What do field mice eat in captivity? - briefly
In captivity, field mice receive a diet of high‑quality rodent pellets enriched with seeds, grains, and occasional fresh greens or insects. Water should be available at all times, and supplemental treats must be limited to prevent obesity.
What do field mice eat in captivity? - in detail
Captive field mice require a diet that replicates the nutritional profile of wild foraging. Protein should constitute 14–20 % of the dry matter, supplied by high‑quality rodent pellets or laboratory chow formulated for small omnivores. Fat content must remain below 8 % to prevent obesity, while fiber levels of 5–7 % support gastrointestinal motility. Constant access to fresh water is essential; automated dispensers reduce contamination risk.
Supplementary items enhance dietary variety and encourage natural foraging behavior. Recommended categories include:
- Whole grains such as wheat, oats, and barley, provided in small quantities.
- Seeds (sunflower, millet) and nuts (unsalted peanuts, almonds) for additional fat and protein.
- Live or freeze‑dried invertebrates (crickets, mealworms) to supply essential amino acids and chitin.
- Fresh vegetables (carrots, broccoli, kale) offering vitamins, minerals, and moisture.
- Limited fruit pieces (apple, berries) for natural sugars and antioxidants.
Portion sizes should be adjusted to maintain a body condition score within the optimal range for the species. A typical adult consumes 3–5 g of dry feed per day, supplemented with 1–2 g of fresh items. Monitoring body weight weekly and inspecting fecal consistency helps detect dietary imbalances early.
Health considerations dictate the exclusion of toxic or high‑sugar foods. Avocado, chocolate, caffeine, and processed human snacks must be avoided. Excessive fatty seeds can lead to hepatic lipidosis, while over‑reliance on fruit may cause dental wear. Regular cleaning of feeding trays prevents mold growth and bacterial contamination.
Implementing a structured feeding regimen, combining nutritionally balanced pellets with diverse natural foods, sustains physiological health, promotes normal activity patterns, and reduces stress in captive environments.
