TLDR
Daily prevalence rate of CM was shown to be the best among various indicators of CM susceptibility, because it accounted for the censored character of the data and for repeated cases of CM within lactations, and it should be included as a goal in the breeding program.About:

Invited review: Incidence, risk factors, and effects of clinical mastitis recurrence in dairy cows.
Hossein Jamali,Herman W. Barkema,Mario Jacques,Eve-Marie Lavallée-Bourget,François Malouin,Vineet Saini,Henrik Stryhn,Simon Dufour +7 more
TL;DR: The most important effects of recurrent CM were the milk yield reduction following a recurrent CM case, which was reported to be similar to that of the firstCM case, and the increased risk of culling and mortality, which were reported to surpass those of first CM cases.

Selection for Profit in Cattle: I. Economic Weights for Purebred Dairy Cattle in the Czech Republic
TL;DR: In this article, a bioeconomic model for dairy cattle production was used to estimate economic values of 18 traits for dairy sires in purebred Holstein and Czech Fleckvieh populations.

Economic impact of mastitis in dairy cows
TL;DR: The economic loss associated with clinical (CM) and subclinical (SCM) mastitis under current Swedish farming conditions was assessed using mixed linear models and the most extensive yield loss was estimated when CM developed in early lactation and when SCM occurred in late lactation.

The incidence and aetiology of clinical bovine mastitis on 14 farms in Northland, New Zealand
TL;DR: A higher incidence of staphylococcal clinical mastitis on dairy farms from Northland than has been reported in other regions of New Zealand is demonstrated.
Journal ArticleDOI
Variation in herd level mastitis indicators between primi- and multiparae in Dutch dairy herds.
TL;DR: Composite somatic cell count data from the national test day recording and reported cases of farmer diagnosed clinical mastitis were used to estimate the occurrence of mastitis from July 2004 to June 2005 in primi- and multiparae in the Netherlands.

Production effects related to mastitis and mastitis economics in dairy cattle herds.
TL;DR: To support decision making for udder health control, it is necessary to use a marginal approach, based on the comparison of the losses avoided and the additional costs of modified plans, compared to the existing ones.
Journal ArticleDOI
Adjustment of test-day milk, fat and protein yield for age, season and stage of lactation
TL;DR: The adjustment of test-day yields for age at calving and stage of lactation was improved by using mathematical functions.

The costs of production diseases in dairy herds in England
M. A. Kossaibati,R. J. Esslemont +1 more
TL;DR: Economic losses due to common health problems in dairy cattle were investigated in 90 Friesian/Holstein herds, which calved in England during the 1992/1993 season with an average annual yield of about 6000 l per cow.

TL;DR: Mastitis is the most costly disease of dairy cows and will maintain this role in the foreseeable future.

Estimation of Genetic and Phenotypic Parameters for Clinical Mastitis, Somatic Cell Production Deviance, and Protein Yield in Dairy Cattle Using Gibbs Sampling
TL;DR: The results of this paper make clear the importance of including clinical mastitis in the breeding goal and the usefulness of somatic cell production deviance as the indicator trait forclinical mastitis.
