Can gastriaid be used along side of pink powder?

  • Website Content Developer

Hi Wendy,

Thanks for your question.

I have spoken to NAF who assure me it will be fine to feed both together.

Hope this helps.

My horse has two feeds a day, can the daily dosage be split between the two feeds or is it best fed in one of them for the best results??? Plus he is unable to have alfa alfa a hes allergic, would it still be ok to use this??

  • Non-Executive Director

It is best to divide the daily dose between the 2 feeds he has each day. It should be fine for him with his Alfalfa problem.
