The study was conducted in Lode Hetosa, Lemmu Bilbilo, and Diksiis districts of the East Arsi zone of Oromia Regional State to undertake phenotypic characterization of indigenous sheep types. Multistage purposive and random sampling was employed as sampling techniques. Body weight, linear body measurements, and qualitative data were taken and observed on 576 mature sheep (500 females and 76 male sheep). In all districts, sheep were primarily kept for income generation. The major available feeds for the wet and dry seasons were natural pasture and crop residues, respectively. Disease was ranked as the first pertinent constraint for sheep production in all study districts. Most East Arsi sheep populations were characterised by a plain coat colour pattern accompanied by various coat colour types (plain brown, light red, and red, and brown + white coat colour) and medium- length hair. Body weight and heart girth were found to be positively correlated in both sexes. The regression analysis showed that body weight, in most of the cases, could be predicted with a higher level of accuracy from more than one independent variable or in combination with various variables. Generally, no significant differences were observed among the sheep types found in the study districts, indicating that they are the same breed.
