Breeding method for reducing wild nature of cage culture local chickens for breeding

A wild and native chicken technology, applied in the field of breeding native chicken genetics and poultry genetics, can solve the problems of difficulty in effectively reducing native chicken wildness, reducing the egg-laying performance and reproductive performance, and low heritability of breeding native chickens. Defects of wild hard breeding, improvement of egg-laying performance and reproductive performance, and effect of improving breeding efficiency

Problems solved by technology

Due to these wild natures of breeding native chickens, it leads to poor uniformity of chicken flocks in the cage stage, which reduces the egg production performance and reproductive performance of breeding native chickens, so the breeding value is low
The wildness of native chickens is controlled by multiple micro-effect genes, which belong to low heritability traits, and it is difficult to effectively reduce the wildness of native chickens through traditional phenotypic breeding methods

Embodiment 1

[0008] A breeding method to reduce the wildness of native chickens for cage breeding. On March 13, 2012, 500 100-day-old Lingshan native roosters and 6000 100-day-old Lingshan native hens were selected as breeding materials for reducing wildness. , Through 60 days of observation, select 60 roosters and 1,200 Lingshan native hens with the least wild performance type and number of wild performances to form 60 generation 0 families according to the male-to-female ratio of 1:20, and collect eggs and hatch according to the family. Family hen numbers pack the eggs of the same hen number in the same net bag when the eggs are placed on the plate, and follow the family seedling emergence process at the time of emergence, register the rooster number, hen number, and chicken wing number to form generation 0 System data of the 1st generation. Generation 1 chicks were raised in the same house during the brooding period, rearing period and laying period, and were raised by the same breeder a...

Abstract

The invention discloses a breeding method for reducing the wild nature of cage culture local chickens for breeding. Aiming at the current situation that due to the wild nature of local chickens, the local chickens are aggressive, fight for food and peck features, cage culture dullness and cage culture stress disorder are generated, and the breeding value of the local chickens is not high, local chickens with the strong wild nature are removed through a family breeding method. According to the local chickens for breeding bred after reduction of the wild nature, the defect that local chickens for breeding are difficult to breed due to the strong wild nature is overcome, the egg laying performance and reproductive performance of the local chickens for breeding are obviously improved, and then breeding benefits of the local chickens for breeding are increased.

Description

Technical field [0001] The present invention relates to the technical field of poultry genetics, in particular to the technical field of breeding native chicken genetics. Background technique [0002] The chickens currently raised in my country are mainly fast and large broilers imported from abroad, but the taste and flavor of such fast broilers cannot cater to the preferences of Chinese consumers. Due to their special flavor and taste, local chickens in China are increasingly being consumed. People accept it, so more and more broiler breeding companies are engaged in the production and management of native chickens. However, due to long-term breeding in natural environment, native chickens have been domesticated into a strong wild nature. The specific manifestations are combative, competitive, pecking addiction, cage rigidity and cage stress disorder in the chicken cage. Due to the wild nature of the breeding native chickens, the chicken flock uniformity is poor in the cage sta...
