I can’t find much information on the websites of major retailers about the farms they source their milk from. Most of what is available makes reference to high welfare standards but lacks any real detail. Similarly, when it comes to how the cows are managed and, in particular the contribution from grazing, there is little substance. The extract below from www.tescofarming.com states that “cows eat grass in the summer and preserved grass in the water……..”.

I’m not sure when the cows are “in the water” – perhaps they mean in the winter? However, of more interest is the statement that cows eat grass in the summer. Do they? I wonder if all the cows supplying milk to Tesco eat grass in the summer and if they do, how much do they eat and for how many days of the year?

I’m not singling out Tesco for closer scrutiny – all of the major retailers seem to present images of herds of cows grazing lush pastures when promoting their milk. But, in reality, are they really demanding that suppliers graze their cows for a significant period of the year? I hear some supermarket milk contracts state that cows must go outside for part of the year but, in many instances, this may be for no more than a few weeks when the cows are dry (not producing milk).

Retailers should not mislead consumers by presenting images of cows at grass if they are not selling milk from herds that spend a significant part of their productive life grazing grass. If we are to instil real value in our milk then lets make sure that consumers have a clear understanding of how it is produced.

Cows eat fresh grass in the summer and preserved grass in the water, such as silage (pickled grass) and hay (dried grass).
