Research method for hybridization combinations of meat pigeons

Abstract

The invention discloses a research method for hybridization combinations of meat pigeons. According to the method, the egg laying amount and the four-week body weight are main screening traits, a breeding method combining individual breeding with family breeding is applied, Columba W series, White Carneau K series and Ao Feng A series are continuously bred for three generations, and specialized lines with genetic stability and uniform traits are cultivated; on that basis, the combining abilities of the four hybrid combinations are determined, and a two-line hybrid female parent for three-linematching is screened out. The research method has the advantages that three generations of the specialized lines, which take the egg laying amount and the four-week body weight as the main screening traits, are bred according to the respective characteristics of the Columba W series, the White Carneau K series and the Ao Feng A series, and the specialized lines with stable genetic properties and up-to-standard performance are cultivated.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and relates to a method for researching a hybrid matching combination of meat pigeons. Background technique [0002] In the process of poultry breeding, researchers have increased the growth rate of poultry through a large number of experiments, but they often ignore whether the bone strength of the poultry can bear its excessive growth rate, followed by a series of leg 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 maps, accurate positioning of functional genes and QTLs, molecular marker-assisted selection, genetic diversity, and genetic relationship identification guided by DNA fingerprints. The DNA molecular marker technology of pigeons is relatively late in the research of chickens, ducks and geese. How...

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
