[0050] Example
[0051] Step 1. Establishment of breeding base group
[0052] The adult white king pigeon breeders are selected as the breeding base group (generation 0), and the base group breeds more than 1,000 pairs. The breeding pigeons are caged and numbered.
[0053] Step 2: Propagating the basic group to obtain G1 generation
[0054] The breeding pigeons of the basic group were bred continuously and obtained the G1 generation. It is hatched and nurtured by breeding pigeons.
[0055] Step 3. Raising of reserve breeders of G1 generation
[0056] When the squad pigeons are 25 days old, the individuals who are obviously underweight are eliminated, and the individuals who keep the breed wear an ankle ring with a unique number as individual identification. While wearing the ankle ring, 0.2ml of blood was taken from the wing root vein, anticoagulated and cryopreserved for later use. After the squad pigeon wears the ankle ring, it is transferred to the young pigeon loft to be raised a...
