Yet to see any effects, initial dosing is high so I may have purchased two tubs as the first isn’t going to last long.

Giving sporadically


Can I give this to my pony a few days before a comp and do not give permanently?

  • VioVet Staff

Yes this product is FEI/Jockey Club Legal so is safe to use around competitions. You should follow the dosing guidance in regards to when to feed. The loading period is 3 to 10 days of a higher loading dose so it is recommended to be beyond the loading period and into the maintenance period for the best effects to be seen.
If you ensure a good loading period is carried out and your horse has just started the maintenance dose for when the competition starts then this should be appropriate.

Can gastriaid be used along side of pink powder?

  • VioVet Staff

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??

  • VioVet Staff

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.
