Is line breeding inbreed? Yes!
What is line breeding and what does it mean???
Well 99.9% of all breeders for show birds line breed.
All of the budgerigars outside of Australia have been line bred. How can I say this. Well 100 years ago Australia stopped exporting Budgerigars to the world. To supply budgerigars for sale, those with the stocks started to inbreed for the demand from the public.
During the second world war brittain was in short supply of food for the public let alone the seed for the birds. Many other europien countries were the same. Many birds were killed so that the few could survive. After the war the stocks had to be brought back. England couldn't get birds from Australia and were forced to inbreed but decide to have a very good look into how to go about it.
By selectively pairing the birds they found a way to strength and improve on the structure of the bird. right down to the health. Mean while in other parts of the world they were also looking down the same line. Germany was also inbreeding for improvement.
So how is it done. (Generally)
Cock X
Hen A .................... Hen B
1st year mating
Chicks .................... Chicks
Cock .... Hen ...................Cock .... Hen
Cock .... Hen ...................Cock .... Hen
Cock .... Hen ...................Cock .... Hen
Cock .... Hen ...................Cock .... Hen
2nd Year
Cocks from pairing of Cock x and Hen A are mated to Hens of pairing Cock X to Hen B
Hens from pairing of Cock x and Hen A are mated to Cocks of pairing Cock X to Hen B
(Half Brother to Half Sister)
3rd Year
Hens from the result ae breed back to Cock X
Grandfather to Grand Daughter.
This is assuming that Cock X has really great features to start with.
Chicks from the 1st year mating will have half his genes and half from the hen.
Chicks from the 2nd year mating will only have a quarter of his genes.
Chicks from the 3rd year will have 75% his genes. This mating was ment to strength the strain...his strain....his line.
Other Combinations are Uncle to Neice, Aunt to Nephew, Cousin to Cousin.
The idea is to enhanse the features of the bird. Features also being health and fertility. besides the looks.
There are not many that breed brother to sister but it does occur.
Many peole that conlony breed bird with have line breeding and in breeding happening in their aviaries unless they have very strick ways of stoping it.
This topic is in no way meant to promote line breeding but to explain how and why.
