Feed Grade Urea for Ruminant Nutrition
High-purity non-protein nitrogen (NPN) with 46% nitrogen for efficient ruminant nutrition.

Feed Grade Urea
Terafon® Feed Grade Urea
Functionality: High-quality non-protein nitrogen (NPN) source for ruminant nutrition and feed formulations.
Form: Free-flowing prilled granules or crystalline powder.
Appearance: White to off-white, odorless, uniform granules.
Solubility: Highly water-soluble (~1080 g/L at 20 °C).
Feed Grade Urea Detailed Specifications
Terafon® Feed Grade Urea (Carbamide, CAS No. 57-13-6) is manufactured under strict feed safety and quality management systems. Compared with agricultural or industrial urea, it offers controlled biuret levels, consistent granulation, and reliable nitrogen content, making it suitable for regulated animal feed and ruminant nutrition programs.
As an efficient non-protein nitrogen (NPN) source, feed grade urea supplies rumen microorganisms with readily available nitrogen, enabling microbial protein synthesis and improving fiber digestion and nutrient absorption.

Feed & Ruminant Nutrition Applications
Ruminant Feed Formulations
- Used as a concentrated non-protein nitrogen source in diets for cattle, sheep, goats, and other ruminants.
- Supplies nitrogen for rumen microbes, enhancing microbial protein production and improving forage utilization.
- Helps reduce dependence on high-cost true protein sources such as soybean meal.
Total Mixed Rations (TMR) & Feed Premixes
- Suitable for inclusion in TMR systems and compound feed premixes.
- Ensures balanced nitrogen supply and stable microbial activity throughout the feeding cycle.
- Supports consistent animal performance and feed efficiency.
Mineral Blocks & Protein Supplements
- Can be incorporated into mineral blocks and supplement feeds as a nitrogen enhancer.
- Improves formulation flexibility and cost-effectiveness in livestock nutrition strategies.
Key Advantages
High Nitrogen Content & Controlled Biuret
- ≥ 46 % nitrogen ensures high NPN efficiency.
- Low biuret levels help ensure safe application in ruminant diets when properly formulated.
Excellent Mixing & Solubility
- Uniform prills dissolve quickly and distribute evenly in feed blends.
- Reduces segregation during storage, transport, and processing.
Improved Feed Efficiency
- Supports rumen microbial growth, contributing to better fiber digestion, nutrient utilization, milk yield, and weight gain.
Consistent Quality & Feed Compliance
- Manufactured under controlled production systems with full batch traceability.
- Supplied with COA to support regulatory compliance and customer audits.
Packaging, Transport & Storage
- Packaging: 25 kg or 50 kg bags, 500–1000 kg jumbo bags, or bulk shipment.
- Storage: Cool, dry, ventilated warehouse; protect from moisture to prevent caking.
- Handling: Non-hazardous but hygroscopic; avoid prolonged moisture exposure.
