This blog contains excerpts from my column, ‘The Holistic Parrot’, that appears in the April 2011, #159 issue of Parrots magazine.
** Information update, since this blog was originally written and posted I have created a ‘Balanced Exotic Avian Food Plan’. When feeding the foods in this plan avian vitamin supplements are completely unnecessary, and can actually be harmful for your birds. Keep reading to learn more.**
Lack of Balance
Malnutrition is caused by an imbalance of nutrients – deficiencies or excesses. When creating diet and nutritional plans for parrots it’s essential to ensure a balance of nutrients is provided. Providing parrots and finches balanced nutrition is more important than the other companion animals I have worked with.
Caution: Fat Soluble Vitamins
In order to prevent vitamin toxicity in your birds you must monitor levels of vitamins A, D3 and C in your bird’s diet that are in formulated pellet diets and supplements. Vitamins A and D3 are fat-soluble vitamins. They are dispersed and stored in fat, any excesses remain in the body and can cause toxicity problems (hypervitaminosis).

Use caution when using vitamin and mineral supplements that contain these nutrients educate yourself – read the label, determine ingredients and their amounts, do the math, identify the amount of vitamin A, D3, C your bird will be receiving. If this information is not on the label contact the manufacturer.

Clearly, more research in avian nutrition is needed.

Remember, the companies that make the pelleted bird diets also establish these dietary allowances.
