Deka composite line pig breeding pig
NY625—2002
This standard is finalized! ! The breeding system of the Dika system of pigs introduced from Guanjiang Card Manufacturing Company in 2000 and produced by this company is wide-patterned and has the characteristics of the appearance, production and use of the original pigs, the second generation pigs and the cross-ear second generation pigs. The standard is applicable to the evaluation and certification of the matching pigs of the card system. 2 Normative reference documents

3 Understanding and Definitions
The following terms and definitions are used in this standard: 3.1
The original breeding pigs that form the commercial generation of fattening pigs [specialized breeds, the original new pigs can be used to breed the original generation, and are also used to produce the original generation of breeds,
The next generation of breeding pigs
comes from the supplementary pigs! The breeding pigs of the parents of the breeding pigs cannot reproduce by themselves, and can only be used to produce the original breeding pigs. The mother generation
comes from the station generation of breeding pigs, and cannot produce the commercial generation of the unique pigs, the mother generation of breeding pigs does not carry out self-promotion, etc., and the source of the generation of the pigs 3. 4
Estimated breeding value estimatedhreedingvnlue (commercially written as Klt) is the estimated breeding value of an individual, which is also the part of the phenotypic value that can be truly passed on to future generations.
4 Composition, matching method and system of Dika matching pigs and the number of breeding 4.1 Composition of Dika matching spermWww.bzxZ.net
Dika matching pigs include the breeding potential of the next generation and the breeding potential of the next generation. The matching system includes 3 specialized strains, including A, F, and F Representative. The matching system includes three specialized lines, including three pure lines, A line boars, B line sows, A line boars and old quality breeds, and another combination of A and B line sows. The English letters represent: A represents the combination of two parents, A represents the combination of A and B lines, and A represents the combination of A and B lines. 1
