Embodiment 1

[0018] Embodiment 1 hybrid combination test and combining ability determination

[0019] A crossbreeding experiment was conducted on three breeds of halothane-free recessive gene Berkshire pigs, Duroc pigs, and long-term binary pigs, and fattening experiments and slaughter tests were carried out on the crossbred commercial pigs to determine the relationship between each crossbreeding combination. The combining power of the combination is shown in Table 1.

[0020] Table 1 hybrid combination

[0021]

[0022] The experimental results show that A and B have similar crossing patterns, and the terminal female parents are the same; C and D have similar crossing patterns, the first female parents are the same, but the terminal male parents are different. From the point of view of the purpose of mating line breeding, it is mainly to improve the production efficiency of commercial pigs. Because the terminal female parent of A and B is a local pig breed, the lean meat rate of comme...

Embodiment 2

[0026] Example 2 Breeding of Berkshire pigs without halothane recessive gene

[0027] The breeding group of Berkshire pigs with no halothane recessive gene is used as a matching line. The breeding group has 5 pedigrees, the number is 150, and the ratio of male to female is 1:5. Conventional breeding methods are used to breed high lean meat rate and meat quality. The halothane-free recessive gene Berkshire pig population with good traits, consistent body shape and appearance, and stress resistance improves the overall performance of the population.

[0028] The Berkshire pigs bred by the method have high lean meat percentage, good meat quality traits, consistent body shape and appearance, and strong stress resistance ability.

Embodiment 3

[0029] The breeding of embodiment 3 Duroc pigs

[0030] Taking Duroc pigs as the breeding group, the breeding group has 5 pedigrees, the number is 150, and the male-to-female ratio is 1:5. Conventional breeding methods are adopted to breed robust physique, strong stress resistance, fast growth speed and high feed utilization efficiency. High, high carcass lean meat percentage, good meat quality Duroc pig population. The growth rate is above 650g / d, and the lean meat rate is above 60%.

Abstract

The present invention relates to the husbandry technology field, and especially relates to a method for hybridizing a high-quality boar commercial strain with a commercial pig. The method comprises the steps of (A) using a fluothane-free recessive gene berkshire as a first male parent of the commercial strain, using a duroc as a first female parent of the commercial strain, and hybridizing and obtaining a badu hybrid pig; (B) using a landrace as a second male parent of the commercial strain, using a large white pig as a second female parent of the commercial strain, and hybridizing and obtaining a grown binary pig; and (C) selecting the badu hybrid pig obtained by hybridizing in the step (A) as a terminal male parent of the commercial strain, using the grown binary pig obtained by hybridizing in the step (B) as a terminal female parent of the commercial strain, and hybridizing and obtaining a high-quality commercial pig. The high-quality commercial pig grows fast with a speed of 726g/d, has uniform fat and lean meat without PSE meat, and can mature in advance for about 10-15 days, meat quality trait is good, product quality is reliable, market prospect is good, and production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a method for hybridizing commercial pigs with matching lines of high-quality breeding pigs. Background technique [0002] From the 1980s to the early 1990s, the pig industry in Western countries such as the United States and the United Kingdom mainly used Large White pigs, Landrace pigs, and Duroc pigs as breeding pigs for the production of "foreign three-yuan" meat pigs. After the emergence of self-matching lines, short In a few years, 80% of the market share of pig production has been occupied by this new production model. Compared with existing pig breeds, matching pigs have greater variety advantages. Traditional high-quality pig breeds often only show one or two advantages such as high lean meat percentage and fast growth, while matching pigs can embody them in a concentrated manner. Multiple advantages. JeanNAVEAV of the French Academy of Sciences used Chinese Ta...
