Introduction to Mixed Feeding
Mixed feeding combines hay, pellets, and fresh supplements to provide a balanced diet for small herbivores like rabbits, guinea pigs, and chinchillas. This approach mimics natural grazing and ensures essential nutrients. Below, we break down each component and how to integrate them effectively.
Recommended Diet Types
Hay (Primary Food)
Hay should make up 80% of the diet. Timothy hay is ideal for adults; alfalfa is for growing or lactating animals due to higher calcium and protein. Grass hays like orchard or meadow are also good.
Pellets (Supplemental)
High-quality, plain pellets (no seeds, nuts, or colored bits) provide concentrated nutrients. Feed in measured amounts to prevent obesity.
Fresh Supplements
Leafy greens (e.g., romaine, kale, cilantro) and small amounts of vegetables (carrot, bell pepper) add variety and vitamins. Fruits are occasional treats due to sugar.
Portion Sizes by Age, Size, and Activity
| Pet Type | Hay (unlimited) | Pellets per day | Fresh Supplements | Daily Calories |
|---|---|---|---|---|
| Adult rabbit (2-4 kg) | Unlimited | 1/4 cup | 2 cups greens | ~300-400 kcal |
| Guinea pig (0.7-1.2 kg) | Unlimited | 1/8 cup | 1 cup greens + Vitamin C source | ~200-300 kcal |
| Chinchilla (0.4-0.8 kg) | Unlimited | 1-2 tablespoons | Small pieces of dried herbs | ~150-250 kcal |
Feeding Frequency and Schedule
Provide fresh hay at all times. Offer pellets once or twice daily. Fresh supplements should be given in the morning or evening. Remove uneaten fresh food after a few hours to prevent spoilage.
Essential Nutrients
Protein: 12-16% for adults, higher for young. Fat: 2-4%. Fiber: Critical – 18-25% from hay. Carbohydrates: From hay and greens. Vitamins: A, D, E, K, B complex. Minerals: Calcium, phosphorus (ratio 2:1), magnesium. Guinea pigs need added Vitamin C (10-30 mg/kg daily).
Toxic or Harmful Foods
- Iceberg lettuce (low nutrients, can cause diarrhea)
- Bread, pasta, grains (high starch, harmful to gut flora)
- Chocolate, caffeine, alcohol (toxic)
- Onions, garlic, leeks (damage red blood cells)
- Rhubarb, avocado (poisonous)
Water Intake
Fresh, clean water should be available 24/7. For rabbits and guinea pigs, use a sipper bottle or bowl. Expect 50-100 ml per kg per day. Monitor intake; changes may indicate illness.
Beneficial Supplements
Probiotics (e.g., Bene-Bac) after antibiotics or stress. Vitamin C for guinea pigs if diet insufficient. Oxbow Natural Science supplements for joint or urinary support. Always consult a vet before adding supplements.
Differences by Life Stage
Young (under 6 months)
Feed alfalfa hay for growth; unlimited pellets (e.g., 20% protein). Introduce greens gradually after 3 months.
Adult (6 months to 5 years)
Switch to timothy hay; limited pellets to prevent obesity. Maintain fresh greens.
Senior (5+ years)
Monitor weight and dental health. Softer hay or pellets if teeth are worn. Increased water intake; joint supplements may help.
Signs of Healthy vs. Poor Diet
Healthy: Regular, well-formed droppings; shiny coat; active behavior; normal appetite. Poor: Soft or misshapen stool, weight loss or gain, overgrown teeth, lack of energy, or decreased appetite. Immediate vet check if symptoms persist.
