Abstract

The invention provides a cultivation method for multi-rib hybridization boars with high applicability. The cultivation method includes the steps: S10 selecting varieties or strains with more number and high applicability in the local area as female parents; S20 selecting the boars with allelic genes increasing number of ribs as male parents; S30 eliminating the all boars after the female parents and the male parents generate later generations, and reserving sows to obtain first-generation multi-rib hybridization sows. According to the cultivation method, multi-rib major gene cultivation technologies are controlled, and multi-rib hybridization fragrant pigs are selected and cultivated by the aid of a high-level and large-scale system of gene cultivation and conventional cultivation. The new fragrant pigs are more in rib and carcass lean meat, rapid in growth, excellent in meat flavor, good in reproductive performance and high in feed conversion.

Description

technical field

[0001] The invention relates to a method for cultivating a new breed of pig, in particular to a method for cultivating a multi-rib hybrid pig with strong applicability. Background technique

[0002] Pigs belong to vertebrates. The spine of pigs is divided into cervical, thoracic, lumbar, sacral and coccyx. The number of cervical, sacral and coccyx of pigs is relatively fixed, while the number of thoracic and lumbar vertebrae is different. The thoracic vertebra is also commonly known as ribs. The number of pork ribs is an important economic trait, and its heritability is as high as 0.6 or more. The number of ribs is significantly related to the carcass length of pigs. With the increase of the number of ribs, the carcass length of pigs also increases accordingly. Each increase in the number of ribs can increase the body length by about 80mm, and the meat production of pigs has also been improved. corresponding increase.
