Ayalew, W.[Ongoing research and development efforts in sheep genetic improvement (genetic gains)]Ongoing research and development efforts in sheep genetic improvement (genetic gains)

Sheko is the only surviving taurine of the Abyssinian region, and is in danger ofextinction mainly due to interbreeding with neighboring Zebu breeds and scarcityof pure Sheko breeding bulls. This study was undertaken to study current statusof Sheko cattle breed and husbandry practices in southwes...

Wollny, C.B.A.Drucker, A.G.Ayalew, W.Koudande, O.D.Dossa, H.Kassie, Girma T.Gizachew, L.Kaufmann, B.Haro, G.[Improving the livelihoods of poor livestock keepers through community based management of indigenous farm animal genetic resources in Africa]Improving the livelihoods of poor livestock keepers through community based management of indigenous farm animal genetic resources in Africa

Conventional productivity evaluation criteria are inadequate to evaluate subsistence livestock production, because: (1) they fail to capture non-marketable benefits of the livestock; and (2) the core concept of a single limiting input is inappropriate to subsistence production, as multiple limiti...


Ayalew, W.King, J.M.Bruns, E.Rischkowsky, Barbara A.[Economic evaluation of smallholder subsistence livestock production: Lessons from an Ethiopian goat development program]Economic evaluation of smallholder subsistence livestock production: Lessons from an Ethiopian goat development program

Crossbreeding of goats in traditional subsistence flocks had been promoted in selected villages of eastern Ethiopian highlands as a means to quick genetic progress based on the thesis that crossbreeding can increase the net contribution of goats. Observations on flock dynamics patterns of smallho...

Ayalew, W.[Do smallholder farmers benefit more from crossbred (Somali × Anglo-Nubian) than from indigenous goats?]Do smallholder farmers benefit more from crossbred (Somali × Anglo-Nubian) than from indigenous goats?

Ayalew, W.Getahun, E.Tibbo, MarkosMamo, Y.Rege, J.E.O.[Current state of knowledge on characterisation of farm animal genetic resources in Ethiopia]Current state of knowledge on characterisation of farm animal genetic resources in Ethiopia

The rearing of indigenous chickens is an integral part of the smallholder farming system in the tropics, where they are kept by the rural poor to fulfil multiple functions. Their special adaptation to environmental stresses and poor husbandry practices has made them the choice of breed for smallh...


Dessie, TadelleTaye, T.Dana, N.Ayalew, W.Hanotte, Olivier H.[Current state of knowledge on phenotypic characteristics of indigenous chickens in the tropics]Current state of knowledge on phenotypic characteristics of indigenous chickens in the tropics

Breed additive and non-additive effects, and heritabilities of birth weight (BWT), weaning weight (WWT), 6 months weight (SMWT), yearling weight (YWT), eighteen months weight (EWT), 2 years weight (TWT) and average daily weight gain from birth to 6 months (ADG1) and from 6 months to 2 years (ADG2...


Haile, AynalemJoshi, B.K.Ayalew, W.Tegegne, T.Singh, A.[Genetic evaluation of Ethiopian Boran cattle and their crosses with Holstein Friesian for growth performance in central Ethiopia]Genetic evaluation of Ethiopian Boran cattle and their crosses with Holstein Friesian for growth performance in central Ethiopia

Breed additive and non-additive effects, and genetic parameters of milk fat, protein, solids not fat (SNF) and total solids (TS) percents, were estimated in Ethiopian Boran cattle and their crosses with Friesian in central Ethiopia. Ethiopian Boran cattle were consistently superior (P<0.01) to th...
