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.
