The estimation of Genetic Distance and Discriminant Variables 011 Local Goat Breeds Using Morphological Analyses

Abstract

The aim of this research was to estimate the genetic  distance and discriminant  variables between local  goat breeds,  and also to know the accuration   of classifying  of local goat breeds by morphological analysis.  The number  ofsamples examined  for Etawah grade, Jawarandu, Kejobong, and Kacang goats were 10,  11,  7 and 14,  respectively.   Zoometrical  variables studied were body weight, body length, wither height, chest circumference,  chest depth, chest wide, hip height, hip depth, ear length, and tail length.  The SAS ( 1990) was applied  for discriminant  and canonical  analysis. Results showed that :  (I)  The smallest  genetic distance  was between  the Kejobong goat and the Jawarandu  goat and was 11,32;   While the largest  genetic distance was between the Etawah grade goat and the Kacang goat and was 313,95;   (2) Results from distribution  mapping produced  by canonical analysis showed that almost all groups breed clearly separate,  except partly Kejobong  goat and Jawarandu  goat close together;  (3) Ear length  and tail length were the best discriminator  for the first canonical  variate;  and tail  length, hip  height and ear length  were the best discriminator   for the second one; (4) The higest similarity  individual  inside the group was obtained  from Etawah grade, Jawarandu,  and Kacang  goat, and was I 00 %.  The group Kejobong  goat was mixed  by J awarandu goat with 14,29 %; (5) Breeds resulted high accuracy as indicated by the low probability of errorneous discrimination.   The accuracy  accounted  96,43 %, the rate misclassification  3,57 %.
