The blood relationship among Japanese wild boar (Sus vittatus japonica) and, Yorkshire (Sus scrofa domesticus) and their hybrids was studied by means of precipitin reaction.The results obtained are summarized as follows:The absorbed antiserum against the wild boar which was exhausted completely with blood serum of a Yorkshire pig or one in F1 generation did not react against blood serum of the wild boar or any kind of an animal.But the situation was not the same when the conditions were made reverse.The absorbed anti-Yorkshire serum exhausted with wild boar serum, reacted upon Yorkshire of F1 serum, and Yorkshire serum showed stronger reaction than F1 serum.Similarly, the absorbed anti-hybrid serum exhausted with wild boar serum, gave the same degree of reaction upon Yorkshire and F1 serum, but the absorbed anti-hybrid serum exhausted with Yorkshire serum did not react upon all kinds of blood serum.Hence, it is presumed that the domestic pig possesses a specific serum protein in blood serun in addition to one contained in wild boar serum. Hybrids between the domestic pig and wild hoahave all the serum components which are containe in the domestic pig, and are considered to be in the middle between the parent breeds.
