A kind of cultivation method of Sumei black pig

Abstract

The invention discloses a breeding method for Sumei black pigs. The method comprises the following steps that firstly, parents are selected, wherein Meishan pigs and Berkshire pigs are selected to serve as the parents for hybridization, and a first Sumei generation is obtained; secondly, a first generation candidate pig group is obtained, wherein a certain scale of the first Sumei generation pigs are selected, a foundational group is built, and the first generation candidate pig group is obtained; thirdly, the Sumei black pigs are obtained, wherein boars and sows in the first generation candidate pig group randomly mate, and breeding pigs are reserved from the obtained first farrow, and the second generation is built by the boars and sows in the breeding pigs; the following generations can be done in the same manner, continuous progeny breeding can be conducted in a closed small group, after selection and breeding of 3-5 generations, then group expanding and popularization are conducted, and the Sumei black pigs with stable inheritable characters are obtained. On the basis that closed continuous progeny breeding is conducted on a traditional building group, combined with the molecular marker technology and the BLUP estimated breeding value method, individual stallion and progeny selection can be effectively carried out, a scientific basis is provided for variety breeding, and the pertinence and accuracy of progeny selection and reserving are improved.

Description

technical field [0001] The invention belongs to the field of animal husbandry industrialized production, and in particular relates to a method for cultivating Samui black pigs. Background technique [0002] At present, domestic local pig breeds or bred pig breeds focus on improving lean meat percentage and meat quality, while foreign pig breeds focus on lean meat breeds and matching lines with high litter performance. [0003] The existing local pig breeds have significant advantages in terms of litter size and adaptability, but have defects in growth speed, lean meat percentage and meat quality; while foreign imported breeds have significant advantages in growth speed and lean meat percentage, However, there are defects in fecundity and adaptability. [0004] In addition, in the breeding process of pig breeds, the traditional method of establishing a basic group for closed breeding is often used, while the breeding of Sumei black pigs carried out by us adopts the combinati...

Problems solved by technology

[0003] The existing local pig breeds have significant advantages in terms of litter size and adaptability, but have defects in growth speed, lean meat percentage and meat quality; while foreign imported breeds have significant advantages in growth speed and lean meat percentage, But there are deficiencies in fecundity and adaptability

[0004] In addition, in the breeding process of pig breeds, the traditional method of establishing a basic group for closed breeding is often used, while the breeding of Sumei black pigs carried out by us adopts the combination of traditional breeding and molecular breeding, which speeds up the breeding process

[0005] Although it has been reported that Meishan pigs and Berkshire pigs have been crossed to produce commercial pigs, in fact, the first generation of Meishan pigs and Berkshire pigs can only be used as hybrid parents to produce commercial pigs, and purebred breeding of hybrid pigs cannot be carried out Otherwise, the offspring's hair color will change from black to flower color is very serious, and only after 3-5 generations of in-group selection on the established basic group can the genetically stable offspring of black pigs be formed
