Problems solved by technology

But the feather color of the offspring is messy, and the average white feather rate (white feather area above 95%) of the unselected white feather parent offspring is lower than 40%, resulting in a serious reduction in the value of their feathers

Embodiment 1

[0048] Embodiment 1, method for breeding female parent of hybrid duck between white feathers

[0049] 1. Breeding of female parent of white feather intergeneric hybrid duck

[0050] 1. Breeding of the 0th generation Beijing duck crossbreeding female parent

[0051] 1) Generation 0 male and female Beijing duck selection

[0052] In July 2011, 240 Peking duck female ducks (self-breeding on the farm) were selected as the 0-generation basic group, and each Peking duck female duck was raised separately in a numbered egg production test cage, and the method of artificial insemination was used to make the 0-generation Follicular fertilization of Beijing duck female ducks: twice a week, collect the semen of 20 Cremo white-feathered male Muscovy ducks (provided by Jilin Zhengfang Company) each time, and an average of about 2ml of semen can be collected from each male Muscovy duck. Normal saline 1 : 1 dilution, randomly mixed in four 10ml centrifuge tubes to make mixed semen. Collect...

Abstract

The present invention discloses a breeding method for a white-feather intergenerically hybridized duck female parent. As an intergenerically hybridized feather color genetic mechanism is relatively complex, and selective advance by using a simple offspring phenotype is extremely slow, the invention creates a selecting method. By adopting a female parent offspring measuring method, by virtue of an artificial insemination technology and integrating an individual selection method and a family selection method, enclosed breeding and offspring production are performed for seed selection of about 5 generations, so that the white feather rate (the white feather area reaches over 95%) of intergenerically hybridized offsprings is significantly improved, and the genetic stability is good.

Description

technical field [0001] The invention relates to the field of biological technology, in particular to a method for breeding female parents of hybrid ducks between the genus White Feather. Background technique [0002] The offspring of duck intergenus hybrids have obvious heterosis without losing the advantages of their parents, and their meat is tender and lean, which is suitable for production and processing. But the feather color of the offspring is messy, and the average white feather rate (white feather area is more than 95%) is lower than 40% in the offspring of the white feather parents that have not been selected, resulting in a serious reduction in the value of their feathers. During the production, it was found that the feather color of the half-sibling offspring of the same white-feathered male duck crossed between duck genera was extremely variable, while the feather color inheritance of the offspring of full-sib or half-sibling white-feathered female ducks was rel...
