Breeding and Breeding Methods of Hybrid Breeds between Dashi Mountain Wild Boar and Guangxi Luchuan Pig

Abstract

The invention discloses a breeding and a culture method of hybridization pig of Dashishan area wild boar and Guangxi Luchuan pig, and a wild boar from southern Dashishan area is selected as the father and a Guangxi Luchuan pig is selected as the mother for hybridization, obtaining male pigs of a first generation; and the male pigs of the first generation are selected for hybridization with Guangxi Luchuan female pigs to obtain a hybridized pig. The culture method is characterized in that steps like hybridization, domestication, culture environment management, female pigs and piggy breeding management and hog breeding management are included; the wild boar bred in this way has the advantages of strong field survival adaptability, mild temper, strong disease resistance, fast growth speed, good meat quality, crisp leather, little fat meat, 2.3 times of giving birth a year and 10-12 pigs every time, and the forage consumption is 50% less than that by domestic breeding.

Description

technical field [0001] The invention relates to a method for breeding and cultivating hybrids of domestic pigs and wild boars, in particular to a method for breeding and cultivating hybrids of Luchuan pigs and wild boars in Guangxi. Background technique [0002] Wild boar, Latin scientific name Sus scrofa, another name: wild boar, pig is an animal. Divided into European wild boar and Asian wild boar, the number of chromosomes 2n between 36 and 38 has no reproductive barriers between each other. There are 27 subspecies of wild boar in the world, and there are some differences between subspecies and subspecies of karyotype. The number of chromosomes (2n) is between 36-38, such as Western European wild boar 2n=36 or 37, Japanese wild boar 2n=38, But there is no reproductive barrier between each other. They are widely distributed in the world, but due to factors such as human hunting and the sharp reduction of living environment space, the number has decreased sharply, and the...

Problems solved by technology

[0012] The above-mentioned documents have provided wild boars with local pig breeds or foreign pig breeds to obtain new varieties and methods for raising new breeds of hybrid pigs. The wild boars obtained have the advantages of rough feeding resistance, strong disease resistance, and good meat quality. However, as everyone knows, due to Wild boars have been living in the wild where food is scarce for a long time, and their reproductive rate is very low. Generally, they can only produce one litter per year, with 4-8 heads per litter. However, the reproductive rate of new varieties obtained by crossing wild boars with local or foreign pigs has increased. But generally there are only two litters, with 6-10 heads per litter. Even if the birth rate is increased, the survival rate is low due to poor care of the sow wild boars herding sheep. Some eat more picky feed
