The physiological and behavioural responses of sheep exposed to heat load within intensive sheep industries [PDF]

, 2006
The live export and feedlotting industries are the major intensive sheep industries in Australia. During live shipment, sheep are exposed to prolonged periods of high heat and humidity, with little relief for several days, while environmental conditions ...

Cardiac morphological and morphometric analysis of Ardea alba

The Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Convergent genomic signatures of domestication in sheep and goats [PDF]

Nature Communications, 2018
AbstractThe evolutionary basis of domestication has been a longstanding question and its genetic architecture is becoming more tractable as more domestic species become genome-enabled. Before becoming established worldwide, sheep and goats were domesticated in the fertile crescent 10,500 years before present (YBP) where their wild relatives remain ...

Impact of sea transport on animal welfare: Assessing the welfare and feeding behaviour of horned and polled sheep and cattle during export [PDF]

, 2008
The social and feeding behaviours of sheep and cattle segregated according to whether they had horns were investigated during live shipment, to determine the effects of mixing animals with and without horns within specification.

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals

The Anatomical Record, EarlyView.
Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...

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.

Globally dispersed Y chromosomal haplotypes in wild and domestic sheep

, 2006
To date, investigations of genetic diversity and the origins of domestication in sheep have utilised autosomal microsatellites and variation in the mitochondrial genome.

Proteinase K-Resistant Material in ARR/VRQ Sheep Brain Affected with Classical Scrapie Is Composed Mainly of VRQ Prion Protein [PDF]

, 2011
Classical scrapie is a prion disease in sheep and goats. In sheep, susceptibility to disease is genetically influenced by single amino acid substitutions.

Body mass and sex estimation from lower carnassial tooth morphometry in the endangered Iberian wolf (Canis lupus signatus): An ecomorphological analysis of sexual size dimorphism

The Anatomical Record, EarlyView.
Abstract The Iberian wolf (Canis lupus signatus) is an endangered subspecies characterized by highly fragmented populations and increasing human–carnivore conflict across the Iberian Peninsula. Although body mass strongly influences predator–prey dynamics and ecological performance, quantitative assessments of sexual size dimorphism (SSD) and body mass

The Seroprevalence of Chlamydia abortus in Montana Domestic Rangeland Sheep Varies by Breed, Flock and Herding Practices

Veterinary Medicine and Science
Background Ovine enzootic abortion (OEA) is a reproductive disease in domestic sheep characterized by late‐term abortions occurring 2–3 weeks before term and leading to economic losses for sheep producers.
