What can be fed to baby rats? - briefly
Newborn rats need a diet of high‑protein milk replacer or formula, transitioning to softened, protein‑rich kibble as they wean. Fresh water should be provided continuously.
What can be fed to baby rats? - in detail
Feeding neonatal rats requires a diet that meets high protein, fat, and moisture demands while mimicking the natural composition of mother’s milk. Commercially prepared rodent milk replacers are the most reliable option; they contain balanced nutrients, are sterile, and are formulated for easy digestion. When using a milk replacer, follow the manufacturer’s dilution instructions precisely and provide the mixture at body temperature (≈37 °C).
If a milk replacer is unavailable, a homemade formula can be prepared using the following components in the indicated proportions:
- Powdered goat’s milk or evaporated milk – 40 %
- Egg yolk (raw, separated from white) – 30 %
- Light corn syrup or glucose solution – 20 %
- Vitamin‑mineral supplement formulated for rodents – 10 %
Blend the ingredients thoroughly, warm to body temperature, and strain to remove any particulates. Sterilize all equipment before use.
Solid foods may be introduced after the pups reach 10–12 days of age, once their incisors begin to appear. Suitable items include:
- Softened commercial rodent pellets (crushed and moistened)
- Cooked, unseasoned egg white
- Small pieces of boiled chicken breast, finely shredded
- Fresh, washed vegetables such as carrots or zucchini, finely grated and moistened
Introduce each new food item individually, observing the pups for any signs of digestive upset. Maintain constant access to clean, fresh water after the introduction of solids.
Feeding schedule should consist of 6–8 feedings per day for the first two weeks, gradually reducing to 3–4 feedings as the rats approach weaning at 21 days. Each feeding volume should be measured to provide approximately 10 ml of milk replacer per 10 g of body weight daily, adjusted according to growth rate.
Monitor weight gain daily; a healthy neonate should increase by 2–3 g per day. Any deviation from expected growth warrants immediate veterinary consultation.
