Low-cost matched breeding method for white feather broilers

Abstract

The invention relates to a low-cost matched breeding method for white feather broilers. According to the method, recessive white Plymouth rocks serve as a specialized strain female parent paternal line, high-yield laying hens serve as a specialized strain female parent maternal line, the recessive white Plymouth rocks and the high-yield laying hens are hybridized to generate female parents, and aCornish variety serves as a male parent to be hybridized with the female parents to generate a commercial generation of a specialized strain. Leukemia and pullorum disease full-group general test is preferably carried out on specialized strain progenitor chicken flocks, regular spot test is carried out on the parents, and leukemia individuals and pullorum disease positive individuals are eliminated. Pure line breeding is preferably carried out on the specialized strain paternal line, the female parent paternal line and the female parent maternal line. The breeding cost of the commercial generation is reduced, the growth speed of the commercial generation can be ensured, and the production cost is reduced.

Description

technical field [0001] The invention relates to a low-cost matching seed production method for white-feathered broilers, which belongs to the field of biological seed industry. Background technique [0002] At present, my country's white-feather broiler market is dominated by imported varieties such as Ross 308, AA+, and Hubbard, which have the characteristics of rapid weight gain in the early stage, high proportion of breast meat, and large meat production. Cultivated by consumer demand, mainly used for fast food. However, Chinese consumers prefer chicken wings and drumsticks, and less consumption of chicken breast meat. Therefore, chickens used for fast food only need to have a higher ratio of wings and legs, and a relatively lower percentage of breast muscle. In actual production, most of the white-feathered broilers are released in advance at the age of 37-38 days. This can ensure the requirements of chickens for fast food and reduce the risk of death. The fastest-growin...

Problems solved by technology

In actual production, most of the white-feathered broilers are released in advance at the age of 37-38 days. This can ensure the requirements of chickens for fast food and reduce the risk of death. The fastest-growing day-old for white-feathered broilers is 35- At the age of 42 days, early slaughter will cause the growth potential of white feather broiler chickens to not be fully developed

In addition, it is difficult to raise breeders of this type of white-feathered broiler chickens, and the utilization efficiency of breeders is low. The average egg production in the whole process is about 180, and the average fertilization rate and hatching rate do not exceed 85%. high

In addition, the provenance of such varieties in China is completely dependent on foreign countries, and the continuous occurrence of epidemics poses a threat to the safety of provenance
