Abstract

Batur and Wonosobo sheep are two Indonesian indigenous sheep breeds from Central Java Province, Indonesia. This study aimed to describe and discriminate the morphostructure of Batur sheep and Wonosobo sheep with body measurements and body indices.

Fourteen body measurements and nine body indices were measured from 37 Batur and 83 Wonosobo sheep. Two statistical methods of factor and discriminant analyses were computed with SPSS 25.0 program to describe the sheep's morphostructure and characterization.

The factor analysis in body measurements was obtained three principal components (PCs) that explain about 76.58% (Wonosobo sheep) and 73.51% (Batur sheep) of the total variance in animals’ morphostructure. Meanwhile, the factor analysis in body indices was obtained on three PCs that explain about 79.16% (Batur sheep) and 95.57% (Wonosobo sheep) of the total variance in animals’ morphostructure. About 95.2% of Wonosobo sheep and 92.7% of Batur sheep can be classified with body measurements (RW, SW, EL, EW, RH and TL). Meanwhile, about 75.7% of Batur sheep and 80.7% of Wonosobo sheep can be classified with body indices (TI and CI). In conclusion, Batur and Wonosobo sheep can be accurately characterized by their body measurements.
