Characterisation of genetic diversity in indigenous cattle of East Africa: Use of microsatellite DNA techniques
نویسنده
چکیده
Indigenous cattle form the backbone of relevant and sustainable livestock production in most of eastern Africa because when compared with their exotic counterparts, they are better adapted to survive and reproduce under the region’s harsh environments. These cattle often possess valuable traits such as disease tolerance/resistance, high fertility, good maternal qualities, longevity, and adaptability to harsh conditions and poor-quality feeds—all of which are qualities that form the basis for low-input, sustainable agriculture. Indigenous cattle are vital to subsistence and economic development in eastern Africa, contributing 50% of the total food production from livestock (Jahnke 1982). They sustain the employment and income of millions of East Africans, two-thirds of whom are rural-based. They also provide transport, much of the draft used in cultivation of crops and large component of the manure essential to agriculture. In addition, they play an important role in African culture as they are used for gifts, dowry and cultural rituals. Some of their products are also medicinal.

Moroccan goats are characterized by the presence of different populations identified only based on their phenotypes. The objectives of this study were to assess the genetic differentiation of the Draa goat breed and to analyze its genetic structure and its relationships with other local populations using 12 microsatellite markers. The screening was done in South Eastern and Southern Morocco on ...

The aim of this study was to evaluate the Bali cattle genetic diversity and hybrid cattle using microsatellite markers. Blood samples (n=192) were collected from various cattle breed, i.e. Bali (n=96), Madura (n=48), and Peranakan Ongole (PO) Kebumen (n=48). The microsatellite locus used for assessing the genetic variation was INRA035, ILSTS006, ETH225, and HEL9, while the genetic profile was d...

African pastoralism: genetic imprints of origins and migrations.
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 in Africa. The earliest cattle originated within the African continent, but Near East and European ge...
