In today’s increasingly competitive livestock and poultry industry, achieving cost reduction and efficiency gains through scientifically formulated diets has become a central concern for every producer. As a groundbreaking product in the non‑protein nitrogen feed sector, **slow‑release urea**, with its precise nitrogen‑release control technology, is delivering a revolutionary solution to ruminant nutrition and emerging as an “invisible profit driver” that boosts farming profitability.

### I. Addressing the Pain Points of Traditional Urea Applications and Ushering in a New Era of Safety and Efficiency
Traditional urea in ruminant diets suffers from three major drawbacks: **excessively rapid ammonia release, resulting in a utilization rate of less than 30%**; a strong ammonia odor that compromises palatability; and excessive intake, which can lead to ruminal toxicity. Slow-release urea employs physical encapsulation or chemical modification to create an intelligent controlled-release system: once the feed enters the rumen, the coating material degrades gradually under microbial action, ensuring that nitrogen is released at a rate perfectly synchronized with the pace of microbial synthesis of microbial protein. Experimental data show that high‑quality slow-release urea products can achieve precise control, with a 24‑hour release rate of ≤5% and a cumulative release over 28 days of ≤75%, thereby boosting nitrogen utilization to over 65%—2 to 3 times higher than that of conventional urea.

### II. Four Core Technological Advantages Reshaping the Feed Value Chain
1. **Intelligent Controlled-Release Technology**
A polymer–biochar double-layer coating process is employed, with an inner polyethylene glycol/starch composite film regulating the urea release rate and an outer biochar-based material serving as a physical barrier. Scanning electron microscopy reveals a coating thickness of 152 μm, enabling **43-day sustained release** at an average daily release rate of only 1.865%, which precisely matches the metabolic cycle of rumen microorganisms in beef cattle.

2. **Revolutionary Improvement in Palatability**
By employing an extrusion‑gelatinization process, urea is thoroughly integrated with corn starch, effectively eliminating the ammonia‑alkali odor. In a comparative trial conducted at a 10,000‑head cattle farm in Inner Mongolia, Shandong Anyi Bio’s extruded slow‑release urea product increased daily feed intake by 12% and reduced feed wastage by 8 percentage points.

3. **Toxicity Risk Prevention and Control System**
Adhering strictly to the “1% of dry matter in the diet” golden rule and implementing a stepwise adaptation protocol—starting with an inclusion rate of 0.3% during the first week, increasing by 0.1% each subsequent week—data from a large-scale dairy farm in Hebei show that, following the use of slow-release urea, mortality due to ammonia toxicity dropped from 1.2% to 0.03%, resulting in annual savings of over RMB 200,000 in veterinary costs.

4. **Significant Improvement in Economic Benefits**
Each kilogram of slow-release urea can replace 2.6–2.8 kg of protein feed; based on current soybean meal prices, this reduces the daily feed cost per finishing beef cattle by 1.8–2.5 yuan. A case study from a beef cattle cooperative in Xinjiang shows that full‑cycle use of slow-release urea lowered the share of feed costs from 58% to 49%, shortened the marketing cycle by 15 days, and increased per‑head profit by 420 yuan.

### III. Scientific Application Plan to Unlock the Full Value of the Product
1. **Precise Proportion Addition**
- Adult cattle: 1% of the diet’s dry matter, or 0.02%–0.05% of body weight
- Young cattle: should not exceed 1.5% of the concentrate supplement.
- Calves: Contraindicated before 6 months of age; during the transition period, it should be used in conjunction with a probiotic preparation.

2. **Tiered Adaptation Plan**
During the first week, limit the addition to 30% of the recommended level, then increase by 20% each subsequent week, while using adsorbents such as montmorillonite powder to mitigate peak ammonia release. It is also advisable to supplement with a rumen buffer (e.g., sodium bicarbonate) to maintain the rumen pH within the optimal range of 6.2–6.8.

3. **Key Points for Quality Assessment**
High-quality controlled-release urea should meet the following specifications: uniform particle size (2.00–4.75 mm), coating integrity rate ≥ 95%, 24-hour dissolution rate ≤ 5%, and biuret content < 0.5%. When purchasing, verify the manufacturer’s Feed Additive Production License and third-party test reports.

### IV. Industry Application Prospects and Trends
With the full implementation of the “antibiotic ban” and the continued rise in feed costs, slow-release urea is experiencing explosive growth. According to forecasts from the Feed Industry Center of the Ministry of Agriculture and Rural Affairs, China’s slow-release urea market is expected to exceed RMB 3.5 billion by 2028, with an annual compound growth rate of 18.7%. In particular, in beef and dairy cattle farming, its strategic value as a “protein feed alternative” is becoming increasingly evident.

As a professional feed supplier, we recommend that farms and farmers: **immediately launch a trial to replace conventional urea with slow-release urea**, conducting a 30-day comparative study to monitor key performance indicators such as feed intake, average daily gain, and feed-to-meat ratio. We are now offering a “first-order free trial plus on-site technical support” service to help you effortlessly achieve your transformation goals—reducing feed costs by 15% and boosting farming profitability by 20%.
