Genetic associations between somatic cell score and pathogen-specific subclinical mastitis in Norwegian Red cows.
The aim of this study was to estimate heritabilities of and genetic correlations between pathogen-specific subclinical mastitis (SCM) traits and lactation mean somatic cell score (LSCS) in Norwegian Red cattle. Based on data from 130 733 first-lactation cows four binary pathogen-specific SCM traits, Staphylococcus aureus, Streptococcus dysgalactiae, Streptococcus uberis and coagulase-negative s...
متن کاملAssociations between CXCR1 polymorphisms and pathogen-specific incidence rate of clinical mastitis, test-day somatic cell count, and test-day milk yield.
The CXCR1 gene plays an important role in the innate immunity of the bovine mammary gland. Associations between single nucleotide polymorphisms (SNP) CXCR1c.735C>G and c.980A>G and udder health have been identified before in small populations. A fluorescent multiprobe PCR assay was designed specifically and validated to genotype both SNP simultaneously in a reliable and cost-effective manner. I...
متن کاملRelationship of Somatic Cell Count and Mastitis: An Overview
Mastitis is characterized by physical, chemical and bacteriological changes in the milk and pathological changes in the glandular tissue of the udder and affects the quality and quantity of milk. The bacterial contamination of milk from the affected cows render it unfit for human consumption and provides a mechanism of spread of diseases like tuberculosis, sore-throat, Q-fever, brucellosis, lep...

متن کاملFeasibility of International Genetic Evaluations of Dairy Sires for Somatic Cell Count and Clinical Mastitis
Selection of foreign sires involves risk when genetic values for breeding goal traits are unknown. Information to support objective selection decisions concerning foreign sires are confined to the information from Interbull=s routine evaluations for production and conformation traits. Functional traits are associated with efficiency of production by their direct influence on costs of production...
