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.

African swine fever virus (ASFV) is the etiological agent of a contagious and often lethal viral disease of domestic pigs. Control of ASF has been hampered by the unavailability of vaccines. Experimental vaccines have been derived from naturally occurring, cell culture-adapted, or genetically modified live attenuated ASFVs; however, these vaccines are only successful when protecting against homologous viruses. Among viral genes reported to be involved in virulence are components of the multi gene family (MGF). Here we report the construction of a recombinant ΔMGF virus derived from the highly virulent ASFV Georgia 2007 (ASFV-G) isolate. In vivo, ASFV-G ΔMGF administered intramuscularly (IM) to swine at either 10² or 10⁴ HAD₅₀ are completely attenuated; the inoculated animals are completely asymptomatic. Animals infected with 10² or 10⁴ HAD50 of ASFV-G ΔMGF are protected against the presentation of clinical disease when challenged at 28 days post infection with the virulent parental strain Georgia 2007.
