Embodiment

[0047] 1. Matrilineal breeding

[0048] Ningxiang pigs, Shaziling pigs, Luchuan pigs or Qianshao Hua pigs are used as the female parent, and Ningxiang pigs are crossed with Berkshire pigs, Shaziling pigs are crossed with Berkshire pigs, and Luchuan pigs are crossed with Berkshire pigs Crossbreed with Qianshao Hua pig and Berkshire pig and divide into four groups, compare the binary hybrid sows obtained from the four groups of crosses, and select the best combination as Qianshao Hua pig through the determination of slaughter rate, reproductive performance and meat quality with Berkshire pigs. Table 1 shows the test results of four groups of hybrid sows, among which the hybrid sows obtained by crossing Qianshao Hua pigs and Berkshire pigs have the best performance and the same body shape and appearance.

Abstract

The invention discloses a method for breeding a matching line of commercial pigs, suckling pigs and roasted suckling pigs. The method for breeding a matching line of commercial pigs comprises the following steps: (1) using Berkshire pigs as the female parent of the matching line, and using Qianshao Hua pig is used as the female parent of the mating line, and the female parent is obtained by crossbreeding; (2) Large White pig is used as the terminal male line, and the female parent is selected for crossbreeding to obtain commercial pigs. Combining the differences of the three populations, the heterosis in a single quantitative trait is greater, and the commercial pigs bred have strong adaptability, excellent meat quality, high slaughter rate, and a fat-to-thin ratio of 1:1, which is suitable for processing baked products.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a breeding method for matching lines of commercial pigs. In addition, the present invention also relates to a suckling pig and a roasted suckling pig obtained by the breeding method of the matching line of commercial pigs. Background technique [0002] Suckling pigs are one of the best-selling livestock products in domestic and foreign markets. Due to the advantages of short production cycle, low cost and high benefits, suckling pig breeding is a good project for the structural adjustment of animal husbandry. [0003] Roast suckling pig has always been a delicacy that people like, and it is consumed in large quantities all over the world, especially in Japan, South Korea and some Southeast Asian countries. Pigs for roasting need to contain an appropriate amount of fat to be roasted with high quality. After roasting, the skin should be smooth and tender, the skin and fat...
