Hi
 My lambing is to start soon and I was clearing out all my sheep medical and other lambing related stuff. After disinfecting everything so it is ready for next weekend I also remembered I have colostrum and milk left from last year. They are in air tight containers and haven't been opened and when I checked it it still looks like new and smells like new, don't think that counts for much though. I was wondering if it is still safe to use for this years lambs or if I have to buy some new stuff as it isn't cheap?
