Validity of somatic cell count as indicator of pathogen-specific intramammary infections.
The objective of this study was to determine whether somatic cell count (SCC) was an effective test, with a sensitivity exceeding 85%, to determine species-specific bacterial infections. In addition, the relation between the SCC and various udder pathogen groups was investigated. SCC thresholds of greater than 200 000 cells/mL were used in quarter and greater than 150 000 cells/mL in composite ...
متن کاملDirect and indirect measurement of somatic cell count as indicator of intramammary infection in dairy goats
BACKGROUND Mastitis is the most important and costly disease in dairy goat production. Subclinical mastitis is common in goats and is mainly caused by contagious bacteria. Several methods to diagnose subclinical mastitis are available. In this study indirect measurement of somatic cell count (SCC) by California Mastitis Test (CMT) and direct measurement of SCC using a portable deLaval cell coun...
متن کاملIntramammary Infections and Somatic Cell Counts across the Dry Period
Take Home Message Use of intramammary antimicrobial dry cow treatment (DCT) is fundamental for effective mastitis control but even with the use of DCT, about 2530% of cows may have quarters that maintain chronic intramammary infections across the dry period Quarters with chronic intramammary infections have 4 times increased risk of having clinical mastitis in the current lactation as compa...
متن کاملSomatic Cell Count as an Indicator of Udder Health Status under Modern Dairy Production: a Review
Mastitis, an important disease of dairy animals, influences the quality and quantity of milk. Penetration of pathogenic microorganisms in the teat canal irritates and invades the delicate mammary tissue, causing an inflammatory response and consequent changes occur in the milk. Degree of these changes depends on the infecting agent and the inflammatory response. Mastitis, the inflammation of th...
متن کاملDynamics of somatic cell counts and intramammary infections across the dry period.
The objectives of this research were to study the relationship between somatic cell count (SCC) and intramammary infection (IMI) across the dry period and the risk of subclinical mastitis at the first dairy herd improvement (DHI) test of the subsequent lactation. A secondary objective was to determine SCC test characteristics for diagnosis of IMI at both the cow and quarter levels. A total of 2...
