Embodiment 1

[0013] Two-line mating hybridization is adopted, that is, the hybrid pig of Changbai Mountain wild boar and Songliao black pig is set as the male parent (A), and the Songliao black pig is the female parent (B), that is, A×B two-line mating cross.

[0014] According to the general principle of specialized male-matrilineal division of labor, combined with comprehensive consideration of factors such as trait heritability, genetic correlation, heterosis and selection intensity, the main selection traits of the matching line are determined to be two growth and fattening traits: growth speed, meat flavor and reproductive traits 1: litter size; meat quality traits: the specific division of labor is as follows, the father (A) line is mainly selected for thick backfat, taking into account the growth rate and the test results of combining ability, and is bred into a line with lean meat and good meat quality and flavor; the female (B) line Because of the large amount of seeds required, li...

Embodiment 2

[0019] Build a population:

[0020] According to the performance division of each line and the status in the supporting breeding system, the selected breeding pigs are strictly identified and selectively bred. The paternal line (A) of Changbaishan black pigs has a scale of 20 males and 100 females, 10 bloodlines of male pigs, and 40 bloodlines of sows, with the same body shape and appearance; the female parental line (B) is Songliao black pig, a local pig breed breeding strain, and the core The group size reaches 30 males and 300 females.

[0021] Breeding measures:

[0022] ①Technical route: Guided by the theory of modern genetics and breeding, guided by the latest theory of the supporting system, adopting the technical route of combination of closed and incomplete closed-generation selection, with a generation interval of 1.5 years and one generation, the reserve breeding pigs are selected and retained The ratio is: boar A line 10:1, B line 5:1; sow A line 2:1, B line 3:1....

Abstract

A method for culturing the hybrid meat pig includes such steps as hybridizing between the Changbai mountain wild boar as male parent and Songliao black pig as female pig, selectively culturing the hybrid descendant to obtain Changbai mountain black pig, and transverse hybridizing between said Changbai mountain black pig as male parent and Songliao black pig as female parent. The resultant descendant features its excellent pork.

Description

technical field [0001] The invention relates to a method for cultivating meat-eating pigs, in particular discloses a method for cultivating meat-eating pigs with Changbai Mountain wild boar as the male parent and Songliao black pig as the female parent, and belongs to the technical field of animal breeding. Background technique [0002] Changbai Mountain wild boar has a high reproductive rate and cub survival rate, and has the characteristics of strong stress resistance, strong disease resistance, tolerance to rough feeding, and unique meat flavor. However, this breed is also unfavorable for breeding and slow growth and development Defects such as poor palatability of meat and meat. Therefore, through hybridization with Changbai Mountain wild boar as the male parent, a new breed of hybrid matching line with good meat quality and unique flavor can be bred to produce high-quality and high-grade pork. After retrieving the relevant literature, there is no literature report on t...
