The most of local sheep breeders in Indonesia are fat-tailed sheep called Domba Ekor Gemuk (DEG) and thin-tailed sheep called Domba Ekor Tipis (DET). The morphometric characterization of livestock is important for planning improvement, sustainable utilization, conservation strategies, and breeding programs. This study compares the phenotypic characters based on qualitative and quantitative traits between DEG and DET in Dampit District, Malang Regency. The data obtained will be useful for genetic improvement development programs and the selection of superior broodstock for breeding. Using 60 rams (30 DEG and 30 DET) range 1-2 years old in Dampit District, Malang Regency, East Java, Indonesia. Data were collected by observing, measuring, and following the data farmers recorded.
