Feed Grade Monopotassium Phosphate (MKP) – Solution for Animal Nutrition
Phosphorus and potassium are two essential macro-minerals in animal nutrition. However, not all phosphate sources offer the same bioavailability.
Through years of collaboration with feed mills and nutritionists, we have developed a high-purity, low-heavy-metal feed grade Monopotassium Phosphate (MKP) that delivers excellent solubility, absorption, and nutritional efficiency – supporting healthier livestock and more cost-effective feed formulations.
Why Feed Grade MKP?
| Parameter | Benefit |
| High bioavailability | Phosphorus absorption rate significantly higher than DCP or MCP |
| Dual nutrition | Supplies both phosphorus (P) and potassium (K) in one product |
| Excellent solubility | Ideal for liquid feed, drinking water supplementation, and premixes |
| Low heavy metal content | Safe for young animals and sensitive species (e.g., shrimp, fish, piglets) |
| Non-caking | Good flowability and storage stability |
Typical Applications
| Application | Function |
| Poultry feed | Supports bone development, eggshell quality, and growth rate |
| Swine feed | Improves feed efficiency and mineral balance, especially in weanling piglets |
| Aquaculture feed | Highly soluble – ideal for extruded and pelleted aquafeed; reduces phosphorus excretion |
| Liquid feed & drinking water | Quickly dissolves for direct mineral supplementation |
| Ruminant mineral premixes | Supplies readily available phosphorus for high-yielding dairy cows |

FAQ
Q: What is the difference between feed grade MKP and DCP?
A: MKP is highly water-soluble and offers >90% phosphorus digestibility in monogastric animals. DCP has lower solubility and digestibility (50-70%). MKP also supplies potassium, while DCP provides calcium. MKP is ideal for liquid feeds, drinking water, and high-performance formulations.
Q: Is MKP suitable for all animal species?
A: Yes. MKP is commonly used in poultry, swine, aquaculture, and ruminant feeds. It is especially valuable for young animals and aquatic species due to its high bioavailability and low heavy metal content.
Q: How should feed grade MKP be stored?
A: Store in a cool, dry, well-ventilated warehouse. Keep away from moisture and direct sunlight. Avoid contact with alkalis and reducing agents. Use original sealed packaging.
Q: Can MKP be used in organic feed?
A: Depending on local organic certification standards. Please consult your certifier. We can provide necessary documentation if required.
