Multivariate analysis on cranium measurements of three breeds of goat in central Java

The purposes of this study were to 1) identify the size and shape of cranium of three breeds of central java local goats (kejobong,kacang and ettawa grade),2) examine the effectiveness of multivariate analysis of cranial measurement and 3) estimate genetic distance among three local breeds of goat. the material used was cranium from female kejobong,kacang and ettawa grade goats,aged for about 4 years (determined on the basis based on eruption of teeth),the number of specimens were 30; 10 and 10,respectively. twenty seven cranial measurements used to data observed,multivariate analysis of glm,candisc,princomp and discrim were used to analysis all data observed. upgma of mega 5 was used to illustrate the distance among breeds. results showed that ettawa grade tended to show the largest size,followed by kejobong and kacang goats. kejobong goat showed small cranium size with large cranium shape. different things was found in kacang goats in which cranium size and cranium shape are relatively small. kacang breed showed the smaller size (principal component i or pc-1 = -2) compared to ettawa grade (pc-i = 3) and kejobong goat (pc-i = -1). analysis for classifying three breeds of local goat resulted in high accuracy (100%) as indicated by 0% of erroneous level (0%). kejobong goat was close to in the genetic relationship to kacang goat compared to ettawa grade goat. © 2013 diponegoro university. all rights reserved.
