Field synchronization of Ethiopian Highland sheep for fixed time artificial insemination: improvement of conception rate with a double injection of prostaglandin at 11 days
The study investigated, for fixed time artificially inseminated (AI) Menz ewes in field trials, the reproductive
performance of prostaglandin-based treatments simultaneously to the standard ‘P4+eCG’ protocol. A total
of ...
Participatory identification of breeding objective traits and selection criteria for indigenous goat of the pastoral communities in Ethiopia
Structured questionnaire, own-flock rankings and group discussions were undertaken to assess goat breeding practices and to identify traits of interest for genetic improvement of pastoral goats. Four pastoral villages in ...
Evaluation of increased feed supply and different fattening strategies for an Ethiopian sheep population by system dynamics modelling
Context: The productivity of Ethiopian smallholder farms is considered to be low owing to different factors such as feed shortage, lack of breeding strategies, disease prevalence and missing marketing strategies.
Aim: The ...
Efficiency of artificial insemination as a scaling tool of sheep breeding schemes
The study investigated, for artificially-inseminated (AI) Menz ewes, the reproductive performance of prostaglandin-based treatments simultaneously to the standard “P4+eCG” protocol using progestogens priming with intravaginal ...
Establishment of breeders’ cooperatives in the priority country CBBP sites
Background
Ethiopia priority country project is a 3-year project designed to consolidate the individual pilot
interventions CRP research has been implementing since 2012 and translate that into a pilot
integrated packages. ...
Upscaling of community-based breeding programs in Ethiopia: 2020 report
Background
In Ethiopia pilot community-based breeding programs (CBBPs) have been designed and
implemented since 2010 by a team of researchers from the International Center for
Agricultural Research in the Dry Areas, the ...
Increased number of large non-atretic follicles and codominance effects account for high litter sizes in Bonga sheep
To understand the ovarian basis for prolificacy of Bonga sheep, a total of 31 ewes were selected based on litter size (LS) records and divided into two groups: High Prolificacy (HP) (n = 20) with LS ≥ 2 and Low Prolificacy ...
Field guideline for low-cost artificial insemination of sheep and goats in Ethiopia
These guidelines are elaborated in the specific context in which CBBP’s are run in Ethiopia. Following an overview of the anatomical and physiological aspects of reproduction in sheep and goats that are important to AI, ...
A genetic database tool for data capture in small ruminant community-based breeding programs
Genetic improvement on local breeds kept by small farmers in developing countries is
challenging. Even though good pedigree and performance recording is crucial and an
important component of breeding programs, it remain ...
