Dear Dairy experts,

Almost after 4th day of calving, milk color turns from yellowish to white. How could we find out the present draining milk is Colostrums or Normal? Because, some cow gives till 8, 9 days as colostrums milk. Some cow turns 4th day to normal milk. Even after 5th day the colostrums & normal milk shows same white color. But if, we mixed together (normal + colostrums), the whole milk has been spoiled? What is the solution to avoid such a spoil? Right now I am identifying by heating (100ml) the milk

How could we differentiate apart from heating? Please guide me

Thanks in advance

Even I use the boiling method to identify as rules in karnataka milk federation state that you cannot send milk for around 14 days after delivery whereas HF cow milk turns normal as soon as 5th day sometimes. Then what to do with 15-20 lts milk?

Boiling seems to be simplest solution as it provides result without any complication.

Hi Shankar,

Thanks for your reply. But this will help to find the quality of Colostrum.
This will show the quality of colostrum is poor even after 8 or 9 days. But this will not indicate milk is pure or colostrum.


Thanks

Hi Murali,

Thanks a lot for your reply. I am doing the same COB test. But also looking for other alternate method.

Thanks a lot

Dear all,

Using Alcohol test, we can find out the quality of milk.

Mixing of equal volume of Milk (10 ml) and 68% Ethyl Alcohol (10 ml).
If the milk curdles, it is considered unsatisfactory and is rejected.
