Birds Pigeons Could Produce Milk it Rich Protein and Antioxidant

It turned out that not only the milk produced by mammals or mammals only. Some birds also produce milk from its craw. Craw is a small pouch in the esophagus of birds to store food before it is digested by the stomach. But not just any bird can produce a 'milk'.

Only a few species of birds such as pigeons, flamingos or the male emperor penguin who can produce 'milk' is spewed into the mouths of children. 'Milk' is a liquid produced from cells lining the cache and it is important for growth and development of young pigeons because it is rich in fat and protein.

Research published in the journal BMC Genomics shows that the 'milk' pigeon contains antioxidants and increase the immunity protein. Researchers from CSIRO Livestock Industries and Deakin University in Australia compared the gene profiles in four female pigeons 'feeding' and 4 female pigeons 'not-feeding'.

Dominant genes that exist in pigeons 'feeding' is a gene whose role is also to stimulate cell growth, producing an antioxidant and strengthens the immune system. Researchers also found genes related to the production of triglycerides are fats that suggests that fat in the 'milk' is derived from pigeon liver.

"It is possible that antioxidant and immune proteins are also contained in 'milk' pigeons. These substances directly enhance the immune system protects the body tissues pigeons and doves old," said study author, Meagan Gillespie as quoted from ScienceDaily,

This study gives a brief view of some process that occurs when the 'milk' in the pigeon craw has been formed.

"This mechanism is an interesting example of evolutionary systems to be compared with the milk of mammals, because the 'milk' pigeons have a function similar to mammalian milk,", if you are interested in trying to 'milk' pigeon?
