Abstract: This study was conducted to estimate non-genetic factors and genetic parameters for birth weight and reproduction traits of pure Jersey dairy cattle at Adea Berga Research Station. A total of 11,794 pure Jersey dairy cattle performance records which were collected from 1986 to 2019 was used for the study. The General Linear Model (GLM) procedures of SAS software were used to determine the effects of non-genetic factors. Genetic parameters and variance components were estimated by A...

Three PA’s from each district, a total of Six PA (Huluka, Kawa, Barchota, Benti, Kobo and...
Abstract: The study was conducted in Bako Tibe and Dano districts, Oromia, Ethiopia; from January 2016 to January 2018 with the objectives to identify indigenous chicken husbandry and breeding practices and to evaluate the performance of exotic( Sasso, Sasso-RIR and Koekoek) and improved Horro chicken breeds under farmer’s management conditions. Field study and data collections were carried out through a semi-structured questionnaire, focus group discussions with key informants, observatio...
Abstract: The study was conducted on 120 randomly selected households for characterization of chicken production systems and at on-farm in 144 purposively selected households to comparative performance of Sasso, Sasso-RIR and Improved Horro in Adami Tullu and Dugda districts. The average chicken flock size in the study area was 11.8. The main source of foundation flock was inherited. Majority of households had no experiences of rearing exotic chickens. Body weight and feather colour for cock...
