Conteúdo: | The study was undertaken to characterize breed features, reproductive performance, breeding practice, breed selection criteria and herd replacement in Ethiopian swine production systems. A total of 66 swine farms were selected in six major towns to collect quantitative and qualitative data on the studied parameters. A multi-stage sampling procedure was employed to select sampling areas and respondents. A standardized questionnaire was used to collect the data using person to person interview. Data were analyzed using appropriate statistical procedures of SAS and SPSS software packages. The study revealed that Ethiopian swine breeds had diverse coat colors where white coat color was the predominant one. Average reproductive performances of swine herds for age at first puberty, litter size and gestation length were ranged from 9 ? 10 (months), 8 ? 10 (piglets per farrowing) and 3 to 3.5 (months), respectively. None of these reproductive performances were significant (P>0.05) across the three scales of production. About 76 ? 86% of the total interviewed swine producers did select sires and dams for breeding. Dams section was mainly based on health status, body conformation and mothering ability; whereas, sires selection was based on health status, body conformation and coat color. Findings of this study can support the development of breeding strategies aiming to improve Ethiopian swine production and productivity.
