A Model for the Genetic Evaluation of Number of Clinical Mastitis Cases per Lactation in Czech Holstein Cows

Popis výsledku v původním jazyce

Cases of mastitis from 9,550 lactations of 6,242 cows were recorded on 5 farms in the Czech Republic from 1996 to 2008. The number of clinical mastitis (CM) cases per cow adjusted to a lactation length of 305 d was analyzed with 4 linear single-trait animal models and one 3-trait model, which also included lactation mean somatic cell score and 305-d milk yield. From both the single-trait and multiple-trait models, the estimated heritability of number of CM cases was 0.11 plus minus 0.015. The heritability estimates for lactation mean somatic cell score and 305-d milk yield were 0.17 plus minus 0.019 and 0.25 plus minus 0.011, respectively, and the genetic correlations of these traits with number of CM cases were 0.80 plus minus 0.059 and 0.34 plus minus 0.079, respectively. Genetic evaluation of the number of CM cases in Czech Holstein could be carried out including data from all parities and using a 3-trait animal model with somatic cell score and milk yield as additional traits.
