Development of a Single Step Genomic Evaluation of health traits and relationships with dairy traits in French Holsteins
Overview & Synopsis
Selecting for better health has become of primary importance for the dairy industry. In France, where no national database exists for health traits (except mastitis), a collaborative project has been implemented to explore and evaluate farmer health records. Around 10% of herds record health events accurately. Genetic parameters of 4 disorders have been studied here: Displaced Abomasum (DA), Milk Fever (MF), Metritis (MET) and Retained Placenta (RP). Heritabili-ties are low (1-2%), but health traits have moderate genetic correlations with some dairy traits (0.15-0.45). Based on EBV obtained with ssGBLUP for the four health traits, the daughters’ incidence of best EBV bulls versus worst bulls is reduced by a factor of 2 minimum.
