Other breeds you may consider using : the Belgian double muscled pig or hog for extra meat and muscle , the spotted Poland China which can weigh over a ton for size, These 2 are domestic breeds . It looks like you're new here. The head and front quarters are of the black Berkshire breed, while the remainder of the porker is that of a Poland China. In-breeding humans create stuff like this.  They mark sleeping and feeding areas and waterholes. Ã Homo sapiens [Human] See the separate article "Pig-human Hybrids." Phacochoerus aethiopicus See also Melletti and Meijaard (2017, p. 163). Ã Hylochoerus rimator [West African Forest Pig] In most taxonomies, three African pig populations meinertzhageni, of eastern Africa, rimator, of central Africa, and ivoriensis, of western Africa, have been lumped as subspecies of H. meinertzhageni. Contact occurs where introduced Eurasian wild pigs have become established in Burkina Faso, Gabon and, probably, Dem. Dzo. Articles from Britannica Encyclopedias for elementary and high school students. These populations are also potentially seriously threatened by "genetic contamination" through interbreeding with free-ranging domestic and feral pigs." Males have four warts, two large "Peccaries and pigs are distant relatives, but have many differences," explains Emily Kornmuller, mammalogy and ornithology Keeper at Tucson's Arizona-Sonora Desert Museum , in an email interview. S. scrofa is feral throughout much of S. barbatusâs range (Malay Peninsula, Sumatra, Borneo, and adjacent islands).

They also have very distinct tusks, which reach a length of 25.5 to 63.5 centimetres (10 to 25 inches) in the males, but are always smaller in the females. See note immediately preceding Sus barbatus. Chromosome analysis of one of the surviving males has confirmed it was indeed a hybrid between domestic pig and a babirusa.
