Richard, I was having trouble with sheep liver/uterine/muscle RNA extractions. 
I assume though you are looking at extracting mRNA, not total RNA as I was. 
Try using the "Bresatec" RNA extraction reagents eg. Ultraspec or RNAzol B. 
They seem to reduce yields slightly but clean up all DNA/Protein 
contamination. From here I would guess that a CsCl prep to separate the mRNA 
would be the way to go.
