About 60 Black Head Somali rams were used in 21-month experiment period (18 months for growth to maturity and 3 months for fattening) to investigate the effect of age at castration on growth to maturity, fattening capability after maturity and market value of fattened mature rams which had been c...

Mortality was studied in relation to birth weight (BWT) and postpartum age in 3083 Horro lambs born over 15 years at Bako Research Center, IAR. Pre-weaning mortality rose with declining BWT (log y = 2.20- 0.35X; r = 0.9981), but the influence after weaning was less pronounced and linear (y = 23.7...

Ethiopia has a diverse sheep population, numbering 23.6 million, in parallel with its diverse ecology, production systems and communities. A comprehensive phenotypic and genetic characterization of Ethiopian sheep populations was initiated in 2005 to provide a nationwide framework for the managem...

Livestock characterization projects in developing regions are characterized by a mere physical description of traditionally recognized populations or a purely academic genetic description of populations. However, characterization of livestock resources is meant to serve the purpose of developing ...

Designing breeding schemes suitable for smallholder livestock production systems in developing regions has hitherto been a challenge. The suggested schemes either do not address farmers’ breeding goals (centralized station-based nucleus schemes) or yield slow genetic progress (village-based schem...

Part I of this working paper classifies small ruminant sub-systems in the mixed crop livestock system in Ethiopia. In Part II, important determinants of small ruminant productivity and producers’ input use and marketing strategies were analysed across the six small ruminant sub-systems identified...
