Undersized white feather broiler breeding method

Abstract

The invention discloses an undersized white feather broiler breeding method. An undersized yellow chicken and a white feather broiler are used for being in reciprocal cross and after that the yellow chicken and the white feather broiler are in horizontal cross fixing. Then, shutting breeding can be proceeded to breed a breed of undersized white feather broilers. The undersized white feather broiler breeding method is used for breaking through a traditional thought that a large-sized cock is mated with a large-sized hen to give birth to a parents-generation white chicken in a normal bodily form in the prior art. An undersized cock is chosen to mate the large-sized hen to give birth to the parents-generation white chicken in a grain-saving type. A method that an undersized yellow chicken (contains a dw gene) is half-bred with a white fast-growing chicken is used for choosing and breeding a breed of dominance undersized white chickens. High isozygoty and high stability of the dw gene can be guaranteed, and absolute security of resource can be guaranteed. An adult chicken is shapely in body and gesture, rounded in bodily form, huge in head, thick in neck, compact and shining in feathers and strong and muscular in chest-leg muscles. Chicken herd is good in uniformity and strong in disease resistance. Hens which enter into pheasantries for 66 weeks can lay 170-175 eggs. The weight of each egg is 50-60 grams. Passing percent of hatching egg is more than 95%. Emergence rate of hatching is 90%.

Description

technical field [0001] The invention relates to poultry breeding technology, in particular to a method for breeding dwarf white-feathered broilers. Background technique [0002] At present, the matching mode of fast-growing white-feathered broilers in the chicken industry is: large-sized roosters paired with large-sized hens. The disadvantage of this mode is that it takes up a lot of space, consumes a lot of materials, the overall cost of feeding is high, and the risk is high. [0003] Moreover, the existing raw material prices and labor costs continue to rise, resources such as land and food are increasingly scarce, the epidemic situation of chicken farming is becoming more and more complicated, and competition is becoming increasingly fierce. To survive in the industry market competition, technological innovation is imperative. Contents of the invention [0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to prov...
