Rabbit farming is a profitable venture due to rabbits’ rapid reproduction, efficient feed conversion, and high demand for lean meat. However, to maximize profitability, farmers must determine the optimal slaughter weight—balancing growth rate, feed efficiency, meat yield, and market preferences.
The factors influencing the optimal slaughter weight for rabbits, including:
- Growth Patterns and Feed Efficiency
- Meat Yield and Carcass Quality
- Market Demand and Pricing
- Economic Considerations (Feed Costs vs. Revenue)
- Breed-Specific Variations
By analyzing these factors, farmers can make informed decisions to enhance profitability.

1. Growth Patterns and Feed Efficiency
1.1 Growth Rate of Rabbits
Rabbits grow rapidly in their first weeks, with growth rates slowing as they approach maturity. Typically:
- Weaning (4-5 weeks): 500–600 g
- 8-10 weeks: 1.8–2.2 kg
- 12 weeks: 2.5–3.0 kg
The feed conversion ratio (FCR) is most efficient between 8-12 weeks, meaning rabbits gain weight faster with less feed during this period.
1.2 Feed Conversion Ratio (FCR) and Optimal Weight
- FCR (5-8 weeks): 2.5–3.0 (kg feed per kg weight gain)
- FCR (8-12 weeks): 3.0–4.0 (less efficient as growth slows)
Key Insight:
Slaughtering rabbits at 10-12 weeks (2.2–2.5 kg live weight) maximizes feed efficiency before diminishing returns set in.
2. Meat Yield and Carcass Quality
2.1 Dressing Percentage
- Dressing percentage (carcass weight relative to live weight) is typically 50-60% for rabbits.
- Heavier rabbits (over 3 kg) may have higher fat deposition, reducing lean meat yield.
2.2 Optimal Slaughter Weight for Meat Quality
- 2.0–2.5 kg live weight: Best balance of lean meat and tenderness.
- Above 3.0 kg: Increased fat, lower market preference in many regions.
Recommendation:
Aim for 2.2–2.5 kg live weight for optimal meat yield and quality.
3. Market Demand and Pricing
3.1 Consumer Preferences
- Europe & High-Income Markets: Prefer rabbits at 2.0–2.5 kg (lean, tender meat).
- Developing Markets: May accept larger rabbits (up to 3.0 kg) for family consumption.
- Restaurants & Processors: Often prefer standardized weights (2.0–2.5 kg).
3.2 Price per Kilogram Trends
- Smaller rabbits (1.8–2.2 kg) may fetch a premium price due to higher demand.
- Oversized rabbits (>3 kg) may sell at a discount due to excess fat.
Key Takeaway:
Align slaughter weight with local market preferences to maximize revenue.
4. Economic Considerations
4.1 Feed Costs vs. Revenue
- Early Slaughter (8-10 weeks): Lower feed costs but smaller carcass.
- Late Slaughter (12+ weeks): Higher feed costs, diminishing returns.
Break-Even Analysis Example:
| Slaughter Age | Live Weight (kg) | Feed Cost (USD) | Selling Price (USD/kg) | Profit (USD) |
|---|---|---|---|---|
| 8 weeks | 1.8 | 4.50 | 5.00 | 4.50 |
| 10 weeks | 2.3 | 6.00 | 5.00 | 5.50 |
| 12 weeks | 2.8 | 8.00 | 4.80 | 5.44 |
Optimal Point: 10 weeks (~2.3 kg) provides the best profit margin.
4.2 Space and Labor Efficiency
- Faster turnover (8-10 weeks) allows more batches per year.
- Larger rabbits require more housing space and time.
Recommendation:
For maximum profitability, slaughter at 10-11 weeks (2.2–2.5 kg).
5. Breed-Specific Variations
Different breeds have varying growth rates and ideal slaughter weights:
| Breed | Optimal Slaughter Weight (kg) | Age (Weeks) | Key Traits |
|---|---|---|---|
| New Zealand White | 2.2–2.5 | 10–12 | High meat yield |
| Californian | 2.0–2.4 | 9–11 | Fast growth |
| Flemish Giant | 3.0–4.0 | 14–16 | Large but less efficient |
| Chinchilla | 2.0–2.3 | 9–11 | Good feed conversion |
Best for Profit: New Zealand White & Californian at 2.2–2.5 kg.
Here are ten frequently asked questions (FAQs) about rabbits:
1. What do rabbits eat?
Rabbits primarily eat hay (like timothy or orchard grass), fresh leafy greens, and a small amount of pellets. Avoid sugary or starchy foods.
2. How long do rabbits live?
Domestic rabbits typically live 8–12 years, depending on breed, diet, and care.
3. Do rabbits need vaccinations?
Yes, depending on location. Common vaccines protect against myxomatosis and rabbit hemorrhagic disease (RHDV).
4. Can rabbits be litter-trained?
Yes! Many rabbits can be trained to use a litter box, especially if spayed/neutered.
5. Do rabbits need companionship?
Rabbits are social and often thrive with a bonded partner. However, introductions should be gradual.
6. Why should I spay/neuter my rabbit?
It prevents health issues (e.g., uterine cancer in females), reduces aggression, and helps with litter training.
7. How much space does a rabbit need?
They need a large enclosure (at least 4x their stretched-out size) and daily free-roam time for exercise.
8. Why does my rabbit chew everything?
Chewing keeps their teeth trimmed (they grow continuously!). Provide safe chew toys to protect furniture.
9. Are rabbits good pets for children?
Rabbits are fragile and easily stressed; they’re better suited to calm, supervised households.
