A kind of breeding method of special wild boar

Abstract

The invention provides a special wild pig breeding method. The method comprises the following steps: 1, Tibetan wild boar (paternal line) and Northeastern wild boar (maternal line) are hybridized, such that purebred wild boar I is obtained; 2, purebred wild boar I (paternal line) and Tibetan wild boar (maternal line) are hybridized, such that purebred wild boar II is obtained; 3, wild boar II (paternal line) and Duroc (maternal line) are hybridized, such that 50% wild pig is obtained; 4, 50% wild pig (paternal line) and Duroc (maternal line) are hybridized, such that 25% wild pig is obtained; and 5, 25% wild pig (paternal line) and purebred wild boar II (maternal line) are hybridized, such that 62.5% wild pig is obtained. The bred wild pig with 62.5% wild boar bloodline has good physique, hypoxia resistance, low-temperature resistance, and good virus resistance. The average daily weight gain of the wild pig is flat with that of existing domestic pigs.

Description

technical field [0001] The invention relates to the technical field of wild boar breeding methods, in particular to a special wild boar breeding method. Background technique [0002] At present, a large number of wild boars (or wild boars) obtained by crossbreeding wild boars and domestic pigs have been bred. Because of their lean meat, high-quality meat rate, and strong adaptability, they are widely promoted. However, since the daily weight gain decreases with the increase of wild boar blood content, the wild boar blood in the wild boar that is generally promoted at present is not higher than 50%, which leads to the obvious reduction of the ability of wild boar to resist viruses. At the same time, death cannot be avoided, which brings huge economic losses to the farmers. However, when the wild boar bloodline is higher than 50%, although the ability of the wild boar to resist the virus is obviously improved, the weight gain of the wild boar slows down, which is also not con...

However, since the daily weight gain decreases with the increase of wild boar blood content, the wild boar blood in the wild boar that is generally promoted at present is not higher than 50%, which leads to the obvious reduction of the ability of wild boar to resist viruses. At the same time, death cannot be avoided, which brings huge economic losses to the farmers.

However, when the blood of wild boar is higher than 50%, although the ability of wild boar to resist the virus is obviously improved, the weight gain of wild boar slows down, which is not conducive to the improvement of the economic benefits of farmers
