Dear Christina, if we are talking about the amount of water consumption for a large farm, it is approximately 115 liters per dairy cow per day (taking into account drinking, hygiene and sanitary treatment of equipment). However, take into account the hot climate, which means additional water costs for animal cooling

Dear Cristina,

Please refer the article given in the link below. In addition to that, you have to incorporate the water requirenment in extreme hot condition as mentiond by Roman

Dear Christina,

You could find the water footprint for many animal products (including different milks) and countries (including Israel) in this link:

https://waterfootprint.org/media/downloads/Report48-Appendix-V.zip (An excel spreadsheet with the info you need)

from the documentation of this interesting paper:

Mekonnen, M.M. & Hoekstra, A.Y. (2012) A global assessment of the water footprint of farm animal products, Ecosystems, 15(3): 401–415.

Good luck,

Pedro L. Lomas.

Roman Mylostyvyi Thank you very much! But 115 liter a day sounds too less. Also Water in animal feed has to be taken into account.

A. G. Piyal Aravinna Thanks alot! I just requested that article. Sounds promising!

Pedro L. Lomas Very nice source, thanks alot. I just read it. But do you maybe know why there is water use for a grazing system in Israel is mentioned? Because due to my knowledge there is no grazing for dairy cows at all. And I am not sure if it is for raw milk or already processed milk.

Dear Christina, maybe you will find useful information in the materials of the CIGR (International Commission of Agricultural and Biosystems Engineering)

Roman Mylostyvyi thank you for your advice! I will have a look at it.
