Rabbit Feed Pellet Mill with Die 3mm: Complete Selection Guide
News 2026-07-30
Page SEO Summary: This technical guide helps rabbit farmers and feed producers evaluate rabbit feed pellet mills with 3mm dies—covering equipment types, capacity selection, investment considerations, and the special requirements for rabbit feed production.
Rabbit farming is growing worldwide as a sustainable source of meat and fur. Rabbits require feed that is high in fiber, with specific nutritional profiles for different life stages. Pelleted feed is ideal for rabbits—it reduces waste, improves feed efficiency, and ensures consistent nutrition.
A rabbit feed pellet mill with a 3mm die produces pellets of the optimal size for rabbits. This size is suitable for growers, adult rabbits, and even weaners, making it the most versatile die size for rabbit feed production.
This guide provides a comprehensive technical framework for understanding, selecting, and procuring rabbit feed pellet mills with 3mm dies.
Why 3mm Pellets for Rabbits?
The Importance of Pellet Size
| Aspect | Impact |
|---|---|
| Palatability | Right size for rabbit mouths |
| Nutrition intake | Consistent consumption |
| Feed efficiency | Better FCR |
| Waste reduction | Less breakage and waste |
Pellet Size by Rabbit Stage
| Rabbit Stage | Pellet Diameter | Why |
|---|---|---|
| Weaner (1-2 months) | 2-3 mm | Small mouth; easy chewing |
| Grower (2-4 months) | 3-4 mm | Fast growth; high intake |
| Adult/Doe | 3-4 mm | Consistent nutrition |
| Breeding buck | 3-4 mm | Maintenance |
The 3mm Advantage: A 3mm die produces pellets suitable for all rabbit stages, making it the most versatile choice for rabbit feed production.

Frequently Asked Questions
1. Why choose a 3mm die for rabbit feed?
A 3mm die produces pellets suitable for all rabbit stages—weaners, growers, adults, and does. It is the most versatile die size for rabbit feed production.
2. What capacity do I need for my rabbits?
Use this formula: (rabbits × daily feed per rabbit) ÷ (operating hours). For 200 rabbits (average 0.12 kg/day × 8 hours), you need about 80-100 kg/h.
3. Is a 3mm die suitable for all rabbit ages?
Yes. Weaners eat 2-3mm pellets, and adults eat 3-4mm pellets. The 3mm size works for both, making it the ideal choice.
4. What is the difference between flat die and ring die?
Flat die is lower cost, suitable for 30-200 kg/h. Ring die is higher output, suitable for 200+ kg/h. For small to medium rabbit farms, flat die is sufficient.
5. How much does a rabbit feed pellet mill with 3mm die cost?
A flat die machine costs $800-3,000. A ring die machine costs $3,000-15,000. A complete line costs $3,000-80,000.
6. Is rabbit feed pelleting profitable?
Yes. On-farm feed production can save 15-25% compared to purchased feed. For a 200-rabbit operation, savings of $1,000-2,500 per year are typical.
7. What grinding fineness is needed?
Rabbit feed requires fine grinding (<1.5 mm) for digestibility and pellet quality. Use a hammer mill with a small screen (1.5-2.0 mm).
8. Do I need a conditioner?
A conditioner is recommended for better pellet quality. It adds steam and moisture, improving binding and durability. However, simple flat die machines may not include a conditioner.
