Assessment of accuracy of genomic prediction for French Lacaune dairy sheep [PDF]
Journal of Dairy Science, 2014 Genomic selection in Lacaune dairy sheep was investigated based on genotypes from the OvineSNP50 BeadChip (Illumina Inc., San Diego, CA). Historical artificial insemination progeny-tested rams formed a population of 2,892 genotyped rams. Additional ungenotyped rams and females were included by single-step genomic BLUP (ssGBLUP).

Effect of subdivision of the Lacaune dairy sheep breed on the accuracy of genomic prediction
Journal of Dairy Science, 2023 : Genomic selection was deployed in Lacaune dairy breed in 2015. Lacaune population split in 1972 into 2 breeding companies with associated flocks, and there have been very few exchanges of animals between the subpopulations, leading to divergence of the

Segregation of a major gene influencing ovulation in progeny of
Genetics Selection Evolution, 2002 Inheritance of the ovulation rate (OR) in the Lacaune meat breed was studied through records from a small nucleus of 36 hyper-prolific ewes screened on farms on the basis of their natural litter size, and from progeny data of three selected Lacaune sires.

Some productive and reproductive traits in sheep from the Bulgarian dairy synthetic population (BDSP) and its crosses with Lacaune and Assaf: 2. Phenotypic parameters [PDF]
Biotechnology in Animal Husbandry, 2021 Bulgarian Dairy Synthetic Population (BDSP) and its crosses with other dairy breeds are the most numerous sheep population in Bulgaria. There are significant phenotypic diversities and different levels of productivity. The aim of the study is to research

Genetic parameters of some productive and reproductive traits in sheep from the Bulgarian dairy synthetic population (BDSP) and its crosses with Lacaune and Assaf [PDF]
Biotechnology in Animal Husbandry, 2021 Dominating in recent years in Bulgaria are the sheep from the Bulgarian Dairy Synthetic Population (BDSP) and its crosses with other dairy breeds. This in turn leads to significant, scientifically based genetic and phenotypic diversity and different ...

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 ...
