Correlation Between California Mastitis and Wisconsin Mastitis Test Reagents as Used in the Wisconsin Mastitis Test

Rheology of the gel formed in the California Mastitis Test.

The California Mastitis Test has previously been adapted for use in an inline, cow-side sensor and relies on the fact that the viscosity of the gel formed during the test is proportional to the somatic cell concentration. In this paper, the use of capillary and rotational viscometry was compared in light of the expected rheology of the gel formed during the test. It was found that the gel is no...

Detection of subclinical mastitis in dromedary camels (Camelus dromedaries) using somatic cell counts, california mastitis test and udder pathogen

A total of 120 quarter milk samples from 30 clinically healthy dromedary camel from Al-Jouf, Saudi Arabia were cultured to detect subclinical udder infection. The milk samples were screened by somatic cell count (SCC) and California mastitis test (CMT). Gram-positive cocci were the dominant recovered udder pathogen. The mean value of SCC was 125,000 cells/ mm. Infected quarter had generally hig...

Genetic Correlation between Test-Day Electrical Conductivity of Milk and Clinical Mastitis

Electrical conductivity (EC) of milk is an indicator of mastitis, and could, if it shows genetic variation and is genetically correlated to mastitis, be used in a breeding program where selection for reduced mastitis resistance is included. In this study, daily measurements of EC and mastitis were analyzed with a bivariate model. For EC, the estimated heritability was high (0.22 to 0.39), while...

Chemical and rheological aspects of gel formation in the California Mastitis Test.

The rheological properties of the CMT gel were analysed. Data are presented to demonstrate that the gel is a non-homogenous, visco-elastic, non-Newtonian fluid with rheopectic, and rheodestructive behaviour. The fundamental chemistry of the CMT is reviewed and a modified theory of gel formation is presented. The implications of the rheological properties and modified theory of gel formation for...
