Jeju Black Pig Farming & Quality Standards

Tamrain ensures strict quality control from farm to table by working closely with trusted farmers who follow rigorous management standards.

Pig Farming Schedule & Size Requirements

Weaning weight (25 days): ~5 kg
Shipping age: ~200 days
Live weight: 105–110 kg
Carcass weight: ~78 kg

Unlike commercial pig breeds, Jeju Black Pigs have unique characteristics, including smaller litter sizes, slower growth rates, and thicker back fat. To maintain optimal pork quality, Tamrain implements a structured farm management system. As part of our expansion efforts, we are addressing facility shortages and planning the construction of a new pig barn.

Feeding Process & Nutritional Approach

Jeju Black Pigs are raised under a specialized feeding program to ensure superior meat quality.

Their diet is similar to that of standard pigs but adjusted for their unique growth patterns.
After 150 days, high-protein, high-calorie feed can cause excessive back fat thickness, so a controlled, lower-grade finishing feed is used to maintain the ideal fat-to-meat ratio.

Commitment to
Sustainability & Ethical
Farming

Natural Mating & Genetic Purity

While most Jeju Black Pig farms rely on artificial insemination for efficiency, Tamrain recognizes the importance of preserving native genetic traits.
Moving forward, we aim to enhance crossbreeding programs with native Jeju Black Pigs, ensuring distinctive meat quality that differentiates Jeju Black Pork from other breeds.

Environmental Responsibility

We are actively working to reduce odor, improve pig barn conditions, and promote sustainable farming practices to coexist harmoniously with local communities.
By investing in eco-friendly solutions, Tamrain strives to produce the highest-quality Jeju Black Pork while fostering a responsible and sustainable pig farming industry.

Advanced Butchering Techniques for Ethical Processing

Tamrain ensures humane and ethical butchering by outsourcing to specialized slaughterhouses that follow high industry standards. These facilities use CO₂ stunning to minimize stress for pigs before processing.

CO₂ Stunning System

Uses the Somnia 408 CO₂ Stunning System, a globally recognized humane method.
Process:
- Pigs are exposed to controlled CO₂ gas, making them unconscious before slaughter.
- Reduces stress, noise, and movement, improving animal welfare and meat quality.
Benefits:
- Prevents poor-quality (PSE) meat.
- Safer for workers, as pigs remain calm.
- Less blood discoloration, keeping the meat clean and appealing.

Automated Processing & Hygiene

After stunning, automated systems handle bleeding, dehairing, and cleaning, reducing contamination.
Steam-based dehairing:
- Prevents water contamination.
- Ensures high hygiene without chemicals.
Final steps:
- Flame treatment and washing remove any remaining hair and sterilize the carcass.

Outsourcing Benefits

Since Tamrain does not own the butchering facility, outsourcing provides key advantages:

Cost Savings – No need for high capital investment in slaughterhouse operations.
High Standards – Partnering with specialized facilities ensures strict hygiene and humane practices.
Scalability & Flexibility – Tamrain can adjust production levels based on demand.
Focus on Core Business – Instead of managing a slaughterhouse, Tamrain can focus on branding, sales, and market expansion.

By outsourcing, Tamrain maintains consistent quality, humane slaughtering, and operational efficiency, ensuring premium pork production.

Additional details about the butchering facility

Comparison with European/Spanish Butchering Standards

European and Spanish butchering processes follow strict EU Animal Welfare Regulations and incorporate traditional methods, especially in Iberian pork production. Compared to these standards, Jeju’s process is more automated and industrialized, ensuring efficiency and consistency.

Stunning & Pre-Slaughter Handling

Both Jeju and European/Spanish facilities commonly use CO₂ stunning to minimize stress before slaughter. However, Jeju’s process is fully automated, reducing human error, while Iberian pork farms often rely on traditional handling methods with less automation. Bleeding is immediate and automated in Jeju, while smaller Spanish farms may still use manual bleeding methods.

Dehairing & Cleaning

Jeju’s facility uses steam-based dehairing with automated paddles, which is more hygienic and cost-efficient than the hot water scalding and mechanical scraping commonly used in Spain. Both systems use fire-singeing to remove fine hairs, but Jeju’s automated whip-wash system provides an extra level of cleanliness, reducing contamination risks.

Chilling & Meat Preservation

Jeju relies on rapid chilling (0°C to -5°C) to preserve meat quality. In contrast, Spanish facilities—especially those handling Iberian pork—favor dry aging, which enhances flavor and texture naturally. Jeju’s tubular rail system allows for large-scale storage, while Spanish farms often use traditional rail hanging or refrigerated storage methods.

Jeju’s butchering process is highly automated, ensuring efficiency, hygiene, and consistency in meat processing.
