Method of determining remaining milk when taking off cream

Posted on May 11th, 2006 by Leon the Milkman.

Hi, Dairy Farmers/Processors

I get asked a lot how much milk remains after cream is taken off - hope this calculation helps. If I did it wrong - please let me know Theoretically:
1000 liters of milk(you start off with)40% fat in resulting cream(assume this is the fat % of your cream) Just substitute your cream’s tested fat % in here.

Problem 1:
What volume of milk remains when I take 3.8% butterfat milk down to 3.3%?(FULL CREAM)

3.8% - 3.3% = 0.5%

0.5% x 1000 liters = 500 parts of Fat removed

500 parts ÷ 40% cream = 12.5 Liters of cream

1000 – 12.5 = 987.5 liters milk remaining

Problem 2:
What volume of milk remains when I take 3.8% butterfat milk down to 2%?(LOW FAT)

3.8% - 2% = 1.8

1.8 x 1000 = 1800

1800 ÷ 40 = 45

1000 – 45 = 955 liters of milk remaining

Problem 3:
What volume of milk remains when I skim milk completely?

3.8% - 0% = 3.8%

3.8% x 1000 liters = 3800 parts of Fat removed

3800 parts ÷ 40% cream = 95 liters of cream

1000 – 95 = 905 liters of milk remaining

Dairy Cows satisfy sweet tooth

Hi, Cow Fans

Yes, cows are doing a good thing again. Besides satisfying their own sweet tooth, they are diverting tons of organic material from organic wate dumps.

Organic or not?

Hi, Milk Fans

Seems that some guys are trying to pass some milk for organic - and they want us to trust them. You are hurting us all - stop that!

How bad is hydrated lime on your skin?

Posted on May 6th, 2006 by Leon the Milkman.
Categories: Milk Paint.

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.

P.S. Here is a very informative link about lime:

Sampling from a milktank

Posted on May 5th, 2006 by Leon the Milkman.
Categories: Dairy Science.

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.

Mastitis

Posted on May 4th, 2006 by Leon the Milkman.
Categories: Cows.

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,
