Sampling of the milk was made direct from the expansion tank, so after the milking. The pH has reached very high and very alkaline levels, around 11 to 13. The incidence of mastitis is low (low somatic cell count) and in some cases kept in compost barn.
Dr. Santose, milk is a buffer solution, so it is very surprising and something unusual as well as difficult to believe. Normally the pH of the cows milk ranges between 6.5 and 6.7. Only mastitic milk pH you may expect sometimes more than 6.7. I think, you better check your pH meter and rest assure.
Maybe the milk was contaminated with a strongly alkaline cleaning agent.
Yes, I think so.
You have to calibrate carefully your pH meter or check if it works well.
In addition, you have to check if there is some contamination or residue coming from cleaning process or system.
Alkiline milk is an indication of udder infection or ontamination
make sure that the cow does not have Mastitis ( sub clinical )or any other problem
Make sure that no possibility of contamination during handling. The PH should not be more than 7.
Developed acidity is due to lactic acid produced by the action of milk bacteria on lactose.
Significant buildup of thermoduric organisms in milk residue can influence the bulk tank acidity and are an indication of a persistent cleaning failure that can result in high SH levels.
Old cracked rubber parts are also associated with higher levels of thermoduric bacteria.
Possible causes -
1. Сalibration of pH meter
2. Alcaline cleaning agent
3. Mastitis??
4 Sodium bicarbonate or other chemicals
If the problem turns out to be internal, ie; cow related and not outside contamination, then we could have a solution. This blog gives some details: http://www.torsionfield.co.uk/blog/quantum-physics-in-agriculture
We are looking to collaborate with researchers to test Torsion Field structured water in many applications in dairy, feeding structured water to the cows, TF structuring the milk itself (longer shelf life) as well as cleaning the milking shed. We believe it may help reduce cross contamination of Bovine TB. my email is [email protected]
Many valid answers are given by different experts in this line. I think cows may be suffered from Mastitis, Due to heavy use cleaning agents and instruments itself and containers.
Generally Alkaline CIP milking system products' PH levels are 13-14. So absolutely you should check your results.
About how much Alkali (a strong one) is required to increase pH of about 7,000 lit Holstein- Frisian cow milk to 10 or 11?
Two possibilities: there was something wrong with the pH measurement or the milk was contaminated by a strongly alkaline sanitizer.
