Egg — a structure which the females of certain animal species lay as a means of reproduction, it contains a fertilized zygote and nutrition in the form of yolk for the developing offspring, sometimes contains other substances (e.g., the white of a henâ€™s egg), sometimes surrounded by a protective outer shell.
Animal reproductive body consisting of an ovum or embryo together with nutritive and protective envelopes; especially the thin-shelled reproductive body laid by e.g. female birds.
Oval reproductive body of a fowl (especially a hen) used as food. Otherwise known as the ovum. Otherwise, externally, an egg can be deposited by parents which soon develop into offspring. Some domesticated birds do not lay eggs.
East Indian history indicates that wild fowl were domesticated as early as 3200 B.C. Egyptian and Chinese records show that fowl were laying eggs for man in 1400 B.C. Europe has had domesticated hens since 600 B.C. There is some evidence of native fowl in the Americas before Columbusâ€™ arrival. However, it is believed that on his second trip in 1493, Columbusâ€™ ships carried to the New World the first of the chickens related to those now in egg production. These strains originated in Asia.
Most people of the world eat the egg of the chicken, Gallus domesticas. Nearly 200 breeds and varieties of chickens have been established worldwide. Only a few breeds are economically important as egg producers. Most laying hens in the U.S. are Single-Comb White Leghorns.
Eggs are all-natural and packed with a number of nutrients. One egg has 13 essential vitamins and minerals in varying amounts, high-quality protein, unsaturated fats and antioxidants, all for 70 calories.
Eggsâ€™ nutrients can help you with weight management, muscle strength, eye health, brain function and having a healthy pregnancy. Particularly important for aiding healthy brain function and pregnancy is choline (pronounced KOH-leen), which is amply present in eggs.
