For the purpose of investigating classification and genealogical relationships in the different types of the native cattle in eastern Asia, principal component analysis was carried out, using nine body-measurements of three wild Banteng (Bos banteng) in Indonesia and 676 animals in sixteen kinds of the native cattle in eastern Asia, i. e.: the Mishima and Kuchinoshima in Japan; the Taiwan yellow-cattle; the Thai native; the Kedah-Kelantan in Malaysia; the Cebu native, Palawan native, Ilocos, Iloilo and Batangas in the Philippines; the Grati, Aceh, Padang native, Madura, Bali and Ongole breeds in Indonesia; and additionally the Hainan and the Sindhi breed reported by Motohashi and Yanagawa, respectively. The results were summarized as follows: (1) The first principal component (size factor) strongly contributed to the separation of the Grati and Ongole breeds from the other kinds of native cattle. (2) On the second principal component (shape factor), the Mishima and the Kuchinoshima, believed to be a primigeniustype cattle, were greatly separated from the Ongole and Sindhi breeds, which are typical Indian zebu-type cattle. (3) The Bali, believed to be a domesticated form of the Banteng, and the wild Banteng were separated from the others mainly by the third principal component (unknown factors). (4) In the two charts constructed for the first and the second principal components and for the second and the third principal components, the group of yellow-cattle in Southeast Asia, including the Hainan, showed considerable similarity. However, the Batangas, Palawan native and Taiwan yellow-cattle were somewhat larger than the other yellow-cattle in the size factor. Furthermore, the Batangas, Palawan native and Ilocos in the Philippines were separated slightly from the yellow-cattle in Sumatra island, the Malay peninsula and Thailand, on the shape factor. (5) The values of the body-measurements of the wild Banteng were larger than those of the Bali, but they resembled each other in shape. In view of this analysis of bodyconformation it can be suggested that the native cattle in eastern Asia are separated into four groups, i. e.: primigenius-type cattle, Indian zebu-type cattle, the yellow-cattle group, and the Bali and the Banteng.
