Embodiment 1

[0020] S1). The sow of Jinghong small-eared pig was used as the female parent, and the Bamaxiang pig was used as the male parent to carry out crossbreeding, and a generation of hybrid wild boar was selected; Ear sows are 2-6 years old Bamaxiang pig boars with a weight of 80-150 kg. They are bred by natural hybridization or artificial insemination. The selection criteria for the first generation of hybrid sows are: at birth, select individuals with black coat, healthy and no genetic defects, birth weight greater than 1kg, and 6 or more pairs of effective teats; at the age of four months, select individuals with coat color Sows with black, well-proportioned body shape and good physique were eliminated; at the age of eight months, individuals with thin backfat and fast growth were selected for breeding for the second crossbreeding.

[0021] S2), using the sow of the first-generation wild boar as the female parent, and the second-generation wild boar of Gaoligong Mountain as the m...

Abstract

The invention relates to the technical field of variety pig hybridization, in particular to a cross breeding method of Caoguo pigs. The cross breeding method of the Caoguo pigs comprises the following steps: S1, taking a sow of a Jinghong small-ear pig as a female parent and a Bama minipig as a male parent for hybridization to breed a first-filial generation wild pig; S2, taking a sow in the first-filial generation wild pig as a female parent and taking a second-generation Gaoligong mountain wild boar as a male parent for hybridization to obtain a second-filial generation wild pig; S3, taking a boar in the hybridized second-generation wild pig as a male parent and a sow in the hybridized second-generation wild boar as a female parents for cross-breeding to obtain a cross-bred progeny wild pig; and S4, carrying out 4-6 generations of breeding on the cross-bred progeny wild pig to finally obtain the Caoguo pig variety. Aiming at the defects in the prior art, the invention provides the cross breeding method for the Caoguo pigs, and provides a method for breeding new-variety pigs by hybridizing wild pigs and domestic pigs, so that the bred new-variety pigs integrate the advantages of purebred wild pigs and domestic pigs, and are high in disease resistance, high in farrowing rate and good in meat quality.

Description

technical field [0001] The invention relates to the technical field of breed pig hybridization, in particular to a method for cross breeding of grass-fruit pigs. Background technique [0002] Wild boar is also called wild boar, and there are different varieties of wild boar in different countries and regions. Purebred wild boars generally have thick skin, heavy fishy smell, thick meat, less meat, and low litter rate, so they have a bad taste and are not suitable for raising as commercial pigs. However, purebred wild boars have strong environmental adaptability and disease resistance. The disease resistance is obviously better than that of the raised commercial pigs. In addition, its nutritional value is high, its fat content is low, its fragrance is strong, and it has certain medicinal value, so its market value is relatively high. However, the limited number of purebred wild boars, coupled with the increasing protection of wild animals, leads to the fact that the number of...
