Genetic analysis of clinical mastitis data for Holstein cattle in the Czech Republic

Popis výsledku v původním jazyce

Abstract Cases of mastitis were recorded from 22 812 lactations of 10 294 cows on seven farms in the Czech from 2000 to 2012. The per cow number of clinical mastitis (CM) cases per lactation (CM1), number days of CM per lactation (CM2), and CM consideredas an all-or-none trait (CM3) with values of 0 (no CM or 1 (at least 1 CM case) were analyzed with linear animal models. Bivariate linear animal models were for estimation of genetic correlations between CM traits and average lactation somatic cell score (SCS305), 305-day milk (MY305), fat (FY305) and protein (PY305) yield, and interval between calving and first (INT) and days open (DO). Factors included in the model of choice were parity, herd effect, year calving, calving season, permanent environmental effect of the cow, and additive genetic effect of the cow. heritabilities for CM traits were in the range of 0.09 to 0.10. Genetic correlations of SCS305 with traits 1, 2, and 3 were 0.22 ? 0.062, 0.23 ? 0.064, and 0.29 ? 0.086, respe
