Fauna launch in Bangalore, Karnataka

Updated: Oct 26, 2021



Intended Use

The Fauna SCC test is intended to be used for the quantitative measurement of the somatic cell count in cow milk samples. This system is intended to be used to ensure the high quality of milk being distributed in the market and to enable early on-farm mastitis detection.


Test Principle

The Fauna SCC test is based on the reaction between a dye embedded on the membrane of the test strip and an enzyme found on the cells in the milk. This reaction makes the reaction window of the test strip change from white to a blue color which is interpreted and estimated by the Fauna device using the principle of reflectance photometry. The higher the intensity of the blue color, the higher the SCC value of the milk sample.


Measuring Range: 100 to 1200 cells/µL


Test Time: 5 minutes


Operating Temperature: 7˚C to 35˚C


Sample volume: about 80 to 90 µL


Performance Summary

The Fauna SCC test was validated at many sites in India. The accuracy and precision achieved by the testing system are comparable to standard analyzers such as DeLaval Cell Counter.


Precision evaluation

The precision of the Fauna SCC Test at three different levels of somatic cell counts in cow milk samples was estimated as follows :

SCC category (cells/µL)

%CV

<200

12.6

200 to 1000

3.7

>1000

7.3

Accuracy evaluation during pilot at Bengaluru


1. Khedda Resorts, Kanakapura Main Road

Reference Analyzer: DeLaval Cell Counter

Number of samples: 40

Breeds: Holstein Fresians, Sahiwal and Jersey


The Fauna SCC test showed good correlation versus the DeLaval Cell Counter with R2=0.82 and 100% and 93% of the samples agreeing with the DeLaval Cell Counter measurements in the healthy and mastitis-infected categories, respectively. Overall, the Fauna SCC test has a sensitivity of 93% and specificity of 100% versus the DeLaval Cell Counter.


2. Sri Sri Gaushala, Kanakapura Main Road

Reference Analyzer: DeLaval Cell Counter

Number of samples: 76

Breeds: Indigenous breeds such as Kankrej, Gir, Thaparkar, Ongole

The Fauna SCC test showed good correlation versus the DeLaval Cell Counter with R2=0.82 and 100% and 67% of the samples agreeing with the DeLaval Cell Counter measurements in the healthy and mastitis-infected categories, respectively. Overall, the Fauna SCC test has a sensitivity of 78% and specificity of 100% versus the DeLaval Cell Counter.

I have a large requirement for detection of antibiotics (oxytetracyclines and betalactams) and aflatoxins. How can I get more details?
