Abstract

This objectives of the present study were to estimate variation of phenotypic values and genetic distance of Garut sheep and crossbreed of Garut. A total of 725 Garut sheep (357 ewes and 368rams) were used in this study sheep were consisted of 74 Margawai crossbred sheep (40 ewes and 34 rams), 81 fighting type sheep from Wanaraja (B) (37 ewes and 44 rams) , 74 meat type sheep from Wanaraja (W) (50 ewes and 24 rams), 110 fighting type from Sukawening (A) (50 ewes and 60 rams), 63 meat type from Sukawening (S) (40 ewes and 23 rams), 63 fighting type from Ciomas (C) (20 ewes and 43 rams), 189 crossbreed type from Jonggol (J) (68 ewes and 121 rams) and 71 meat type from TDS or Cinagara (T) (52 ewes and 19 rams). Body dimension studied were body weight, body length, wither height, chest width, chest depth, chest circumference, tail length, tail width. Data obtained were analyzed by simple discriminant and canonical analysis with SAS package program version 7.0 and MEGA 2 to get the construction of phenogram tree. The result showed that Margawati sheep had given more variation phenotype value in Garut sheep in district and out district of Garut. The lenght of genetics distance between fighting Wanaraja and Jonggol sheep was 14,46 while the closed genetics distance between fighting Wanaraja and fighting Sukawening was 1,53 and same as the genetic distance between fighting Wanaraja and Margawati sheep. The tail width, wither height, body length and chest circumferene were variables to determine the different groups of Garut sheep and crossbreed. Keywords: Garut Sheep, Phenotypic Variation, Genetic Distance, Body Measurement.
