  • Pros: THE source for detailed nutritional data. Includes most foods commonly eaten by humans.
  • Cons: must look up each vegetable and fruit individually to find nutritional data.

Nutrient Requirements of Laboratory Animals, Fourth Revised Edition, 1995.

The National Academy of Sciences lists the Nutrient Requirements of the Guinea Pig .

  • Pros: a reference bringing together what is known about the nutritional requirements of guinea pigs.
  • Cons: some data is over 50 years old, other data is extrapolated from rat studies (the authors of this article encourage more research). Some of the specific diets recommended are only suitable for laboratory animals. The authors note the high protein, low fiber diet typical of a laboratory animal and mention that a guinea pig's diet in the wild consists of much more fiber and green vegetation.

A complete list of requirements is printed on page 104. Keep in mind, these are not daily requirements but instead the amounts of vitamins and minerals they recommend adding to a kilogram of food to provide proper nutrition. Your pig will only eat a fraction of a kilo per day.
