A matching breeding method for white laying hens with crested five-claw powdered shank

Abstract

The invention discloses a mating breeding method for crested claw pink shin corollule white laying hen (gallus domesticus). The method includes the detailed steps that S1, fast-feathering dominant white-feather leghorns (L series) are selected and bred; S2, fast-feathering series (K series) princess chickens and slow-feathering (M series) princess chickens are selected and bred to serve as first male parents and first female parents, and F1 generations are generated through hybridizing; S3, with homozygous hemp feather series (W series) Wenchang chickens in S1 being male parents and F1 generation hens generated in S2 being female parents, hybridizing is performed, and F2 generation cocks and hens obtained through hybridizing are characterized in that feathering is fast, feather is white (individual black speckles exist in a small number of chickens), heads are crested, claws are formed, skin is white, shins are pink, combs are in a cronollule type, eggshells are white, the yield of laid eggs is high, egg weight is small, the number of eggs laid by hens of 43 weeks old and the number of eggs laid by hens of 72 weeks old are 113 and 217 respectively, the weight of the hens of 43 weeks old and the weight of the hens of 72 weeks old are 1160 g and 1289 g respectively, the weight of the eggs of the hens of 43 weeks old and the weight of the eggs of the hens of 72 weeks old are 43.2g and 46.52 g respectively, feed conversion is 2.56:1, and market competitiveness is high.
