Orenge, C.O.Munga, L.Kimwele, C.N.Kemp, Stephen J.Korol, A.Gibson, John P.Hanotte, Olivier H.Soller, M.[Trypanotolerance in N’Dama x Boran crosses under natural trypanosome challenge: Effect of test-year environment, gender, and breed composition]Trypanotolerance in N’Dama x Boran crosses under natural trypanosome challenge: Effect of test-year environment, gender, and breed composition

Despite the wide range of observed phenotypic diversities and adaptation to different ecological conditions, little has been studied regarding the genetics of adaptation in the genome of indigenous cattle breeds of developing countries. Here, we investigated the linkage disequilibrium (LD) and id...

The study was carried out in June 2010 in selected villages of Amhara region of Ethiopia, representing three levels of market quality (high, medium and low), with the general objective of developing a systematic understanding of the links between market opportunities and productivity increases in...

he survey was carried out in Horro district of Horro Guduru zone, west part of Ethiopia. The objectives of the survey were: to describe cattle production system, trait preferences, breeding practices, and constraints in utilization of the breed and to use the information generated as baseline dat...

This study was conducted to evaluate reproductive performance of crossbred cows and to identify potential constraints of dairying under small and medium scale farmers’ management in urban and peri-urban dairying of mid rift valley, Ethiopia. The data was collected through questionnaire from 120 s...

Climate change and variability can severely constrain the productivity of pastoral herds by reducing water availability, forage production and quality, and hence the carrying capacity of rangelands. In particular, the risk of heavy livestock losses suffered during recurrent severe droughts associ...

The preservation for future use of endemic ruminant livestock (ERL) depends on how these breeds are perceived by smallholders in relation to their Sahelian counterparts with a larger frame. These indigenous livestock breeds have unique genetic traits that are important to smallholders’ livelihood...

Peptide-major histocompatibility complex (p-MHC) class I tetramer complexes have facilitated the early detection and functional characterisation of epitope specific CD8+ cytotoxic T lymphocytes (CTL). Here, we report on the generation of seven recombinant bovine leukocyte antigens (BoLA) and reco...
