Evaluation of somatic cell count thresholds to detect subclinical mastitis in Gyr cows.
The objectives of this study were (1) to determine the sensitivity (Se) and specificity (Sp) of somatic cell count (SCC) thresholds to identify subclinical mastitis in Gyr cows caused by major and minor pathogens; (2) to study the effects of month of sampling, rear or front mammary quarters, herd, intramammary infection (IMI), and bacterial species on SCC at quarter level; and (3) to describe t...
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 کاملThe association between the somatic cell count and isolated microorganisms during subclinical mastitis in heifers in Jordan
Mastitis is an important cause of early culling of dairy heifers. The aims of this study were to identify microorganisms that cause subclinical mastitis (SCM) in Holstein heifers in northern Jordan, to estimate the relative importance of various microorganisms, and to examine the correlation between the somatic cell count (SCC) and the isolated microorganisms. Composite milk samples were collec...
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...
