Provisioning a Silk Road City: Herd Management Strategies at the Urban Site of Dzhankent, Kazakhstan

Archaeometry, EarlyView.
ABSTRACT This study presents evidence for herd management at the early medieval city of Dzhankent in southern Kazakhstan. Located along the Northern Silk Road, Dzhankent was a key trading node linking northern and southern areas between the 9th and 10th centuries ce.

‘Elbow grease and yellow soap’: Housework time in working‐class households in late‐nineteenth and early twentieth‐century Britain

The Economic History Review, EarlyView.
Abstract Housework is central to feminist calls for recognition of women's work, economic histories explaining the sexual division of labour, and claims regarding the progressive role of scientific knowledge. Yet little is known about the time it actually took. We address this lacuna.

Evaluating Selection Strategies Based on Inbreeding Load via Simulation

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Inbreeding load is the fraction of the mutation load that is due to recessive action of mutations. This load is only expressed in individual's inbred offspring. As such, inbreeding load contributes to genetic heterogeneity among individuals and can thus be used as a criterion of selection.

Description of the sheep ethogram and observations on dairy sheep farms

, 2023
L'étude des comportements exprimés par les ovins sauvages est un point de repère pour l'évaluation du comportement animal en élevage malgré les nombreuses adaptations du mouton domestique à leur milieu d'élevage. En effet, la liberté d'expression d'un comportement normal de son espèce est un des 5 principes du bien-être animal et connaitre les ...

Characterizing Runs of Homozygosity and Inbreeding in American Mink Using SNP Data and Pedigree Information

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Inbreeding increases the likelihood of deleterious recessive alleles becoming homozygous and consequently affecting economically important traits. Runs of homozygosity (ROH), the continuous homozygous segments of the genome and the higher than expected homozygosity (HOM) are genomic indicators of inbreeding, quantified as FROH and FHOM ...

Genetic Correlations Between Fleece Shedding and Production Traits Indicate Minimal Trade‐Offs When Breeding for Maternal Shedding Sheep

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Fleece shedding is becoming an increasingly important trait in sheep production systems focused on meat and dairy, where wool has limited economic value and reducing shearing costs is desirable. For inclusion in breeding programmes, a trait must exhibit genetic variation, sufficient heritability, and have well‐defined relationships with other ...

Estimates of Genetic Parameters for Ewe Longevity and Lifetime Reproductive Performance Traits in South African Merino Sheep

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Ewe's functional longevity impacts flock profitability by reducing annual ewe replacement costs and increasing ewe outputs over the production cycle. In this context, the main objective of this study was to estimate variance components and genetic parameters of five ewe longevity indicators in South African Merino sheep.

Genome‐Wide Association Studies for Anogenital Distance and Linear Type Traits in Gir Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Although linear type traits have been under selection in the Dairy Gir cattle for the past three decades, there are few studies exploring genetic architecture for these traits. The aim of this study was to identify candidate genes for anogenital distance and linear type traits in the Gir breed. For this study, the body measures of rump length (
