Embodiment 1
[0046] The present invention is a method for improving the laying rate of Guizhou local chicken breeds by adopting the recessive white feather new strain bred by the above method, the implementation steps of the method can be found in figure 2 ,which is:
[0047] (1) F 1 Breeding of generation chickens: Recessive white feather chickens are selected as the male parent, which is characterized by stable genetic performance, obvious breed characteristics, neat appearance, good growth performance, and a 7-month-old rooster weighing 1.2 Kg.
[0048] Medium-sized high-yield laying hens are used as female parents (generally produce brown-shell eggs), which are characterized by relatively pure genetic foundation and good egg production performance. At 72 weeks old, the egg production can reach more than 270 eggs, and the average egg weight is more than 55 g.
[0049] Using artificial insemination technology, the above-mentioned parents were paired with two lines to pr...
Embodiment 2
[0055] The present invention is a method for improving the meat quality and flavor of foreign chicken breeds by adopting the new recessive white feather strain bred by the above method, and the implementation steps of the method can be found in image 3 ,which is:
[0056] (1) Recessive white-feathered chickens are selected as the male parent, which is characterized by stable genetic performance, obvious breed characteristics, neat appearance, good growth performance, and a 7-month-old rooster with a weight of 1.2 Kg.
[0057] The fast-growing broiler chicken is used as the female parent, which is characterized by a relatively pure genetic basis and a fast growth rate, but the meat quality is poor and the taste is rough.
[0058] (2) Using artificial insemination technology, the above-mentioned parents were paired with the second line to produce F 1 Substitute chicken.
[0059] bred F 1 The generation chicken contains 50% of recessive white feather chick...
