Bread-Bakers v105.n036.14

I have noticed that when I use our own fresh milk from our own cow, 
"Milky Way", the texture of my 7 grain bread changes...not for the 
better.  It seems to fall apart on slicing.  The texture is better 
when I use dry milk and water. Can anyone explain?  I also do not add 
canola oil as the milk is very rich with Jersey cream.
