Cultivating method of general-purpose maternal sides of meat and skin dual-purpose rabbits and application of cultivating method

Abstract

The invention provides a cultivating method of general-purpose maternal sides of meat and skin dual-purpose rabbits and an application of the cultivating method. The cultivating method comprises the steps of selecting white male rex rabbits and white female meat rabbits, performing mating to produce F1-generation rabbits, enabling F1-generation female rabbits and the white male meat rabbits to bemated to produce F2-generation rabbits, through test cross with rex rabbits, selecting and remaining Rr heterozygosis type F2-generation female rabbits, performing backcross on the Rr heterozygosis type F2-generation female rabbits and white male meat rabbits to produce F3-generation rabbits, through test cross with the rex rabbits, selecting and remaining Rr heterozygosis type F3-generation maleand female rabbits, enabling the Rr heterozygosis type F3-generation male and female rabbits to be subject to athwart cross to produce F4-generation rabbits, selecting F4 representative types as individuals of rex rabbit hair types, establishing underlying groups, and then performing locking subculture so as to complete cultivating of the general-purpose maternal sides of the meat and skin dual-purpose rabbits. The general-purpose maternal sides of the meat and skin dual-purpose rabbits, obtained through breeding, have great production and application value in breeding or producing of domesticrabbits.

Description

technical field [0001] The invention belongs to the technical field of livestock breeding, and in particular relates to a breeding method for a common female line of a rabbit with both meat and skin and its application in rabbit breeding or rabbit production. Background technique [0002] People raise rabbits mainly for the production of rabbit meat and rabbit skin, and use mutations in coat genes to breed specialized meat rabbits and rex rabbits respectively. In fact, the breeds of meat rabbit and rex rabbit are dual-purpose rabbits with different emphasis on meat and leather production. However, due to the poor quality and low utilization value of the skins of meat rabbits, the slow growth and reproduction of rex rabbits, and the low efficiency of meat use, these two types of specialized species often cannot take care of both meat and skin, and they are completely separated in breeding production. There have been two outstanding problems in the production of domestic rabb...

Problems solved by technology

However, due to the poor quality and low utilization value of meat rabbit skins, slow growth and reproduction of rex rabbits, and low meat efficiency, these two types of specialized species often cannot take care of both meat and skin, and they are completely separated in breeding production.

There have been two outstanding problems in the production of domestic rabbits for a long time: one is the lack of specialized maternal breeds with good reproductive performance in the production of rex rabbits, resulting in low reproductive efficiency and high production costs of rex rabbits; The market price of rabbit meat and skins changes, leading to the frequent switching of breeding rabbits and rex rabbits between rabbit breeding enterprises and farmers, which correspondingly generates high replacement costs of breeding rabbits and causes a large loss of operating time
