Most Common Nutritional Deficiencies in Aviculture

Robert Black was the guest speaker at the February 25, 2005
meeting of Capitol City Bird Society in Sacramento, California.
Notes by Darrell Horst

 

• Protein

Protein deficiencies are common in finches, parrots and budgies. But not common in canaries. Why, because the canary breeder has found the problem and supplements the diet with additional protein.
The most complete protein is hard-boiled egg, boiled 12 minutes to maintain the rich yellow color of the yolk. Other sources include shelled sunflower seeds, soy protein and game bird starter, (not medicated). The game bird starter has 30% protein.
The 6 components of Robert Black's bird diet are; game bird starter, hard-boiled egg, shelled chopped sunflower seed, millet, crushed egg shells and Vionate, a vitamin-mineral supplement.
Robert raises about 2000 birds and rarely has a problem once his birds are established on this diet. He raises his birds outdoors in sometimes below zero weather without problems. Robert mentioned too that his decision to use the game bird starter was based on price and protein content. Most other bird pellets contain 10-15% protein and cost many times more than the game bird starter.

• Vitamin A

About 90% of parrots suffer from some sort of vitamin A deficiency. Good sources of vitamin A include; hard-boiled egg & Vionate, powdered A & D, and cod liver oil.

• Vitamin D3

The only form of vitamin D a bird can absorb is vitamin D3. Vitamin D3 allows the bird to absorb calcium. Good sources include; hard-boiled egg, fish oils such as cod liver oil and a powdered form of A & D by Nature’s Way.

 

• Linoleic Acid

Good sources are; safflower oil and any of the oily seeds such as flax, rape and sunflower.

• Calcium

Calcium is rarely deficient in foods, but is not always absorbed properly. Phosphorus and calcium need to be in balance. Crushed ground egg shell contains 90% calcium.

• Trace Minerals

- Zinc, male birds need zinc. Good sources of zinc are whole grains, sunflower seed. Lack of zinc can cause infertility problems.

- Iodine, Gouldian and other colored finches need extra iodine. Supplemental iodine can bring back lost head feathers.

- Manganese, good for nerves. Sources include whole grain seeds and Vionate vitamin/mineral supplement. Lack of manganese in the chicks diet can cause star gazing.


Robert mentioned several times that his goal was to find a healthy diet for his birds that was priced in a range that he could afford with over 2000 birds to raise. He gave many cases where his six ingredient diet turned many a deficient bird around. Robert is a big user of hard-boiled egg and since he mixes it with the game bird starter, it remains dry and does not spoil unless it becomes wet from a birds bath or rain. Robert feeds these six ingredients separately and offers them free choice daily. He rarely has a sick or deficient bird to deal with.
