milk fat in dairy cows, slower weight gain in feedlots. A well-formulated MgO animal feed additive corrects this at the source. FAO projects rising meat consumption through 2030, making livestock mineral supplements not just growing demand but a baseline requirement.
What Defines Quality in Feed Grade Magnesium Oxide for Animal Nutrition Solutions
Three numbers dominate procurement: purity, particle size, and heavy metal limits. For ruminant applications, 85-92% MgO is the workhorse range. Particle size sweet spot for ruminant magnesium oxide: 80-200 mesh. Heavy metals are non-negotiable. We test every batch via ICP-MS.

Livestock Mineral Supplements: Species-Specific Animal Nutrition Solutions
Dairy cattle: 0.2-0.4% of dry matter intake. Beef feedlots: MgO with ionophores for feed efficiency. Poultry: 0.05-0.1% with higher purity. Understanding dairy cattle feed minerals requirements is critical.
The China Advantage in MgO Supply for Animal Nutrition Solutions
China produces 70% of global magnesia. Liaoning Province accounts for 85% of reserves. Our facility has 100,000+ tons mining and 300,000 tons production capacity. Bayuquan port: 91km. Dalian: 257km.
Preventing Grass Tetany with Ruminant Magnesium Oxide
Grass tetany remains one of the most costly metabolic disorders. Prevention: supplement with ruminant magnesium oxide. Studies show higher surface area MgO delivers faster rumen solubility. European and North American dairies switching to high-reactivity feed grade magnesium oxide reported measurable milk fat improvements.

Regulatory Compliance and Quality Assurance for Animal Nutrition Solutions
EU: FAMI-QS. North America: AAFCO. Our feed grade magnesium oxide carries FAMI-QS, ISO 9001, ISO 14001. Full batch traceability. Testing: MgO (XRF), heavy metals Pb/As/Cd/Hg (ICP-MS). COA with every container.
Dairy Cattle Feed Minerals: What Producers Want in 2026
Dairy nutritionists increasingly request granular MgO (0.2-2mm) for dairy cattle feed minerals. Reduced dust, better TMR homogeneity. Another trend: combined premixes — livestock mineral supplements blended and bagged to spec.
Procurement Checklist for MgO Animal Feed Additive Suppliers
- Request COA from last 3 batches.
- Ask about heavy metal methodology — ICP-MS.
- Verify certifications: FAMI-QS, ISO 9001, ISO 14001.
- Request physical sample.
- Ask about lead time.
- Evaluate responsiveness.
