DeLaval mastitis test CMT(California mastitis test) - for detection of subclinical mastitis
The Somatic Cell Count,SCC(number of somatic cells), is for a healthy cow normally below 150 000-200 000 cells/ml milk.
An increased number of SCC is in most cases the result of an udder infection.
The DeLaval CMT is a useful tool that indicates the level of SCC, and therefor the udder healthy of the individual cow. The DeLaval CMT is easy and quick to use, performed and evaluated on the farm.
What to use the CMT:
- Identifying infected udders and quarters on a reqular basis
- Follow up udder treatment
- Monitoring the development of the SCC after calving
- Checking the udder healthy before purchase and sale of lactating cows
How to perform the CMT(see illustrations)
1, Milk and discard a few milk-jets from each quarter. Sample a few milk-jets from each quarter into each plate cup.prevent foam building.
2, Remove excess of milk from the cups by tilting the plate until the bottom mark turns visible. Don't mix the milk samples!
3, Add 3 ml of test liquid to each cup by pressing the pump once.
4, Mix the content by rotating the plate carefully, and read off the test.
How to interpret the CMT(see illustrations):
Changes appearing in the consistency of the milk/reagent mixture allow conclusions to be drawn about the SCC of the milk:
- Negative: up to 200 000 cells/ml milk.
Mixture remain a homogenous liquid, with no evidence of thickening. Indication of a healthy udder.
+ Slightly positive: 150 000 - 500 000 cells/ml milk.
Appearance of streaks can be made visible during rotation of the plate.
++ Positive: 400 000 - 1.5 million cells/ml milk.
Distinct thickening during rotation, but no gel. The mixture is slow in following the plate movements.
+++ Very positive: 800 000 - 5 millions cells/ml milk.
Slight formation of gel. Gel follows the rotation plate very slowly.
++++ Extermely positive: >5 million cells/ml milk.
Solid gel formed that adheres to the base of the plate. Gel follows movements very slowly and the gel collects in the centre.
When an increased SCC is noticed in one or several quarters, new milk samples should be taken and sent for analyses to confirm the cause. Bases upon the result a relevant treatment should be performed advised by your veterinarian.
Warning and precautions:
Keep out of reach of children. Store riginal container, with lid tightly closed.
Do not store in direct sunlight, and avoid freezing.
