GENESYS: Genetics and Herd Management, Two Flexibility Levers in Dairy Cattle Farming
The GENESYS program explores genetics and herd management as key levers to enhance flexibility in dairy cattle production by evaluating herd x test day effects, analyzing genotype x environment interactions, and assessing crossbreeding strategies under varying feeding conditions.

Description détaillée
In response to market volatility and quota removal, the GENESYS program investigates the dual levers of genetics and herd management to increase dairy farm flexibility. It refines genetic evaluation by modeling herd x test day effects and classifies farm management profiles based on these effects. The program also examines genotype x environment interactions across dairy traits nationwide and conducts experimental studies on Holstein and Normande breeds under contrasting feeding regimes, revealing breed-specific adaptability and reproductive challenges. Finally, it assesses the rising use of dairy crossbreeding in France as a strategy to mitigate fertility issues.
