Název v původním jazyce

Relationships between health disorders and production and reproduction traits of Holstein cows in the Czech Republic

Popis výsledku v původním jazyce

The objective of this study was to evaluate the relationships among several health disorders: milk fever (MF; hypocalcemia and parturient paresis), retained placenta (RP; retained fetal membranes), metritis (ME; endometritis and pyometra), ovarian cysts(OC; follicular and luteal cysts), clinical mastitis (CM), and lameness (LS; foot and leg problems) on the productive and reproductive performance of dairy cows. The dataset of 1432 Holstein cows calved between January 2000 and April 2004 from 4 commercial dairy herds was analyzed by the linear regression model which included the effects of herd-year-season of calving, parity, Breeding value level for milk yield or FCM yield level, respectively, incidences of studied fertility and health disorders, andregression to the first calving age within parity. MF had a significant influence (P < 0.01 and P <0.05) on milk yield in 100 days of lactation (100d-Mkg) and on FCM yield in 305 days (305d-FCM), ME occurrence affected (P < 0.001) milk yi
