Daughter pregnancy rate

WebThe objectives of this study were to assess the relationship between early genomic prediction of daughter pregnancy rate (GDPR) and pregnancy at the first service (P1), pregnancy at the end of lactation (PEND), number of services for conception (NSFC), days from calving to first service (TP1), and days open (TPEND). WebPTA's for Daughter pregnancy rates (DPR) measure genetic differences between bulls in fertility of their daughters. DPR predicts genetic improvement (or deterioration) in pregnancy rate for future daughters of a bull compared to a bull that is expected to produce no change (PTA DPR = 0).
