Udder, Claw, and Reproductive Health in Genomic Selection of the Czech Holstein

Popis výsledku v původním jazyce

The aim of this study was to construct an enhanced selection index using the genomic andeconomic parameters of new health disorders and current production and functional traits. Genomicevaluation for the incidence of clinical mastitis (CM), three claw disease traits, retained placenta(RET), metritis (MET), and cystic ovaries (CYS) was performed using linear animal models basedon producer-recorded data. Good correlations among the health disorders were found, and theirheritability estimates did not exceed 7%. Economic weights (EWs) for the health disorders wereEUR MINUS SIGN 132.10 for CM, EUR MINUS SIGN 128.87 for overall claw diseases, EUR MINUS SIGN 52.10 for RET, EUR MINUS SIGN 80.48for MET, and EUR MINUS SIGN 16.16 for CYS. These EWs indicate changes in the present value of the annualprofit per cow when increasing the incidence of the traits by one case per cow year. Selectionusing the enhanced index resulted in favourable responses for most of the new health disorders(e.g., MINUS SIGN 0.001 and MINUS SIGN 0.006 cases of RET and MET per cow year, respectively), and also in the currentbreeding objective traits (+49 kg of milk, MINUS SIGN 0.02% of calf losses). An index contribution of 7% for thenew health disorders was assessed as acceptable for the breeders.
