History and genetic diversity of African sheep: Contrasting phenotypic and genomic diversity. [PDF]

Anim Genet
Abstract Domesticated sheep have adapted to contrasting and extreme environments and continue to play important roles in local community‐based economies throughout Africa. Here we review the Neolithic migrations of thin‐tailed sheep and the later introductions of fat‐tailed sheep into eastern Africa.

Candidate signatures of positive selection for environmental adaptation in indigenous African cattle: A review

Animal Genetics, Volume 54, Issue 6, Page 689-708, December 2023., 2023
AbstractEnvironmental adaptation traits of indigenous African cattle are increasingly being investigated to respond to the need for sustainable livestock production in the context of unpredictable climatic changes. Several studies have highlighted genomic regions under positive selection probably associated with adaptation to environmental challenges ...

Genetic diversity of bovine populations raised in Senegal

Veterinary Medicine and Science, Volume 8, Issue 5, Page 2173-2182, September 2022., 2022
This study revealed that the animals in Senegal's cattle breeding programmes show low genetic diversity. This is mainly explained by reproductive isolation and selection pressure. Abstract Background The Gobra zebu and N'dama taurine cattle breeds are important genetic animal resources for Senegal.

Knowledge, Attitude, and Practice of Livestock Owners and Livestock Assistants towards African Trypanosomiasis Control in The Gambia

Journal of Parasitology Research, Volume 2022, Issue 1, 2022., 2022
Background. In Africa, it has been estimated that 50 million cattle and 70 million sheep and goats are at risk of animal African trypanosomiasis, and three million cattle die annually. Methods. This study was conducted in all the regions of The Gambia except Kombo Saint Mary Island (Banjul).

Population structure, inbreeding and admixture in local cattle populations managed by community‐based breeding programs in Burkina Faso

Journal of Animal Breeding and Genetics, Volume 138, Issue 3, Page 379-388, May 2021., 2021
Abstract High‐throughput genomic markers provide an opportunity to assess important indicators of genetic diversity for populations managed in livestock breeding programs. While well‐structured breeding programs are common in developed countries, in developing country situations, especially in West Africa, on‐farm performance and pedigree recordings ...

Cryptosporidium Infection and Associated Risk Factors among Cattle in the Central Region of Ghana

Journal of Parasitology Research, Volume 2021, Issue 1, 2021., 2021
Cryptosporidium species infects a wide number of animals including livestock all over the world. The current study was done to determine the prevalence and risk factors of Cryptosporidium infection among cattle in the Central Region of Ghana. Two hundred and eighty‐seven (287) faecal samples were randomly collected from animals on eight cattle farms in

The role of agro‐ecological factors and transboundary transhumance in shaping the genetic diversity in four indigenous cattle populations of Benin

Journal of Animal Breeding and Genetics, Volume 137, Issue 6, Page 622-640, November 2020., 2020
Abstract The indigenous cattle population of Benin is a diverse mix of taurine and hybrid breeds shaped by diverse ecological and climatic conditions with eight agro‐ecological zones (AEZ). Presumably, the taurine breeds face current endangerment due to ongoing indicine introgression following climate change and transboundary transhumance.
