Health Benefits for Guinea Pigs

The vitamin C content is the main reason for feeding oranges to your guinea pig, so we’ll focus on the health benefits of that vital nutrient.

Vitamin C has multiple key roles in the body.

  • It helps in the absorption of Iron from the gut, preventing Iron deficiency anemia
  • It increases immunity (Our natural ability to fight germs)
  • It has a protective action on cells from oxidative damage.
  • It stimulates the production of Collagen, which is a kind of protein that facilitates wound healing and also leads to firm and younger-looking skin.
  • It reduces the free radicals in our body which could lead to cancer.
  • It slows down the process of macular degeneration which is a common cause of vision loss in old age.
  • It has a role in lowering the levels of Cortisol (Stress hormone) in the body.

Oranges also have the following nutrients that make them a highly beneficial dietary item. Let’s take a look and see how these other nutrients benefit our piggies.

Oranges have a high calcium content, which keeps your cavy’s bones and teeth strong.


100 grams of orange has 30 ug Folate, which is especially important for young guinea pigs. It plays a significant role in healthy bone and bone marrow development.

Caution to Take While Feeding Oranges to Guinea Pigs

  • Introduce the fruit very gradually into the pet’s diet. Initially, offer a very small quantity and wait for a day or two while keeping a close eye on it for any side effects.
  • If your pet does well, you can slowly build up the quantity of the fruit without exceeding the amount recommended above.
  • If the fruit is not organic and is purchased from the market, be very vigilant while washing the fruit prior to serving them to the piggie to remove any pesticides that might be present on it.

  • Remove all seeds of the fruit before feeding it as the pet might choke on them.
  • Make that the fruit is ripe, as the pH of an unripe orange is acidic.
