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...

The study investigated, for cycling sheep, synchronizing protocols simultaneously to the standard “P” protocol using progestogens priming with intravaginal devices and gonadotropin. In November 2014, 90 adult Menz ewes were assigned to either the “P”...

An exploratory survey was undertaken in Doyogena district of Southern Nation Nationalities Peoples region of Ethiopia to understand the sheep production system, the breeding practices, selection criteria and sheep production constraints in order to...

Description of the physical characteristics of livestock breeds is very important for developing a breeding strategy in a particular production system. Doyogena sheep are among the potential breeds of Ethiopia reared in the mixed perennial crop and...

The present study was conducted to justify that keeping birth weight (BWT) records have little or no significance in genetic improvements of market or adult weights of small ruminants while implementation of community based breeding program (CBBP)....

Domestic goats in Syria may provide an interesting source of genetic variability due to its proximity to the centers of domestication. This study aimed to assess the morphological variation, genetic diversity and population substructure of the Syrian...

The objective of this review paper is to examine whether or not sheep crossbreeding is a feasible option to improve indigenous sheep breeds in developing countries using Ethiopian case as example. The paper reviewed and discussed the history of...

The objective of this study was to characterize Bati, Borena and Short-eared Somali goat populations kept under traditional management systems. The survey conducted in three locations; namely Bati, Borena and Siti (the previous Shinille) representing...

A simulation study was conducted to optimize a cooperative village-based
sheep breeding scheme for Menz sheep of Ethiopia. Genetic gains and
profits were estimated under nine levels of farmers’ participation and
three scenarios of controlled breeding...

Village- and central nucleus-based schemes were simulated and evaluated
for their relative bio-economic efficiencies, using Ethiopia’s Menz sheep as
example. The schemes were: village-based 2-tier (Scheme-1) and 1-tier
(Scheme-2) cooperative village...

Pedigree recording and genetic selection in village flocks of smallholder farmers have been deemed infeasible by researchers and development workers. This is mainly due to the difficulty of sire identification under uncontrolled village breeding...

A community-based sheep breeding program has been implemented in the highlands ofEthiopia to improve the body weight of Menz sheep. It is important to evaluate the potentialconsequences of such a breeding strategy on herd dynamics. For this purpose,...

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 and Menz) in four sites in...

The genetic trends in fitness (inbreeding, fertility and survival) of a closed nucleus flock of Menz sheep under
selection during ten years for increased body weight were investigated to evaluate the consequences of selection
for body weight on...

The influence of non-genetic factors on lamb survivability at various ages up to 360 days was studied under village management condition in Jimma, Ethiopia. The overall least squares means of lamb survival rate was 89.0 at 0-60, 81.5 at 0-120 and 50...
