Breeding method of low-speed type super-quality chicken commercial line general female parents

Abstract

The invention relates to the field of fowl breeding, in particular to the supporting technological field of low-speed type super-quality chickens, and discloses a breeding method of low-speed type super-quality chicken commercial line general female parents. The breeding method concretely includes the steps that an offspring bred from a French recessive white rock and a Ling mountain chai hen belonging to low-speed type super-quality chickens is subjected to weight fixing and feather color purification selection and then a F0-generation low-speed type recessive white feather broiler is generated in a crossing mode, chickens having no broodiness and a short production period are selected in the F1 generation, and chickens in the following generations are selected according to disease resistance and egg laying performance of the chickens based on a family selection method. The low-speed type super-quality chicken commercial line general female parents bred according to the method have the advantages of being good in egg laying performance, free of broodiness, high in disease resistance capacity, short in production period and capable of reserving the majority features of color feather parents and reducing the feeding amount of grandparent generation female parents; the produced parental breeding chickens also have the advantages of being good in egg laying performance, free of broodiness, short in production period and high in disease resistance capacity; thus, the breeding cost is saved, economic benefits are improved, and breeding profits are increased.

Description

technical field [0001] The invention relates to the technical field of genetic breeding of poultry, in particular to the technical field of matching of slow-speed super-high-quality parental breeder chickens. Background technique [0002] In the field of broiler breeding in my country, according to the growth rate of broilers, broilers released before 70 days of age are generally called fast large broilers, broilers released at 70-90 days of age are called medium-speed broilers, and broilers released at 90-110 days of age are called medium-speed broilers. Broilers are called slow-type high-quality broilers, and broilers over 110 days of age are called slow-type super-high-quality broilers. Broilers over 110 days of age have better meat quality and flavor due to their sexual maturity and body maturity, which are suitable for Chinese consumers. However, in the breeding process of slow-speed super high-quality broilers, there is no universal grandparent chicken hen like fast la...

Problems solved by technology

However, in the breeding process of slow-speed super-high-quality broilers, there is no common grandparent female parent like fast large-scale broilers and medium-speed broilers. Therefore, in the breeding process of slow-speed high-quality chickens, there are generally several matching lines that need There are several grandparent female parents, resulting in too much occupation of chicken coops, breeding grounds, and breeding facilities. Because of raising a large number of grandparent chicken female parents, feed, veterinary drugs, vaccines, labor, water and electricity fees, and breeding costs are all costs. a huge expense

Due to the high cost of breeding, the price of super high-quality broiler chickens is relatively high, which is difficult for ordinary consumers to accept
