Embodiment 1

[0050] Example 1: The breeding method of southern Anhui wild boar comprises the following steps:

[0051] (1) Breeding Du-Wan sows: Du-Wan hybrid dual sows were obtained by crossing male-line Duroc and female-line Wannan Hua pigs;

[0052](2) Using the purebred wild boar in southern Anhui as the male line, and the duo-anhui hybrid sow as the female line, cross-breed to obtain 50% of the pedigree Anhui wild boar;

[0053] (3) Using purebred wild boars in southern Anhui as the paternal line, and wild boar sows with 50% pedigree in southern Anhui as the female line, crossbreed to obtain wild boars with 12.5% ​​of Du and Anhui bloodlines and 75% of Wannan wild boar ancestry;

[0054] (4) Using 12.5% ​​of Du and Anhui bloodlines, 75% of Wannan wild boar bloodlines as male lines, and 50% of Wannan wild boars as female lines, crossed to obtain 25% of Duan and Anhui wild boar bloodlines.

Abstract

The invention discloses a method for breeding Wannan boars, which includes: subjecting paternal Duroc pigs and maternal Wannan spotted pigs to hybridization to obtain Du-Wan two-way hybrid sows; subjecting pure Wannan wide boars as male parents and the Du-Wan two-way hybrid sows as female parents to hybridization to obtain wild boars 50% of Wannan wild boars; subjecting the pure Wannan male wild boars as male parents and the boars 50% of the Wannan wild sows as female parents to hybridization to obtain wild boars 12.5% of Du-Wan blood and 75% of Wannan wild boars; and finally subjecting the wild boars which are 12.5% of Du-Wan blood and 75% of the Wannan wild boars as male parents and the wild boars 50% of the Wannnan wild boars as female parents to hybridization so as to obtain wild boars 12.5% of Du-Wan blood. By hybridizing the Wannan wild boars, the Wannan spotted pigs and Duroc pigs, the obtained wild boars are stable in hereditary character, high in adaptability, resistant to coarse feed, low in feeding quantity, low in rearing cost, fine in reproductive performance, high in disease resistance, high in meat nutrition value, full of wild taste, high in slaughter rate and good in economic benefit.

Description

technical field [0001] The invention relates to a method for breeding wild boars in southern Anhui, belonging to the field of biological breeding. Background technique [0002] 1. Wannan Huazhu (WNH100) [0003] 1. Southern Wanhua pigs have low requirements on feeding and management conditions, and have a strong ability to resist animal diseases, so they are suitable for free-range breeding by local farmers. This variety has six major characteristics: 1. Early maturity and high reproductive rate. The sows are generally 3-4 months old at maturity and 5-6 months old at mating age; the average estrus cycle is 22-23 days; the gestation cycle is 112 months. ~116 days; multiparous sows per litter 10-14, high-yielding period 7-12 litters; weaning age 28-32 days; 2. Many teats, generally 7-8 pairs, good maternal nature, lactation rate as high as 96% ; The average birth weight of piglets is 0.8kg; the survival rate of piglets is 92.3%. 4. Strong stress resistance and disease resi...
