Breeding method of penta-breed hybrid pigs

Abstract

The invention discloses a breeding method of penta-breed hybrid pigs, and relates to the technical field of pig breeding and production. The method includes the steps that 1, progenitor Hampshire male pigs and progenitor northern-Guizhou female black pigs are subjected to cross fertilization, and male pigs in generated hybrid pigs are reserved as parental male parents; 2, great-grandparent male landraces and great-grandparent large Yorkshire female pigs are subjected to cross fertilization, and female pigs in generated hybrid pigs are reserved as progenitor female parents; 3, progenitor durocs and the progenitor female parents are subjected to cross fertilization, and female pigs in generated hybrid pigs are reserved as parental female parents; 4, the parental male parents in the step 1 and the parental female parents in the step 3 are subjected to cross fertilization, and the penta-breed hybrid pigs are generated. According to the breeding method of the penta-breed hybrid pigs, through the five-line combination of Hampshire male pigs, northern-Guizhou female black pigs, male landraces, large Yorkshire female pigs and durocs, the milk performance of the female pigs is good, and the farrowing quantity and the survival rate are high; obtained commercial pigs eat little and grow rapidly; the lean-meat rate is high, and the meat is delicate; the immunity and disease resistance property of the obtained commercial pigs are high; the commercial pigs are large in size, the four limbs of each commercial pig are strong, and the number of commercial pigs suffering from the hoof disease is small.

Description

technical field [0001] The invention relates to the technical field of pig breeding and production, in particular to a breeding method for five-element hybrid pigs. Background technique [0002] At present, there are limited resources of excellent pig breeds at home and abroad. At present, rare pig breeds have also inherited "low fecundity of sows, low lactation; poor disease resistance, low survival rate of piglets, and the survival rate is generally below 80%. ; The pigs are small in size, high-quality meat, and low in lean meat. The economic benefit is not good. [0003] Therefore, breeding hybrid pigs with high fecundity, strong pigs, strong disease resistance and high lean meat rate is a subject that pig farmers are eager to research, and it is of great significance to improve pork quality and economic benefits. Contents of the invention [0004] The present invention aims at the above-mentioned existing technical problems, and provides a breeding method for five-el...
