Genetic diversity of the indigenous cattle of Kenya, Uganda, Ethiopia and Tanzania using high-density SNP data. The indigenous cattle make a significant contribution to the livelihood of many communities in Ethiopia, Tanzania and other countries in eastern Africa. Here, we identify the genetic st...

Cost-effective genotyping of livestock species can be done through a process which involves genotyping part of the population using a high density (HD) panel and the remainder with a lower density panel and then use imputation to infer the missing genotypes that are not included on the low densit...

The Kuri is a rare, little known breed of cattle of the Hamitic Longhorn (Bos taurus longifrons) type which is found on the islands and shores of Lake Chad Basin in the area covering the common borders of Cameroon, Chad, Niger and Nigeria. It is taller and more massive than its longhorn counterpa...

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...

Thirty-two goat flocks belonging to 45 farmers and raised under village conditions in the Ganawuri area of the subhumid zone of Nigeria were monitored every 2 weeks for 30 months to determine productivity under village conditions. Records collected on kids included birth weight, birth type, body ...

The genetic history of African cattle pastoralism is controversial and poorly understood. We reveal the genetic signatures of its origins, secondary movements, and differentiation through the study of 15 microsatellite loci in 50 indigenous cattle breeds spanning the present cattle distribution i...

The Menz and Horro highland sheep breeds are being evaluated at the ILCA Debre Birhan research station in Ethiopia for between-and within-breed genetic variation for resistance to internal parasites. The experimental design involve mating, for each breed, 150 ewes with 10 rams to lamb at the begi...

Sub-Saharan Africa is rich in animal biodiversity. Over 95 percent of the continent's domestic ruminants are indigenous. In Africa, indigenous livestock breeds support the majority of smallholder rural farmers for whom these genetic resources are important for improved nutrition, income and as in...
