Method for cultivating special wild boars by utilizing hybridization of pigs and wild boars

Abstract

The invention relates to the technical field of herding breeding, in particular to a method for cultivating special wild boars by utilizing hybridization of pigs and wild boars. Pure breed wild boards and duroc sows are hybridized to obtain an F1 generation, so that the excellent characteristics of the duroc sows are absorbed, the shortcoming that the pure breed wild boards is difficult to breed is overcome, the sows of the F1 generation and the pure breed wild boards undergo backcross to obtain an F2 generation, the boars of the F2 generation and Sutai sows undergo hybridization to obtain an F3 generation, the boars and sows of the F3 generation undergo crossing to obtain a basic breeding group, breeding of five generations is performed to obtain a core group, so that the special wild boars contain 37.5% of wild boar blood relationship, 50% of Sutai pig blood relationship and 12.5% of duroc pig blood relationship, the growth speed is quick, and each special wild boar weighs 75 kg when becoming full grown and ready for slaughter at 210 days old. The slaughter rate and the lean meat percentage are high and reach 71.5% and 58.4% respectively. The special wild boars are fresh in meat and rich in wild taste and nutrition and contain 17 amino acids.

Description

technical field [0001] The invention relates to the technical field of animal breeding and breeding, in particular to a method for breeding special wild boars by hybridizing domestic pigs and wild boars. Background technique [0002] Affected by consumer behavior factors, pork consumption accounts for more than 60% of the meat consumption of Chinese residents. With the improvement of living standards, people's demand for pork consumption has gradually changed from ordinary quantitative consumption to high-quality ecological consumption. Pork that is green, healthy, nutritious and unique in flavor has been favored by more and more consumers. And wild boar has aroused people's attention on a large scale due to its own characteristics and quality, so some people do research and exploration on wild boar, and provide a large amount of technical documents and technical means for wild boar domestication. [0003] However, with the continuous improvement of people's living standard...

Problems solved by technology

[0008] But in actual production, adopt the hybridization mode in the prior art to appear monotonous, and then cause the special wild boar character instability, coat color easily occurs separation phenomenon, individual difference is obvious, and its reason is: the heterosis character of the special wild boar cultivated is unstable, Easy to degrade and change, it is difficult to ensure stable production performance in large-scale production

At the same time, only Jiangkou radish pigs are used for hybrid production, which limits the production of special wild boar high-quality pig breeds and hinders the development of wild boar breeding industry
