Sheko cattle owners usually have limited control over breeding practice of their cattle. This is because they allot fractions of their time and resources in controlling breeding practices. Therefore, most often mating is natural and uncontrolled and this would result in non-descript herd structur...

Economic comparisons among Ethiopian Boran and their crosses with HolsteinFriesian were made in the central highlands of Ethiopia. Data collected fromexperimental dairy cattle herds of the International Livestock Research Institute(ILRI) at the Debre Zeit Research Station, Ethiopia were used. The...

Initial and peak milk yield, days to peak milk yield and persistency index (PI) of indigenous and crossbred cows were determined to characterized their lactation curve. The study was based on existing data in the Bako Agricultural Research Center and Debre Zeit Research Station. The overall mean ...

This study was conducted to identify and describe the cattle genetic resources in South and North Wollo zones of Amhara Region, North Eastern Ethiopia based on their descriptive morphological characteristics. A total of seven sampling sites were selected based on the information obtained about th...

Postpartum anoestrus interval (PPAI) and estrus activity measured as probability of getting acow in estrus within 42 (PPAI42), 63 (PPAI63) and 84 (PPAI84) days postpartum in indigenousand crossbred cows were studied using data from Bako Agricultural Research Center. PPAI wasanalyzed using the Gen...

This paper presents a framework for Community Based Management (CBM) of indigenous cattle in Dano district of West Shoa Zone in Central Ethiopia. Results of multi-disciplinary research conducted over three years served as a foundation for this framework. It outlines the essential activities and c...

The study was conducted to estimate model parameters of Incomplete Gamma (IG) (b=1) and Inverse Polynomial ¢P) functions of a lactation curve and the models lactation yield prediction potential based on milk data from Bako Agricultural Research centre and Debre Zeit Research Station. The models w...

Five lactation curve models were compared for their fitness to milk data of indigenous and crossbred cows using data from Bako Agricultural Research Center and Debre Zeit Research Station. The fit of the models was compared using the model R2 value. The overall mean R2 value was 81.5 ± 0.12% and ...
