Mitochondrial DNA analysis of ancient sheep from Kazakhstan: evidence for early sheep introduction

Heliyon, 2021
Kazakhstan covers a vast territory, and it has always been a land of nomadic pastoralism, where domesticated horses and sheep were moved by nomadic people across the steppe.

Health status and microbial (Pasteurellaceae) flora of free‐ranging bighorn sheep following contact with domestic ruminants

Wildlife Society Bulletin, 2014
Eighteen bighorn sheep (Ovis canadensis) with known or suspected contact with domestic ruminants on public or private land were removed to prevent possible disease transmission.

Identification of Ancestry Informative Marker (AIM) Panels to Assess Hybridisation between Feral and Domestic Sheep

Animals, 2020
Hybridisation of wild populations with their domestic counterparts can lead to the loss of wildtype genetic integrity, outbreeding depression, and loss of adaptive features.

Volatility in Live Calf, Live Sheep, and Feed Wheat Return Markets: A Threat to Food Price Stability in Turkey

Agriculture, 2022
The volatility of meat prices affects the accessibility and even food security of some consumers in Turkey. This study analyses the prices of selected livestock and a major feed component, wheat, as well as the exchange rate of the domestic currency in ...

EPIDEMIC PASTEURELLOSIS IN A BIGHORN SHEEP POPULATION COINCIDING WITH THE APPEARANCE OF A DOMESTIC SHEEP [PDF]

Journal of Wildlife Diseases, 2008
A pneumonia epidemic reduced bighorn sheep (Ovis canadensis) survival and recruitment during 1997-2000 in a population comprised of three interconnected wintering herds (Kenosha Mountains, Sugarloaf Mountain, Twin Eagles) that inhabited the Kenosha and Tarryall Mountain ranges in central Colorado, USA.

Identification of selective sweep and associated QTL traits in Iranian Ovis aries and Ovis orientalis populations

Frontiers in Genetics
IntroductionIdentifying genomic regions under selection is the most challenging issue for improving important traits in animals. Few studies have focused on identifying genomic regions under selection in sheep.

A case of thanatosis in domestic sheep

Behaviour
Abstract Thanatosis (feigning death, defensive tonic immobility) is a widespread anti-predator behavioural strategy in animals. Animals that have evolved this behaviour react to physical contact with the predator by displaying a persistent tonic immobility that makes them look like dead prey. This phenomenon has often been observed in

Genomic evidence of improved fertility and adaptation in Iranian domestic sheep attributed to introgression from Asiatic Mouflon and urial

Scientific Reports
Due to the diverse climate in Iran, there has been an opportunity for the emergence of different domestic sheep breeds. On the other hand, two of the seven wild sheep species have settled in the broad areas of Iran.

Chromosome synapsis, recombination and epigenetic modification in rams heterozygous for metacentric chromosome 3 of the domestic sheep Ovis aries and acrocentric homologs of the argali Ovis ammon

Вавиловский журнал генетики и селекции, 2019
Hybridization of domestic animal breeds with their wild relatives is a promising method for increasing the genetic diversity of farm animals. Resource populations derived from the hybridization of various breeds of domestic sheep with mouflon and argali ...
