When pet bird owners go to their veterinarian or bird-savvy pet store, they are often informed that pellets or Nutri-Berries<\/a> are better than seeds as the major portion of the diet. But what is the difference really?<\/p>\n

Pellets, and other formulated diets<\/a> like Nutri-Berries, are created to have a balanced ratio of nutrients packed into a single unit. These formulations are based off research done in granivorous birds, including chickens, budgerigars, and cockatiels. We still need to learn a lot about pet parrot nutritional requirements, but pellets provide a much better balance of nutrients than seeds.<\/p>\n

Seed mixes that are typically found in pet bird diets are unbalanced in various nutrients. Both deficiencies and excesses occur when a bird is fed these as the main part or only component of their diet. Seeds can and do lead to many health problems if they are fed in inappropriate quantities and ratios in the diet.<\/p>\n

When comparing pellets and seeds on a nutrient level, researchers and avian veterinarians have identified several key differences. Following is a list of the unbalanced nutrients that occur in seed-based diets, how these nutrients are important for life, and the effects for a bird not having these nutrients adequately provided.<\/p>\n

Deficiencies Of A Seed-Only Diet<\/h3>\n

Calcium & Phosphorus<\/h4>\n

Nutri-Berries, pellets, and other formulated diets are created with the goal of offering balanced nutrition in every bite.<\/figcaption><\/figure>\n

Seeds are insufficient in calcium<\/a> and often have an imbalance in their calcium to phosphorus ratio. Calcium is one of the most commonly discussed minerals in birds, particularly because of its vital role in reproduction and egg laying. Calcium is required to form the shell of an egg; however, it is also required in the body for normal bone health, nervous system functioning, and muscle health. Deficiencies can result in egg binding, impaired bone development, thin eggshells, poor uterine contractions and neurologic signs like seizures.<\/p>\n

Phosphorus is a mineral that functions closely with calcium. The ratio of calcium to phosphorus is important and should be about 2 parts calcium to 1 part phosphorus. Seeds are often unbalanced with this ratio and have calcium in lower amounts and phosphorus in higher amounts. Deficiencies in phosphorus or imbalances in the calcium-to-phosphorus ratio can result in weakness, rickets, and thin-shelled eggs. Excessive amounts of phosphorus can interfere with the absorption of calcium from the intestinal tract and induce a condition known as nutritional secondary hyperparathyroidism. Although any pet bird can experience imbalances in these nutrients when fed a seed-based diet, African Grey<\/a> parrots are well-known for deficiencies in calcium , which can cause seizure activity and poor bone development in young individuals.<\/p>\n

Sodium<\/h4>\n

Sodium is an important element for cell signaling and electrical conductance. Seeds do not supply ample amounts of this, which can result in deficiencies that cause poor egg production and poor growth.<\/p>\n

Zinc<\/h4>\n

Zinc functions as a cofactor for many different enzymes and is important for growth, reproduction, and tissue healing. Low levels of zinc found in seeds can result in poor growth, thicker and shorter long bones, scaling of the feet and skin, and poor feathering.<\/p>\n

Iron<\/h4>\n

Iron\u2019s importance lies in the fact that it is involved in cellular respiration. It is complexed with the protein known as heme<\/a>, and it helps transport oxygen around the body to tissues. Diets that are exclusively seeds are low in this element, and deficiencies can lead to anemia.<\/p>\n

Lysine\/Methionine<\/h4>\n

These are both proteins and are just two of the approximately 20 amino acids that are necessary for life. Proteins have a wide variety of functions within the body. They act as enzymes to catalyze reactions. Both lysine and methionine have structural properties and make up portions of muscles and collagen. They act as transports of compounds both within and outside of cells. Both function in the bloodstream, both to help with the immune system and with clotting blood. Their list of functions can go on and on. Deficiencies in lysine and methionine are common with seed-based diets and have been associated with liver disease in birds.<\/p>\n

Vitamin A<\/h4>\n

Vitamin A is a fat-soluble vitamin that is important in vision, immune system health, and in cells that line the skin, respiratory tract, reproductive tract, kidneys, and glandular tissues. Deficiencies in this nutrient are very common for seed diets and can result in a change in the superficial epithelial cells of the previously mentioned tissue. This can then result in various problems, such as sinus infections, kidney disorders, and reduced fertility and hatchability of eggs.<\/p>\n

Vitamin B<\/h4>\n

There are several B vitamins, but there are just a few that seeds are often lacking.<\/p>\n
