Wild pig, domestic pig and hybrid pig cross breeding and feeding method

Abstract

The invention discloses a crossing breeding and feeding method of wild boars, domestic pigs and hybrid pigs. The wild boars are not fit for feeding and popularization for the reasons that the number of the wild boars is limited, the meat is not fine and the skin is thick, and mouthfeel is worse. The wild boars are oestrous seasonably, produce fewer piglets, and are not easy to feed wild boars. However, the interest of people of pursuing venison and changing taste is increasing. The method for domesticating wild boars is a task that people pay attention to. The method includes: choosing long and white sows or big and white sows, carrying out crossing breeding through crossing generation I, backcrossing generation II, horizontal crossing generation I, and side crossing generation II of the sows and wild boars, total 6 generations. 12-16 months are required for one generation; or choosing duroc sows, carrying out crossing breeding through crossing generation I, backcrossing generation I, horizontal crossing generation II within lines, and horizontal crossing generation III among lines of the duroc sows and wild boars, total 7 generations, 12-14 months are required for each generation. The crossing breeding and feeding method of wild boars is used for crossing breeding and feeding.

Description

Technical field: [0001] The invention relates to a method for improving wild boar hybridization. Background technique: [0002] The number of wild boars is limited, the meat is thick and the skin is thick, and the taste of the meat is poor. It is not suitable for simple domestication and promotion. Moreover, wild boars are in estrus seasonally, with few litters and difficult to raise. And there is a growing interest in seeking game and improving taste. The domestication of wild boars has become a subject of widespread concern. Invention content: [0003] The purpose of the present invention is to establish a hybrid offspring of breeding domestic pig and wild boar, so that the offspring can combine the length of domestic pig and wild boar and show better heterosis. High, adaptable, strong game, and can overcome the seasonal estrus of wild boar, less litter and difficult to raise, so that it can reproduce and raise normally, and then provide green, pollution-free, deliciou...
