Genetic and Phenotypic Relationships between Clinical Mastitis, Laboratory Criteria, and Udder Height

Abstract

Genetic aspects of mastitis resistance were investigated where quantitative scores were determined for clinical mastitis, bacterial infection, and leucocyte count. Heritability and repeatability estimates were obtained for these scores, and phenotypic and genetic correlations between scores were estimated. Correlations also were obtained between udder height and the scores for clinical mastitis, bacterial infection, and leucocyte count.
