Feeding additional items

Whilst Harrison’s is scientifically formulated to be a nutritionally balanced diet it is recommended that owners also feed a limited amount of fruit and vegetables to their pet birds, however these additional food items should be limited to no more than 10% by volume of the overall diet. Controlling the intake is to ensure that your pet gets the majority of its food in a form which is balanced for energy, protein and essential minerals and vitamins.

Over-feeding of additional (energy rich but often micronutrient poor) items may result in a dilution and imbalance of these nutrients in the overall diet. It is important to carefully follow supplementation guidelines for Harrison's to be fully effective.

Because Harrison’s Diets are scientifically formulated it is not required nor recommended to supplement with vitamins, minerals or other bird or animal food products unless explicitly directed by your avian veterinarian.

When feeding fruit and vegetable where possible it is best to offer certified organic vegetables and fruits in small quantities; select dark yellow meaty or dark green leafy items such as sweet potatoes, carrots, pumpkin, winter squash, broccoli, parsley, spinach, mango or papaya. Try and avoid those high in sugars (such as grapes) as they provide energy but little else.

For birds with suspected iron-storage disease

There are many suggestions as to the contributory factors predisposing to Iron Storage Disease (ISD) in captive birds. Some species are known to be particularly affected but the condition has been recorded in a wide range of species including parrots. For those pet birds where ISD has been diagnosed or suspected there are some dietary considerations that should be followed.

Avoid grapes, currants, raisins, liver, red meat, egg yolk or dark green vegetables such as spinach, which may contain high levels of iron. Avoid citrus fruits, tomatoes, kiwi, strawberries and other foods containing vitamin C as this increases the absorption of iron from the diet.

The organic nature of the products used to manufacture Harrison’s means that there is natural variability in the levels of iron in the foods and whilst Harrison’s diets, are not designated ‘low iron’ diets (recommended at >70ppm) they are low in iron.
