Development of improved vaccine and diagnostic-based disease control strategies has benefited considerably from advances in biotechnology, particularly those relating to recombinant DNA technology. Efficiency of the vaccine development process has been increased at all levels, from the analysis o...

On-station characterisation of indigenous Menz (n = 1639) and Horro (n = 1135) sheep of Ethiopia in the central highlands of the country was undertaken between 1992 and 1997 at the Debre Berhan Research Station of the International Livestock Research Institute (ILRI) to study the phenotypic chara...

A total of 146 Menz and Horro lambs of both sexes were serially slaughtered and dissected at 5 different stages of growth (i.e. at 1, 3, 6, 9 and 12 months of age) to define the pattern of growth and partitioning of fat among body depots of indigenous Ethiopian Menz and Horro sheep breeds. The GL...

Genetic markers are being used by scientists worldwide in both animal and plant related breeding and Development efforts. The International Livestock Research Institute (ILRI) is a new institute formed in January 1995 by the amalgamation of the former ILCA (International Livestock Centre for Afri...

Data collected on 3256 lambs born to Horro and Menz breed ewes single-sire mated to 71 rams at the International Livestock research Institute (ILRI) Debre Berhan station between September 1992 and June 1996 were analysed for rates of survival and growth from birth to weaning. A significantly lowe...
