Predicting Mastitis Resistance Breeding Values from Somatic Cell Count Indicator Traits
A new breeding value estimation procedure for mastitis traits has been implemented in the Dutch/Flemish dairy genetic evaluation. This breeding value estimation uses incidences of subclinical mastitis together with five indicator traits derived from test day somatic cell counts to predict the breeding value for resistance against subclinical and clinical mastitis (SCM and CM, resp.). The mastit...
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 کاملBreeding Cattle for Mastitis Resistance
The development of an immunological assay where cells isolated from blood are stimulated by an Staphylococcus aureus antigen in vitro is described. Variation was observed in the ability of cells isolated from young cattle, cows and bulls to respond in vitro to S. aureus, suggesting that differences in immune responsiveness may be measured by this method. Bull progeny groups were shown to have c...
متن کاملResponse to somatic cell count-based selection for mastitis resistance in a divergent selection experiment in sheep.
A divergent selection experiment in sheep was implemented to study the consequences of log-transformed somatic cell score (SCS)-based selection on resistance to natural intramammary infections. Using dams and progeny-tested rams selected for extreme breeding values for SCS, we created 2 groups of ewes with a strong divergence in SCS of approximately 3 genetic standard deviations. A survey of 84...
