Relative resistance of Menz and Washera sheep breeds to artificial infection with Haemonchus contortus in the highlands of Ethiopia
The aim of this study was to evaluate the relative resistance of Menz and Washera sheep breeds to artificial infection with Haemonchus contortus. The challenge trial was conducted at the Debre Berhan Agricultural Research ...
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 ...
System dynamics modeling in designing breeding schemes: The case of Menz sheep in Ethiopian highlands
A comprehensive dynamic simulation model was developed to describe a community-based breeding program for the Menz sheep population of Ethiopia. Selection of male and female animals based on their own and maternal performance ...
Genetics of adaptation in domestic farm animals: A review
This review summarizes available information on genetics of adaptation in major livestock species focusing on small ruminants. Adaptation to humans and consequences of domestication on predator aversion, mechanisms of ...
The African Goat Improvement Network: a scientific group empowering smallholder farmers
The African Goat Improvement Network (AGIN) is a collaborative group of scientists focused on genetic improvement of goats in small holder communities across the African continent. The group emerged from a series of workshops ...
The Goat and Goat Production Systems of Small-Scale Producers of the Comarca Lagunera, in Northern Mexico
A baseline study was conducted in the Comarca Lagunera in the North of Mexico to evaluate the potential for implementation of a breeding program. A questionnaire was applied to 64 producers to document the production system. ...
Community-based sheep breeding programs generated substantial genetic gains and socioeconomic benefits
Community-based breeding programs (CBBPs) for small ruminants have been suggested as alternatives to centralised, government-controlled breeding schemes which have been implemented in many developing countries. An innovative ...
Herd management and breeding practices of sheep owners in a mixed crop-livestock and a pastoral system of Ethiopia
An exploratory survey was undertaken to understand sheep production system, breeding practices and selection criteria for Ethiopian Menz and Afar sheep breeds in their home tract as a step towards developing sustainable ...
Community based sheep breeding programs: Tapping into indigenous knowledge
A study was undertaken to understand local knowledge and practices of communities in animal management as a step in designing and
implementation of communitybased
breeding programs for four local breeds (Afar, Bonga, Horro ...
Community-based alternative breeding plans for indigenous sheep breeds in four agro-ecological zones of Ethiopia
Based on the results of participatory approaches to define traits in the breeding objectives, four scenarios of ram selection and ram use were compared via deterministic modelling of breeding plans for community-based sheep ...
