Signatures of positive selection in African Butana and Kenana dairy zebu cattle
Butana and Kenana are two types of zebu cattle found in Sudan. They are unique amongst
African indigenous zebu cattle because of their high milk production. Aiming to understand
their genome structure, we genotyped 25 ...
Whole-Genome Resequencing of Red Junglefowl and Indigenous Village Chicken Reveal New Insights on the Genome Dynamics of the Species
The red junglefowl Gallus gallus is the main progenitor of domestic chicken, the
commonest livestock species, outnumbering humans by an approximate ratio of six
to one. The genetic control for production traits have been ...
Mitochondrial DNA variation reveals maternal origins and demographic dynamics of Ethiopian indigenous goats
The Horn of Africa forms one of the two main historical entry points of domestics
into the continent and Ethiopia is particularly important in this regard. Through the
analysis of mitochondrial DNA (mtDNA) d-loop
region ...
Indigenous knowledge, practices and preferences in control of gastrointestinal nematodes in Bonga and Horro sheep of Ethiopia
Gastrointestinal nematodes (GIN) remain one of the main health and production constraints of sheep globally. Considering alternatives to anthelmintics in control of GIN of sheep has become important mainly due to development ...
Increased number of large non-atretic follicles and codominance effects account for high litter sizes in Bonga sheep
To understand the ovarian basis for prolificacy of Bonga sheep, a total of 31 ewes were selected based on litter size (LS) records and divided into two groups: High Prolificacy (HP) (n = 20) with LS ≥ 2 and Low Prolificacy ...
The maternal origin of indigenous domestic chicken from the Middle East, the north and the horn of Africa
Indigenous domestic chicken represents a major source of protein for agricultural communities around the world. In the Middle East and Africa, they are adapted to hot dry and semi-dry areas, in contrast to their wild ...
Genome‑wide scans identify known and novel regions associated with prolifcacy and reproduction traits in a sub‑Saharan African indigenous sheep (Ovis aries)
Maximizing the number of ofspring born per female is a key functionality trait in commercial- and/or subsistence-oriented
livestock enterprises. Although the number of ofspring born is closely associated with female fertility ...
Novel and known signals of selection for fat deposition in domestic sheep breeds from Africa and Eurasia
Genomic regions subjected to selection frequently show signatures such as within-population reduced nucleotide diversity and outlier values of differentiation among differentially selected populations. In this study, we ...
Community-based sheep breeding programs generated substantial genetic gains and socioeconomic benefits
Community-based breeding programs (CBBPs) for small ruminants have been suggested as alternatives to centralised, government-controlled breeding schemes which have been implemented in many developing countries. An innovative ...
Estimates of genetic parameters and trends for reproduction traits in Bonga sheep, Ethiopia
Investigation was carried out to assess the effects of environmental factors and to estimate genetic parameters and trends for
reproductive traits in Bonga sheep, Ethiopia. Animals used in this study were managed by two ...
