A kind of method for the research on the hybrid combination of meat pigeon

Abstract

The invention discloses a method for researching a crossbreeding matching combination of meat pigeons. The egg production and four-week-old body weight are used as the main screening traits, and the breeding method of individual breeding and family breeding is carried out at the same time. The white Kanu pigeon K line and the Aofeng pigeon A line were continuously selected for three generations to breed specialized strains with stable genetics and neat traits, and based on this, the combining ability of four cross combinations was determined to screen out possible It is used as the female parent of the two-line hybrid for three-line matching. According to the traits and characteristics of the white-feathered king pigeon W line, the white Kanu pigeon K line and the Aofeng pigeon A line, through the selection of three generations of specialized strains with egg production and four-week-old body weight as the main selection characteristics, bred into Specialized strains with stable genetic traits and performance standards have been established.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and relates to a research method for cross-matching combination of meat pigeons. Background technique [0002] In the poultry breeding process, researchers have improved the growth rate of poultry through a large number of experiments, but in the process, they often ignore whether the strength of the poultry bones can support its excessive growth rate, followed by a series of legs. disease, therefore, improving bone strength to address poultry leg disease has become an important goal in broiler production. DNA molecular marker technology has been widely used in poultry, including the construction of genetic map, accurate mapping of functional genes and QTL, molecular marker-assisted selection, genetic diversity, and identification of kinship guided by DNA fingerprints. The DNA molecular marker technology of pigeons is relatively late compared to chickens, ducks and geese, but with the e...

Problems solved by technology

In the early stage of meat pigeon breeding, farmers will introduce a large number of foreign high-quality meat pigeon breeds for breeding, but due to the lack of systematic breeding knowledge, effective breeding has not been carried out. If things go on like this, it will be found that most pigeon farms will have inbreeding pigeons The resulting decline in the reproductive ability of offspring or the occurrence of trait separation and performance degradation
