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 ...
Phenotypic, Genomic and Physiological Basis of Fecundity Traits in Bonga Sheep of Ethiopia
Three interrelated investigations were carried out with the objectives of estimating genetic
parameters and trends of selection for Age at First Lambing (AFL), Lambing Interval (LI) and
Litter size (LS); understanding the ...
Genetic and non-genetic effect on fertility trait of different ram breeds reared in the highland of North-Shewa, Ethiopia
The aim was to investigate genetic and non-genetic factors influencing fertility of rams. The fertility study encompassed 155 rams of different breed mated to 14,357 ewes over several years, seasons, locations and genotypes. ...
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 ...
Decades of Faba Bean (Vicia faba L.) Breeding for Better Grain Yield and Seed Size has Inadvertently Reduced G × E Interaction and Increased Inter-Temporal Performance Stability
Thirteen faba bean varieties including 11 released between 1977 and 2007 and two promising genotypes were evaluated at seven contrasting environments in the central and southeastern highlands of Ethiopia during the main ...
Gastrointestinal nematode infection in small ruminants in Ethiopia: A systematic review and meta-analysis
Gastrointestinal (GI) nematode infections are a major health challenge affecting productive and reproductive performance of sheep and goats in Ethiopia. However, there is no comprehensive summary on the occurrence and ...
Lungworm infection in small ruminants in Ethiopia: Systematic review and meta-analysis
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 ...
Systematic review and meta-analysis of metacestodes prevalence in small ruminants in Ethiopia
Metacestodes, the larval stages of canid cestode parasites, are among the causes of morbidity, mortality and financial losses in small ruminants in Ethiopia as a result of organ and carcass condemnation at slaughter. Several ...
Genetic and economic evaluation of alternative breeding scenarios for community based productivity improvements of three indigenous goat breeds in Ethiopia
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 ...
Identification of smallholder farmers and pastoralists’ preferences for sheep breeding traits: choice model approach
Identification of breeding objective traits pertinent to specific production environments with the involvement of target beneficiaries is crucial to the success of a breed improvement program. A choice experiment was ...
