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 them 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 multiplication-strain breeding method for commercial pigs, and a suckling pig and roast suckling pig. The multiplication-strain breeding method of the commercial pig comprises the following steps: (1) taking Berkshire pigs as a female-parent male line of a multiplication strain, taking Qianshao spotted pigs as a female-parent female line of the multiplication strain, andcarrying out hybridizing to obtain female parents; and (2) taking big white pigs as a terminal male line, and selecting the female parents for hybridization, so as to obtain the commercial pigs. Differences of three populations are gathered, so that the heterosis on a single quantity trait is larger, the bred commercial pigs have high adaptability, the meat quality is good, the slaughter rate is high, the ratio of lean to fat is 1:1, and the bred commercial pigs are suitable for processing roast 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.
