Background: The history of African indigenous cattle and their adaptation to environmental and human selection
pressure is at the root of their remarkable diversity. Characterization of this diversity is an essential step towards
understanding the genomic basis of productivity and adaptation to s...
Gastrointestinal (GI) parasitic infection is the main health constraint for small ruminant production, causing loss of weight and/or death. Red Maasai sheep have adapted to a tropical environment where extreme parasite exposure is a constant, especially with highly pathogenic Haemonchus contortus...

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...

We describe satellite DNA variation that detects hybridization of Bos indicus (Zebu or indicine cattle) and Bos taurus (taurine cattle) in African cattle populations. On southern blots hybridized to a satellite III probe, relative intensities of Hinf1 fragments correlated with the taurine-zebu co...

Information is presented on the frequency of the Msp I (-) allele in the third intron of the bovine growth hormone gene in a large number of cattle breeds. Consideration of the breed frequencies in relation to their geographic origin shows a low frequency for breeds originating in Northern Europe...
