The Estimation of Genetic Distance on Java Cattle and Classifying of Cattle Breeds in Indonesia by MorphometricalAnalysis of Mandible

Abstract

Java cattle is an endogenous breed, and they have posibility comparative advantage. The research of Java cattle, especially for genetic's improvement are still rare. Indonesian native catties have genetic relationship among them. The objectives of this researchwas  to estimate genetic distance on Java cattle and cattle breeds in Indonesia, and also to know the accuration of classifying of cattle breeds by norphometrical analysis of mandible. The number of specimens examined for Java, OngoleCrossbred,  Madura, and Bali cattle were 19, 38, 12 and 17, respectively.They were collected from the slaughter hauses in Brebes, Semarang, Bangkalan, Dendasar and Jakarta respectively. Mean-while, 14 specimen of banteng weere obtained from the Bogor Zoological Muzeum. Each spe cimen collected was measured for I 5 mandibular measurementent. The SAS (1990) was applied for multivariate analysis approaches. Multi• variate analysis performed using Discriminant Analysis. Results showed that (I)  Jawa cattle was nearer in the genetic relationship to Madura, subsewuently followed by Bali and Ongoloe Crossbred. Banteng was the farthest to a both Madura and Ongole Crossbread: 2) breeds resulted hiht accuracy as indiracy as indicated by the low probability of errorneous discrimination. The accuracy accounted 95,29 %. The rate misclassification was 4, I 7 %.
