How much meat puree can be given to a rat? - briefly

A rat may be offered roughly 1 g of meat puree per 100 g of its body weight daily; for an average 250 g adult this equals about 2–3 g per day. This amount provides sufficient protein without exceeding the animal’s caloric requirements.

How much meat puree can be given to a rat? - in detail

A typical adult laboratory rat (weighing 250–300 g) can tolerate a daily intake of 10–15 g of meat puree when it is offered as a supplement to a standard laboratory diet. This amount provides roughly 50–70 kcal, representing 5–7 % of the rat’s total daily energy requirement.

The following factors influence the precise volume:

  • Body weight – Adjust the quantity proportionally; a 150‑g juvenile requires about 6–9 g, while a 350‑g adult may accept up to 18 g.
  • Nutrient composition – Pureed meat supplies protein (≈20 % w/w) and fat (≈10 % w/w). Excessive fat can lead to obesity; keep the puree’s contribution to total dietary fat below 10 % of the overall diet.
  • Feeding schedule – Offer the puree in two divided portions (morning and evening) to avoid rapid gastric distension.
  • Texture and temperature – Provide a smooth, room‑temperature puree to ensure easy ingestion and prevent chilling of the gastrointestinal tract.

Safety guidelines:

  • Use fresh, lean meat (e.g., chicken breast or turkey) free of bones, skin, and visible fat.
  • Store the puree at 4 °C and discard any leftovers after 12 hours to prevent bacterial growth.
  • Observe the rat for signs of regurgitation, diarrhea, or reduced activity; reduce the amount if adverse reactions appear.

In experimental protocols, record the exact weight of each portion and monitor body weight weekly to confirm that the supplemental puree does not disrupt normal growth curves. Adjust the volume as needed to maintain a stable weight trajectory.
