Genomic selection in the French Lacaune dairy sheep breed [PDF]

Journal of Dairy Science, 2012
Genomic selection aims to increase accuracy and to decrease generation intervals, thus increasing genetic gains in animal breeding. Using real data of the French Lacaune dairy sheep breed, the purpose of this study was to compare the observed accuracies of genomic estimated breeding values using different models (infinitesimal only, markers only, and ...

Genetic analysis of milking ability in Lacaune dairy ewes [PDF]

Genetics Selection Evolution, 2006
Abstract The milking ability of Lacaune ewes was characterised by derived traits of milk flow patterns, in an INRA experimental farm, from a divergent selection experiment in order to estimate the correlated effects of selection for protein and fat yields.

Risks for animal health related to the presence of ochratoxin A (OTA) in feed

EFSA Journal, Volume 21, Issue 11, November 2023., 2023
Abstract In 2004, the EFSA Panel on Contaminants in the Food Chain (CONTAM) adopted a Scientific Opinion on the risks to animal health and transfer from feed to food of animal origin related to the presence of ochratoxin A (OTA) in feed. The European Commission requested EFSA to assess newly available scientific information and to update the 2004 ...

Factors affecting milk yield and ewe's lactation curves estimated with test-day models

Czech Journal of Animal Science, 2006
Test-day records of purebred Tsigai, Improved Valachian and Lacaune ewes were analysed with a general linear model in order to investigate the effects of flock-test day, lactation number, days in milk, litter size and month of lambing. In total, 121 576 (

Associations between small ruminant lentivirus infection and total milk yield and somatic cell count in a dairy sheep flock

Veterinary Record, Volume 192, Issue 11, 3/10 June 2023., 2023
Abstract Background Small ruminant lentiviruses (SRLVs) are lentiviruses of sheep and goats, formerly known as maedi–visna (MV) in sheep and caprine encephalitis and arthritis in goats. In sheep, SRLVs commonly cause progressive pneumonia, wasting and indurative mastitis.

Response to somatic cell count-based selection for mastitis resistance in a divergent selection experiment in sheep [PDF]

, 2009
A divergent selection experiment in sheep was implemented to study the consequences of log-transformed somatic cell score (SCS)-based selection on resistance to natural intramammary infections.

STK36 splice site variant in an Australian Shepherd dog with primary ciliary dyskinesia

Animal Genetics, Volume 54, Issue 3, Page 412-415, June 2023., 2023
Abstract Primary ciliary dyskinesia (PCD) represents a group of diseases characterized by impaired movement of cilia and subsequent health problems in diverse organ systems, notably the respiratory tract. Almost 50 candidate genes for PCD are known in humans.

Profitability of a dairy sheep genetic improvement program using artificial insemination [PDF]

, 2010
This simulation study investigated the farm-level economic benefits of a genetic improvement scheme using artificial insemination (AI) with fresh ram semen in dairy sheep of the Chios breed in Greece. Data were collected from 67 farms associated with the

Genotyping of DNA pools identifies untapped landraces and genomic regions to develop next‐generation varieties

Plant Biotechnology Journal, Volume 21, Issue 6, Page 1123-1139, June 2023., 2023
Summary Landraces, that is, traditional varieties, have a large diversity that is underexploited in modern breeding. A novel DNA pooling strategy was implemented to identify promising landraces and genomic regions to enlarge the genetic diversity of modern varieties.
