milk temperatures, goat vs cow

[rosawoodsii]

In most of the recipes I've found on goat forums, instructions are to heat the milk to a lower temperature than for cow milk.  Does anyone know why this is, and whether it's a standard 2° difference or whether the difference would increase as the cheese making temperature changes?  That is, milk that's prepared at 88° for cow milk is listed (in parentheses) as 86° for goat milk, but I've also seen recipes that have a 4° difference when the temperature at starting is, say, 94°.

Is this arbitrary? Necessary? How would it change the cheese?

Does anyone have an answer to my question?  Anyone else out there make cheese with goat milk rather than cow milk?

 I think various books talk about it and I too have seen a range of temps.  I don't worry too much about it but if I'm thinking about it I actually use about a 5 degree difference....cooler for goat milk.  Hopefully someone who knows more than I will answer.
