Extract

Selection for milk production alone would lead to a genetic decline in cow fertility (e.g. Kadarmideen et al., 2000) thus incorporation of fertility in selection seems desirable. The Dairy Information System (DAISY) is a comprehensive recording scheme for insemination and health events and hence the data quality is more reliable for genetic analysis of cow fertility. The objective of this study was to analyse DAISY data to estimate sire breeding values and genetic parameters for various fertility measures based on insemination and calving events on daughters.
