NZ stock feed molasses??

[nzbourbonhead]

Come spring I can get bulk molasses real cheap from a cocky when he gets his vat filled as long as I have containers there for him to fill as his vat gets filled. I presume all stock feed molasses in nz are all imported from the one supplier so I am wondering if any one on this forum in NZ has or does straight molasses runs from stockfeed molasses. If so to what recipe and what sort of yield do you get?
