Global Milk Price Conversion

Milk costs reportable inside the media will be complex and deceptive info for farmers, the dairy trade, and the general public. The premise of measure and reportage varies extensively inside many international locations, let alone when forex is taken into consideration.

Mostly milk value is reportable as a price per measure or weight of milk. For instance: cents per cubic decimeter (cpl); {dollars} per hundredweight ($/cwt); or euro per 100 kilos. The foremost downside with these value bases is that precise monetary system imagination for milk are sometimes for the elements of fats, protein and different solids – only a couple of dairy processors invite water! It is better to know the composition of the milk and this composition modifications from farm to farm and from nation to nation. There isn’t a one customary composition with regards to evaluating native and worldwide costs.  Introduced listed below are a number of the components that have to be taken into consideration when making comparisons.

Global Milk Price Conversion

Foreign money:

That is an apparent subject even so consideration must tend to a alternative between:  the present every day fee; the annual common conversion fee; the weighted common conversion fee.  Within the last mentioned case the forex trade fee ought to to be weighted to the timing of monetary system imagination to farmers.

Fats and Protein Composition:

  It’s regular for farmers to be paid on the premise of the milk fats and protein composition.  This will have a dramatic have an effect on on the milk value when expressed in cpl.  So for example the cpl milk value for a jersey cow with excessive milk elements will be greater than 50% greater than a fresian / Holstein-Friesian cow. 

Typical composition of cows milk inside the main world dairy exporters are:  Europe – 4.2% fats, 3.4% protein; USA 3.7% fats, 3.0% protein; New Zealand – 4.7% fats, 3.7% protein;  Australia 4.1% fats, 3.3% protein. 

So as to add to the confusion, reportable USDA milk costs in $/cwt are primarily supported a fats composition of three.5% and the Eurostat milk costs are primarily supported 3.7% fats. 

There isn’t a customary for Australian and New Zealand milk value and the most secure measure of native value is when expressed as $ / kilo of milk solids ($ / kg MS).  Milk solids is distinct because the sum of fats and protein measure in milk.

Mass or Quantity Measurement: 

In addition to the fats and protein composition of milk you additionally must know whether or not the check measure is expressed as mass / mass (eg. kg / kg) or mass / measure (eg. kg / cubic decimeter).   The standard density of milk is near 1.03 grams / cubic decimeter so an error right here can have an effect on the milk value calculation by 3%.

True or Crude Protein:

Crude protein is an estimate of milk protein composition primarily supported N measures (sometimes by Kjeldahl N testing).  The milk protein content material is deliberate from a world customary issue of Nitrogen x 6.38.  

True protein is an estimate of the particular milk protein primarily supported graduated roughly infrared measure.    The distinction between crude and true protein equates to what’s termed “non protein N” (NPN). 

It’s estimated that true protein measure will give a end result 0.1 – 0.2% decrease than crude protein.   This will have an effect on the calculation of milk value by as very a great deal like 5%.

Within the US and Australia milk protein content material is often reportable as true protein whereas inside the EU and NZ, extra typically crude protein is used.

Instance Calculation:

Right here is an instance of the way you would possibly convert a reportable milk value from one nation to a different taking account of the components above:

A US farmer will get paid $US 11.50 / cwt for milk with a composition of three.7% fats and three.0% true protein on a mass / mass foundation.

A New Zealand farmer necessarily to know what this equates to in $NZ / kg MS with the milk solids being capable fats + crude protein. Assuming an trade fee of $NZ 1.00 = $US 0.70, and that crude protein = true protein + 0.15%, the calculation is as follows:

$US 11.50 / cwt = $NZ 16.43 / cwt

Milk composition = 3.7% fats + (3.0 + 0.15) % crude protein = 6.85% milk solids mass / mass

1 cwt milk / 220.4 = 45.4 kilos

$NZ $16.43 / cwt / 45.4 / .0685 = $NZ 5.28 / kg MS CP (crude protein)

For an Australian Farmer there isn’t any want to regulate for crude protein – milk solids = %3.7 + 3.0% = 6.7%. Assuming an trade fee of $AU 1.00 = $US 0.87:

$US 11.50 / cwt = $AU 13.22 / cwt

$AU 13.22 / cwt / 45.4 / .065 = $AU 4.35 / kg MS TP (true protein)

A UK farmer necessarily to know what that is in pence cents per cubic decimeter at their typical milk composition of 4.2% fats and three.4% crude protein (~ 3.25% true protein). This query is a bit more durable as a result of we do not know the worth of the soul fats and protein elements. The most effective we are able to do is assume that the worth of milk solids is identical. That may give a fairly shut approximation if the ratio of fats to protein is comparable in each instances. So assuming: $US 1.00 = 63 English pence

$US 11.50 / cwt = 724.5 pence / cwt (7.25 English kilos / cwt)

724.5 pence / cwt / 45.4 = 16.0 pence / kilo

16.0 pence / kilo x 1.03 = 16.4 pence / cubic decimeter

That is yet the value at a composition of three.7% fats and three.0% true protein. To get an estimate on the element pricing of the eu farmer apply the relative ratio of complete milk solids:

16.4 pence / cubic decimeter x (4.2 + 3.25) / (3.7 + 3.0) = 18.2 pence per cubic decimeter.

Over on the European continent they suppose in euros / 100 kg of milk. We’ll take a crosscut right here and convert from pence per cubic decimeter to Euros / 100 kg assuming the identical milk composition because the UK farmer. With an trade fee of 1.00 euro = 92 English pence:

18.2 pence per cubic decimeter = 19.8 euro / 100 cubic decimeters

19.8 euro / 100 cubic decimeters / 1.03 = 19.2 euro / 100 kg
