Production cut no help to poor milk prices
Hi, Milk Fans
Scottish dairy farmers have rejected persistent claims that they could get a better farmgate price by cutting production.

Low-fat dairy helps blood pressure
A new study suggests that milk and other dairy products, especially low-fat varieties, can help reduce blood pressure. Those who ate the most dairy cut the risk of high-blood pressure by 54 percent, according to the research published in the journal Hypertension.

Nitrogen in milk
Hi, Dairy Scientists
The nitrogen in milk is divided into the protein in casein and whey protein. There is also a small percentage of NPN(non-protein nitrogen), which is in itself divided into Urea and non-Urea nitrogen.

Balanced Milk
Hi, Milk Fans
You know why I always say milk is balanced?
Well if you look at the composition of cow and goat milk, you will see that the fat, protein and lactose(carbohydrate) is more balanced than in almost any other food. This helps regulate blood sugar and gives you all-round nourishment throughout the day.

Comparing cow, goat and soy milk
The best way to approach this subject is with an open mind and also to compare the different products point for point, e.g. the fat percentage and composition between all the milks, and doing the same for every component.
Another important consideration in this case is the fact that we are using milk as removed in the natural soy milk method that has been used for centuries. This was done to give a true indication of the soy, because different manufacturers adapt the soy to their own standards; adding less or more sugar, fat and other additives.

Method of determining remaining milk when taking off cream
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

Raw Milk Calories
Hi, Milkfans
Raw milk does not have less or more calories than the pasteurized version of the same milk. Full cream milk having about 620 calories per Liter, raw or pasteurized.
Although some of the nutrients are destroyed ( small percentage ) during pasteurization, pasteurized milk is still safer than raw milk. Although I have drunk my fair share of raw milk, I see the results of analysis on that milk and therefore feel comfortable drinking that specific farm milk.

Human Milk Composition
Hi, Guys
Yes, I do get a lot of questions like this 😉
Well, at the moment I am testing human milk for a project by a local hospital and I must say that I have never seen such a variance in composition compared to the cow and goat’s milk that we test as well.
I think this has a lot to do with cows being much more set in a routine and eating the same diet every day – haha, sorry to you women out there for making these comparisons, but we really get asked these things a lot.
The average composition of macronutrients in human milk is about 1% Protein, 4% Fat and 7% Lactose. If you take different milks you’ll see that the nutrients present are much the same and in most the ratios are also the same between nutrients, but the concentrations differ the most.
Sheep’s milk for example is much more nutritious than cow’s milk and contains about twice the calories.

Density vs. Specific Gravity of Milk
By determining the specific gravity (SG) of milk the following information can be obtained.
• An indication of adulteration of milk with added water.
• If the fat percentage is available the solids-non-fat (or total solids content) of the milk can be calculated.
- Definition
Specific gravity is the relationship of the mass of a specific volume of a substance to the mass of an equal volume of water at the same temperature.
Density is measured as mass per volume (g/ml) at a specific temperature.
The specific gravity of milk at 20 °C is ± 1.030 and is determined by the relative proportions of fat (SG = 0.93), water (SG = 1.0) and solids-non-fat (SG = 1.614).
