Estimation by simulation of the efficiency of the French marker-assisted selection program in dairy cattle (Open Access publication) (2008)

Guillaume, François, Fritz, Sébastien, Boichard, Didier, Druet, Tom

Abstract The efficiency of the French marker-assisted selection (MAS) was estimated by a simulation study. The data files of two different time periods were used: April 2004 and 2006. The simulation...

A first generation bovine BAC-based physical map (2004)

Schibler, Laurent, Roig, Anne, Mahé, Marie-Françoise, Save, Jean-Claude, Gautier, Mathieu, Taourit, Sead, ...

Abstract A first generation clone-based physical map for the bovine genome was constructed combining, fluorescent double digestion fingerprinting and sequence tagged site (STS) marker screening. The...

Combined analysis of data from two granddaughter designs: A simple strategy for QTL confirmation and increasing experimental power in dairy cattle (2003)

Bennewitz, Jörn, Reinsch, Norbert, Grohs, Cécile, Levéziel, Hubert, Malafosse, Alain, Thomsen, Hauke, ...

Abstract A joint analysis of five paternal half-sib Holstein families that were part of two different granddaughter designs (ADR- or Inra-design) was carried out for five milk production traits and...

Detection of genes influencing economic traits in three French dairy cattle breeds (2003)

Boichard, Didier, Grohs, Cécile, Bourgeois, Florence, Cerqueira, Frédérique, Faugeras, Rémi, Neau, André, ...

Abstract A project of QTL detection was carried out in the French Holstein, Normande, and Montbéliarde dairy cattle breeds. This granddaughter design included 1 548 artificial insemination bulls...

Use of maternal information for QTL detection in a (grand)daughter design (2002)

Bolard, Marc, Boichard, Didier

Abstract In a (grand)daughter design, maternal information is often neglected because the number of progeny per dam is limited. The number of dams per maternal grandsire (MGS), however, could be...

A new reciprocal translocation in a subfertile bull (2000)

Ducos, Alain, Dumont, Pascal, Séguéla, Anne, Pinton, Alain, Berland, Hélène, Brun-Baronnat, Corinne, ...

Abstract Three bulls of the Montbéliarde breed that exhibited fertility rates lower than 30% following more than 400 artificial inseminations were examined. Semen quality (sperm motility and...

Multiple Quantitative Trait Loci Mapping With Cofactors and Application of Alternative Variants of the False Discovery Rate in an Enlarged Granddaughter Design

Bennewitz, Jörn, Reinsch, Norbert, Guiard, Volker, Fritz, Sebastien, Thomsen, Hauke, Looft, Christian, ...

The experimental power of a granddaughter design to detect quantitative trait loci (QTL) in dairy cattle is often limited by the availability of progeny-tested sires, by the ignoring of already...

Fine Mapping and Physical Characterization of Two Linked Quantitative Trait Loci Affecting Milk Fat Yield in Dairy Cattle on BTA26

Gautier, Mathieu, Barcelona, Rosa Roy, Fritz, Sébastien, Grohs, Cécile, Druet, Tom, Boichard, Didier, ...

Previously, a highly significant QTL affecting fat yield and protein yield and mapped to the bovine BTA26 chromosome has been reported to segregate in the French Holstein cattle population. To...

Genetic and Haplotypic Structure in 14 European and African Cattle Breeds

Gautier, Mathieu, Faraut, Thomas, Moazami-Goudarzi, Katayoun, Navratil, Vincent, Foglio, Mario, Grohs, Cécile, ...

To evaluate and compare the extent of LD in cattle, 1536 SNPs, mostly localized on BTA03, were detected in silico from available sequence data using two different methods and genotyped on samples...

Fine Mapping of Quantitative Trait Loci Affecting Female Fertility in Dairy Cattle on BTA03 Using a Dense Single-Nucleotide Polymorphism Map

Druet, Tom, Fritz, Sébastien, Boussaha, Mekki, Ben-Jemaa, Slim, Guillaume, François, Derbala, David, ...

Fertility quantitative trait loci (QTL) are of high interest in dairy cattle since insemination failure has dramatically increased in some breeds such as Holstein. High-throughput SNP analysis and...
