Problems solved by technology

In 2000, my country's import volume exceeded 5 million tons for the first time, and reached 1,300 tons in 2007, and more than 80% of them were feed fast-fed pork imported from Brazil and Argentina. Although the impact of fast-feeding pork on human health is still inconclusive, but there are many controversies

Embodiment 1

[0030] The invention provides a method for cultivating multi-rib hybrid pigs with strong applicability, the specific process is as follows:

[0031] S10: Select a variety or line with a large number and strong adaptability in this area as the female parent;

[0032] S20: Males select boars carrying favorable alleles for increasing the number of ribs;

[0033] S30: Eliminate all boars from the offspring of the female parent and the male parent, retain the sows, and obtain a first-generation multi-rib hybrid sow.

[0034] As mentioned above, it needs to be understood that the pig's spine is composed of five parts: cervical vertebra, thoracic vertebra, lumbar vertebra, sacral vertebra and tail vertebra. The number of cervical and sacral vertebrae is basically fixed, 7 and 4, respectively. The number of thoracic and lumbar vertebrae is different. The number of thoracic vertebrae in modern Western commercial pigs ranges from 14 to 16, and the number of lumbar vertebrae is 5 to 7....

Embodiment 2

[0054] The invention provides a method for cultivating multi-rib hybrid pigs with strong applicability, which uses a three-way hybrid method to select and breed multi-rib hybrid pigs; the specific process is as follows:

[0055] S10: Select a variety or line with a large number and strong adaptability in this area as the maternal parent;

[0056] S20: The male parent is a boar selected to carry an allele favorable for increasing the number of ribs;

[0057] S30: Eliminate all boars from the offspring of the female parent and the male parent, and keep the sows, which is the first generation of hybrid multi-rib hybrid sows;

[0058] S40: Using the first-generation multi-rib hybrid pig as the female parent, the male parent is a boar carrying a favorable allele for increasing the number of ribs to obtain a triple-cross multi-rib hybrid pig.

[0059] As mentioned above, it needs to be understood that the pig's spine is composed of five parts: cervical vertebra, thoracic vertebra, ...

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. [0003] my country is a big consumer o...
