California Mastitis Test
The California Mastitis Test (pronunciation: /ˌkælɪˈfɔːrnjə mæˈstaɪtɪs tɛst/) is a simple and rapid test used to detect subclinical mastitis in dairy cows. The test was developed in California, hence the name.
Etymology
The term "mastitis" originates from the Greek word "mastos" meaning "breast" and the suffix "-itis" indicating inflammation. The term "California" is derived from the U.S. state where the test was first developed.
Procedure
The California Mastitis Test involves the collection of a milk sample from each quarter of the udder. The sample is then mixed with a reagent that causes a reaction with the somatic cells in the milk. The degree of gel formation or precipitation is then observed and scored. The higher the score, the greater the likelihood of mastitis.
Interpretation
The results of the California Mastitis Test are interpreted based on the degree of gel formation or precipitation. A score of '0' indicates no gel formation and is considered negative. A score of '1' indicates slight gel formation and is considered suspicious. A score of '2' indicates distinct gel formation and is considered weakly positive. A score of '3' indicates strong gel formation and is considered strongly positive.
