Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with accompanying drawing, but not as any restriction to the present invention

[0014] Embodiment of the present invention: a breeding method for a new hybrid strain of white-washed pigs and Duroc. In a farm in Shibing County, Guizhou Province, the time is March 2014. Genetic testing, and the white-washed pig used as the male parent in step 2) and the white-washed pig used as the female parent in step 1) cannot be related within six generations.

[0015] 1) The white-washed pigs are used as the female parent and the Duroc as the female parent to carry out crossbreeding, and the hybrid F1 generation is the White-Duroc binary pig;

[0016] 2) The White-Dured hybrid pig is used as the female parent, and the White-washed pig of a different strain from the White-washed pig in 1) is used as the male parent to obtain the White-Dured hybrid pig breed;

[0017] 3) The Baidu hybrid pig breed was fixe...

Abstract

The invention discloses a breeding method for a new Baixi-pig and Duroc hybridization strain. According to the breeding method, Baixi pigs and Duroc are hybridized to introduce the characteristics of the high lean meat percentage and rapid growth of the Duroc; meanwhile, the Baixi pigs and the Duroc are hybridized to obtain Bai-Duroc hybrid pigs to increase the growth speed and the lean meat percentage. But as the meat quality of the Duroc is poorer than that of the Baixi pigs, on the basis of obtaining the Bai-Duroc hybrid pigs, the meat quality is improved by introducing Baixi pigs different from the hybrid female parent, and finally the Bai-Duroc pigs in the target strain are obtained through transversely-fixed copulating of the Bai-Duroc hybrid pigs. The finally-obtained Bai-Duroc strain has high lean meat percentage genes and rapid growth genes of the Duroc and local feature genes of the Baixi pigs; by means of the pigs in the strain, the slow growth characteristic of the Baixi pigs is improved, meat is fresh, fine, smooth and mellow while the high growth speed and the high lean meat percentage are achieved, and economic value and feeding value are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a method for cultivating a new hybrid strain of whitewashed pigs and Duroc. Background technique [0002] As a fine local variety, whitewashed pigs have the characteristics of pure genes, early maturation, resistance to rough feeding, obvious estrus, delicious meat, low cholesterol, and fine meat quality. Slow, small litter size, low economic benefits and other shortcomings, thus affecting its further promotion and breeding. Contents of the invention [0003] The object of the present invention is to provide a method for cultivating a new hybrid strain of whitewashed pigs and Duroc, the pigs bred by the method have the characteristics of fast growth and high lean meat percentage. [0004] The present invention is achieved like this: the breeding method of white-washed pig and Duroc hybridization new line, comprises the steps: [0005] 1) The white-washed ...
