Milk Test Kits
Milk Test kits are simple-to-use low-cost tools that increase the health of cows as well as to prevent costly diseases in the dairy herd. These tests can detect the presence of antibiotic residues in the milk. These tests are a great alternative to bacterial tests using regular plate counts and the coliform culture. They are suggested for farmers to utilize regularly since they can detect patterns that may signal specific problems with the farm. The farmer can also see the effect of changes in the equipment or processes on bacterial counts by using regularly scheduled testing. Regular water tests are advised.


Milk Test Kits come in many types, each with their own benefits and drawbacks. Coliform Count Plate of test you want to be performed and the process of milk production will determine the test kit you select. Some of the factors to consider when selecting a test kit are listed below:



Certain Milk Test kits require a sample control, while others do not. The control sample can be used to confirm the test results. Choose the correct control sample, since a sample that has a low level contamination can result in an error being created in the test results. It is important to use controls when carrying out the test. Testing without an appropriate control could be difficult to interpret and should only be performed only by experienced users.


The past was when testing for bacterial contamination of raw milk was carried out by culturing techniques that required several hours in an incubator. It is impractical to use this time-consuming method on a farm. Rapid bacteriologic tests on farms for example, like the RAWMI Common Standards standard plate count (SPC) and coliform tests, has reduced the amount of testing required and allowed for accurate and frequent monitoring of quality of the milk. These tests can be extremely helpful in identifying the source of mastitis and assisting vets determine the best treatment for a cow.


Another on-farm tool for detecting antibiotic residues in milk is an immunochromatographic strip test, which provides results within minutes. This test can be conducted in a laboratory field or at the dairy with minimal equipment requirements. These tests are generally used by the regulators for milk receiving, shipping, and processing facilities. These tests are offered to dairy farmers veterinarian technicians, dairy truckers as well as testers of milk.


These tests identify the presence of antibodies attached to an antigen. The result is shown as a sequence of visual lines on a lateral flow test strip. The strips include an indicator line that indicates the test is functioning properly and two lines that indicate nondetectable, low, and excessive levels of the test within milk. These kits can be used to screen for commonly used antibiotics in milk, as well as aflatoxin.


Another milk test that is popular is the progesterone test which is used to determine whether the cow is in a state of open. However mzfoodtest be used to detect artificial inseminations since there are many other conditions than pregnancy that can cause low levels of progesterone between 19 and 23 days after the insemination.
