Abstract Background In France, implementation of genomic evaluations in dairy cattle breeds started 2009 and this has modified the breeding schemes drastically. context, goal our study was to understand impact selection on genetic diversity bulls from three French born between 2005 2015 (Montbéliarde, Normande Holstein) factors that are involved. Methods We compared annual gains, inbreeding rates based runs homozygosity (ROH) pedigree data, mean ROH length within breeds, before after...
Milk quality in dairy cattle is routinely assessed via analysis of mid-infrared (MIR) spectra; this approach can also be used to predict the milk's cheese-making properties (CMP) and composition. When method high-throughput phenotyping combined with efficient imputations whole-genome sequence data from cows' genotyping data, it provides a unique powerful framework which carry out genomic analyses. The goal study was use identify genes gene networks associated milk CMP composition...
The genetic determinism of the calving and suckling performance beef cows is little known whereas these maternal traits are major economic importance in cattle production systems. This paper aims to identify QTL regions candidate genes that affect Blonde d'Aquitaine breed. Three were studied: effect on score from field data, pelvic opening recorded station for primiparous cows. other related also analysed: weaning weight milk yield udder swelling A total 2,505 animals genotyped various chip...
In beef cattle, maternal care is critical for calf survival and growth. Our objective was to evaluate the major sources of additive genetic variation in behavior suckling performance two genetically close breeds. Maternal assessed based on (MB), milk yield (MY) udder swelling score (US) 1236 Blonde d'Aquitaine cows 1048 Limousin cows. MB scored just after calving describe intensity dam's protective towards her calf. Most were genotyped using low-density chip EuroG10K BeadChip, imputed...
Compared to national evaluations, international collaboration projects further improve accuracies of estimated breeding values (EBV) by building larger reference populations or performing a joint evaluation using data (or proxy them) from different countries. Genomic selection is increasingly adopted in beef cattle, but, date, the benefits including genomic information evaluations have not been explored. Our objective was develop an cattle single-step and investigate its impact on accuracy...
Les aptitudes du lait à la transformation en fromage sont étroitement liées sa composition. Ces caractères, difficiles mesurer directement, ont été prédits partir des spectres dans le moyen infrarouge (MIR) race Montbéliarde (projet From’MIR). Cet article rassemble les résultats de l’analyse déterminisme génétique fromagères et composition fine lait, prédites six millions MIR 400 000 vaches. caractères modérément fortement héritables corrélations génétiques entre fromagers (rendements...
A key genetic component of the female fertility, calving-to-first-heat interval (CFHI), was evaluated on Limousin cattle. In a large-scale experimental design, 3,923 cows spread over 35 farms were phenotyped during 4 years. Accelerometer collars used to detect first heat after calving. After determining non-genetic effects CFHI, evaluation potential animals then carried out using two-step genomic selection model. Heritability CFHI at 6% and predictive ability, cross validation direct values,...
