How bad is hydrated lime on your skin?

Hi, Milk Fans

It’s bad, it’s bad, it’s very,very bad.

Hydrated lime or Calcium Hydroxide reacts very fast with moisture and will even react with the moisture in your skin, so cover up hand and eyes.

However, once the reaction between the milk and the lime is completed and the milkpaint is dry, everything is safe again.

Sampling from a milktank

Hi, Milk Scientists

When doing sampling from a milk tank to determine milk composotion, it is important that you sample from either the top or the bottom every time, even if you think that the milk was stirred enough – be consistent.

Also be aware that a round tank will probably only need 5 minutes of stirring, but a long/rectangular tank will need 10 minutes, because the milk do not build up momentum in those tanks.

Hi, Milk People

Mastitis occurs when harmful bacteria enter the cow’s udder through the teat canal. Usually only one or two quarters are infected(cow has four quarters/parts to her udder).

Mastitis lowers milk production and the cow can become ill and die from it.

Cows get infected by other cows, the environment, like manure, soil and water.

Mastitis can be controlled by cleaning the udder before and after milking, by cleaning the equipment, by feeding the cows well and treating sick cows before things get out of hand.


Kind regards,

Long Weekend

Hi, Milkfans

As you can see, we had a good and decent long weekend here in South Africa.

Yes, even the milkman. 😉

I’ll soon be up to normal pace again.

Disadvantage Milk Paint

Hi, Milkfans

The only disadvantage I can think of is that the milk paint is a denatured protein stain and therefore will not be removed by normal solvents and even water-based solvents.

So no stripping – but you can paint it over. Not a problem when you paint the kids’ building blocks, because you won’t want to change their colour too often 😉

Kind regards,

Grazing Dairies Are Making More Money

Hi, Dairy Farmers

When it comes to household income, farming background and technology use, dairy farmers who use managed grazing aren’t all that different from farmers who operate more traditional dairy enterprises. In fact, they tend to be more profitable. That’s according to a new report from the UW-Madison Center for Integrated Agricultural Systems and Program on Agricultural Technology Studies. The groups compared production systems, technology, labor, performance and satisfaction with quality of life on grazing dairy farms and more conventional dairy farms.

Milk pH

Hi, Milkfans

The pH of milk should ideally be between 6.60 and 6.75.

When milk pH goes into the 6.5’s it is considered to be turning sour and above 6.80 there is reason to suspect mastitis(udder infection) or alkaline soaps – usually because of insufficient rinsing of tanks after cleaning.
