Problems solved by technology

However, the "inner binary" and "inner ternary" commercial pigs are mixed in coat color, which brings a lot of troubles to the purchase, classification, grading and pricing of commercial pigs; The uniformity of the generation is poor, and it is an economic hybrid suitable for the model of small farmers in China, but it cannot meet the requirements of factory farming for product standardization, and it is difficult to form scale, standardization and industrialization

Embodiment

[0051] A breeding method for a high-quality white pig matching line, comprising the following steps and technical points:

[0052] 1 Breeding objectives of matching lines

[0053] Overall idea design: Cultivate 3 specialized strains with their own characteristics, and produce high-quality lean-meat commercial pigs through cross-breeding of 3 strains. The entire breeding system is required to have high production efficiency, the female line has high fecundity, good motherhood, and excellent meat quality; the male line grows fast and has a high lean meat rate; the commercial generation has a uniform appearance, white coat, fast growth and high uniformity, and thin The meat rate is moderate, the disease resistance is strong, the adaptability is wide, and the meat quality is excellent.

[0054] Breeding goals of the sire line (JW1 line):

[0055] (1) The body shape is similar to the original Duroc, but the coat is homozygous for the dominant white gene; (2) The fattening reaches...

Abstract

The invention relates to the technical field of animal breeding and particularly provides a breeding method of a high-quality synthetic white pig line. The method utilizes existing domestic and overseas pig breed resources, a specialized line is bred according to a trait differentiation and selection principle, thus commercial pigs quicker to grow, higher in lean meat percentage, good in meat quality, strong in resistance and high in slaughtering weight uniformity are obtained through hybrid breeding of the specialized line, the problem existing in 'inner binary' and 'inner ternary' breeding systems can be solved, meanwhile local pig breed resources can be also effectively protected and utilized, high-quality pig breeds are provided for industrial large-scale breeding, and the heavy demands for high-quality pork of masses of consumers are met.

Description

technical field [0001] The invention relates to the technical field of animal breeding, and specifically provides a breeding method for a matching line of high-quality white pigs. Background technique [0002] In recent years, with the continuous improvement of residents' living standards and the transformation of consumption concepts, pork with safety, nutrition, and good meat flavor has become more and more popular among consumers. There are mainly two modes of high-quality pig production in my country: one is the purebred production mode of local breed pigs, and the other is the hybrid production mode that uses binary hybridization (inner binary) of local pigs and foreign breeds or uses "Du Changben" Or the so-called "inner triple" hybrid in the form of "Du Daben". The pork produced by the first production mode is of good quality, but due to the long feeding period, high cost, less meat and more fat, and the extremely high price, it cannot meet the market’s large demand f...
