Phenotypic characterization of Tunisian sheep breeds for resistance to abomasal parasites
The aim of this work is to study the genetic resistance of the Barbarine sheep to GIN infestation. This is a preliminary paper about the phenotypic measurements that were collected and compiled in a single phenotype database. ...
Evaluation of Awassi sheep genotypes for growth, milk production and milk composition
We evaluated growth, milk production and composition of Awassi genotypes based on 9 years data collected from the International Center for Agricultural Research in the Dry Areas (ICARDA) flock kept in Tal Hadya station, ...
Community-Based Breeding Program is an attractive option for genetic improvement of small ruminants
In small ruminants, centralized breeding schemes, entirely managed and controlled by governments – with minimal, if any, participation by farmers – were developed and implemented in many developing countries. Such programs ...
Genome variation in tick infestation and cryptic divergence in Tunisian indigenous sheep
Background: Ticks are obligate haematophagous ectoparasites considered second to mosquitos as vectors and reservoirs of multiple pathogens of global concern. Individual variation in tick infestation has been reported in ...
Genomic footprints of dryland stress adaptation in Egyptian fattail sheep and their divergence from East African and western Asia cohorts
African indigenous sheep are classified as fat-tail, thin-tail and fat-rump hair sheep. The fat-tail are well adapted to dryland environments, but little is known on their genome profiles. We analyzed patterns of genomic ...
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 ...
Genome-Wide Scans Reveal Multiple Selection Sweep Regions in Indigenous Sheep (Ovis aries) from a Hot Arid Tropical Environment
Animals living in extreme environments demonstrate the adaptive resiliency of species to diverse ecosystems. This research suggests that the possible selection pressures shaping the genome architecture of the study populations ...
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 ...
Intra-population SNP analysis identifies signatures for grazing stress tolerance in Egyptian local goats
The need to support agricultural industries and human livelihoods in dryland environments using adapted livestock is becoming an unavoidable priority as prospects of global warming become even more evident. Here, using the ...
Genome-wide Analysis of Small Ruminant Tolerance to Grazing Stress Under Arid Desert
There are three major hot and dry deserts in North America, all located in the Western United States and Northern Mexico. Desert areas are facing serious environmental challenges, most importantly drought and water shortages ...
