Raising rabbits for meat requires a solid understanding of their growth patterns to optimize feeding, health, and harvest timing. Meat rabbit breeds, such as New Zealand Whites, Californians, and Flemish Giants, are selected for their rapid growth and efficient feed conversion. This guide provides a week-by-week breakdown of a meat rabbit’s growth, including weight expectations, feeding recommendations, and key developmental milestones.
Table of Contents
Week 1: Birth to 7 Days
Weight: 50–100 grams (varies by breed)
Newborn kits are entirely dependent on their mother (doe). They are born hairless, blind, and deaf.
Key Developments:
- Feeding: Only mother’s milk (colostrum in the first 24 hours is crucial for immunity).
- Behavior: Kits stay huddled for warmth; movement is minimal.
- Survival Check: Ensure all kits are nursing (full, round bellies indicate proper feeding).
Care Tips:
- Keep the nesting box clean and dry.
- Monitor doe’s milk supply—if kits appear weak, supplemental feeding may be needed.
Week 2: 8–14 Days
Weight: 150–250 grams
Kits begin developing fur and their ear canals open.
Key Developments:
- Eyes Open: Around 10–12 days.
- Movement: Start crawling but remain in the nest.
- Feeding: Still exclusively milk-fed.
Care Tips:
- Check for eye infections (common if bedding is dirty).
- Ensure the nest stays warm—avoid drafts.
Week 3: 15–21 Days
Weight: 250–400 grams
Kits become more active and start exploring outside the nest.
Key Developments:
- Weaning Prep: Begin nibbling on hay/pellets (though milk is still primary).
- Behavior: Playful hopping, social interaction with littermates.
Feeding Transition:
- Introduce alfalfa hay and starter pellets (18% protein).
- Fresh water should always be available in shallow dishes.
Care Tips:
- Watch for diarrhea (coccidiosis risk increases with solid food introduction).
Week 4: 22–28 Days
Weight: 400–600 grams
This is a critical week as kits start weaning.
Key Developments:
- Weaning Begins: Kits still nurse but eat more solids.
- Growth Spurt: Rapid muscle and bone development.
Feeding:
- High-protein pellets (16–18%).
- Unlimited alfalfa hay for fiber and calcium.
Care Tips:
- Separate kits from the doe for short periods to encourage solid food intake.
- Monitor weight—slow growers may need supplemental feeding.
Week 5: 29–35 Days
Weight: 600–900 grams
Kits are now fully weaned or close to it.
Key Developments:
- Independent Eating: No longer reliant on milk.
- Social Hierarchy: Dominant kits may eat more—ensure equal access to food.
Feeding:
- Continue high-protein pellets.
- Introduce small amounts of fresh greens (avoid sudden changes to prevent digestive upset).
Care Tips:
- Weigh kits weekly to track growth.
- Separate by size if competition for food is an issue.
Week 6: 36–42 Days
Weight: 900–1,200 grams
Growth rate peaks—this is when feed efficiency is highest.
Key Developments:
- Muscle Build-Up: Meat breeds gain ~50g/day.
- Behavior: Highly active, playful, and curious.
Feeding:
- Free-choice pellets (16% protein).
- Unlimited hay + limited greens (e.g., kale, carrot tops).
Care Tips:
- Watch for overgrown teeth (provide chew toys or wooden blocks).
Week 7: 43–49 Days
Weight: 1.2–1.6 kg
Most meat rabbits reach fryer weight (1.5–2 kg) by 8–10 weeks.
Key Developments:
- Slower Growth: Feed efficiency declines slightly.
- Sexual Maturity Signs: Bucks may start mounting.
Feeding:
- Reduce protein slightly (14–16%) if nearing harvest weight.
- Avoid obesity—measure pellets if weight gain is too rapid.
Care Tips:
- Separate males and females if keeping past 10 weeks.
Week 8: 50–56 Days
Weight: 1.6–2.2 kg
Ideal harvest time for fryers (young, tender meat).
Key Developments:
- Prime Meat Quality: Lean, mild flavor.
- Feed Conversion Ratio (FCR): ~3:1 (3 lbs feed per 1 lb weight gain).
Feeding:
- Maintain consistent pellet amount (~100g/day).
- Limit treats to prevent fat buildup.
Care Tips:
- Check for proper muscling before harvest.
Weeks 9–12: 57–84 Days
Weight: 2.2–3.5 kg
Reaches roaster size (older, slightly tougher meat).
Key Developments:
- Growth Slows: Requires more feed per pound gained.
- Fat Deposition: Excess fat can affect meat quality.
Feeding:
- Adjust to maintenance pellets (14% protein).
- Increase fiber (grass hay) to prevent obesity.
Care Tips:
- Harvest before 12 weeks for best meat yield.
Beyond 12 Weeks (Flemish Giants & Heavy Breeds)
Some large breeds (e.g., Flemish Giants) continue growing up to 6–9 months, reaching 5–7 kg.
Feeding Adjustments:
- Lower protein (12–14%) to prevent kidney strain.
- More forage-based diet (grass hay, limited pellets).
Harvest Recommendation:
- 5–6 months for optimal meat-to-bone ratio.
Growth Chart Summary Table
| Week | Avg. Weight (kg) | Key Milestones | Feeding Focus |
|---|---|---|---|
| 1 | 0.05–0.1 | Blind, deaf, milk-only | Mother’s milk |
| 2 | 0.15–0.25 | Eyes open, fur growth | Milk only |
| 3 | 0.25–0.4 | Starts nibbling solids | Introduce pellets & hay |
| 4 | 0.4–0.6 | Weaning begins | High-protein pellets (18%) |
| 5 | 0.6–0.9 | Fully weaned | Unlimited pellets + hay |
| 6 | 0.9–1.2 | Rapid muscle growth | Free-choice pellets |

Factors Affecting Growth Rate
- Genetics: Meat breeds grow faster than dwarfs or pets.
- Diet: High-protein feed accelerates growth.
- Health: Parasites or illness stunt growth.
- Environment: Stress (heat, overcrowding) slows development.
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.
