Maximizing the number of ofspring born per female is a key functionality trait in commercial- and/or subsistence-oriented
livestock enterprises. Although the number of ofspring born is closely associated with female fertility and reproductive success...

Ethiopia has a large and diverse population of small ruminants, which contribute
substantially to the livelihood and income of the rural poor and the country at large.
However, the sector faces a number of challenges. Productivity per animal and...

On station small ruminant researches in Ethiopia were ineffective due to various factors. As alternative, community based breeding program (CBBP) has emerged. In the current CBBPs, sires’ side selection only (SN1) was practiced. The objective of the...

In this study, expected genetic progress and economic benefits from implementing three community-based breeding programs for sheep (CBBP) out- and upscaling strategies were investigated. Strategy 1 is to replicate average existing CBBPs, strategy 2...

Community-based sheep breeding programs (CBBPs) were established in Ethiopia since 2010. Improved rams from CBBPs need to be disseminated. However, there is a risk of transmitting reproductive diseases to other community flocks. To investigate this a...

Gastrointestinal nematodes (GIN) remain one of the main health and production constraints of sheep globally. Considering alternatives to anthelmintics in control of GIN of sheep has become important mainly due to development of anthelmintic...

African livestock breeds are numerous and diverse, and typically well adapted to the harsh environment conditions under which they perform. They have been used over centuries to provide livelihoods as well as food and nutritional security. However...

Assessments of production parameters and flock productivity were made in three indigenous goat breeds of Ethiopia. The goat breeds included Abergelle (AB), Central Highland (CH) and Woyto-Guji (WG). Objectives of this work were to estimate production...

This article aims at identifying factors that determine market prices of goats and analyse potential mechanisms by which smallholder goat producers could maximize their benefits. Data on 357 farm households and 2103 goat transactions were collected...

Lungworms are important parasitic nematodes of small ruminants that colonize the lower respiratory tract and cause high morbidity and economic loss throughout the world. This systematic review was conducted with the aim of estimating the pooled...

Genetic parameters and genetic trends for growth, reproduction, milk production and composition traits were estimated for Syrian (S) and Turkish (T) Awassi sheep and their crosses maintained at the International Center for Agricultural Research in...

We generated epidemiological information on the prevalence of nematode parasites and possible resistance/resilience of goats in three areas, Bati, Shinille, and Borana, of Ethiopia. A total of 350 breeding does were randomly selected and monitored...

This study aimed at identifying Sheko cattle keepers' preferences by way of phenotypic ranking and hypothetical choice experiment in their habitat in order to define the indigenous selection criteria. The ranking experiment report was based on 15...
