Breeding options for nematode resistance in Lacaune dairy sheep

Animal, 2023
Due to progressing anthelmintic resistance of gastrointestinal nematodes (GIN), supportive measures are needed to control these parasites. In sheep, it has been shown that selection towards an increased nematode resistance is feasible and that faecal egg

Animal welfare of Lacaune lambs weaned from artificial feeding. [PDF]

Front Vet Sci
IntroductionNowadays, many dairy sheep farms opt for milk replacers after birth. Weaning lambs from milk replacers is expected to be a stressful situation.MethodsWith the aim of researching this practice on the animal behavior, body weight yields, and sanitary status of Lacaune lambs, 60 healthy animals from the same lambing house were employed.

Investigation of Prolific Sheep from UK and Ireland for Evidence on Origin of the Mutations in BMP15 (FecXG, FecXB) and GDF9 (FecGH) in Belclare and Cambridge Sheep [PDF]

, 2013
peer-reviewedThis paper concerns the likely origin of three mutations with large effects on ovulation rate identified in the Belclare and Cambridge sheep breeds; two in the BMP15 gene (FecXG and FecXB) and the third (FecGH) in GDF9.

THE CHANGES IN THE BLOOD’S ACID-BASE BALANCE OF THE LACAUNE SHEEP DURING DIFFERENT LACTATION STAGES

Poljoprivreda, 2022
The aim of the present study was to determine the acid-base balance in the blood of the Lacaune sheep during different lactation stages. Thirty lactating Lacaune sheep were involved in the research, and were monitored in the early (day 60), medium (day ...

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 (

Genetic parameters for milk somatic cell score and relationships with production traits in primiparous dairy sheep [PDF]

, 2007
A total of 13,066 first-lactation test-day records of 2,277 Valle del Belice ewes from 17 flocks were used to estimate genetic parameters for somatic cell scores (SCS) and milk production traits, using a repeatability test-day animal model.

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.
