Hay allergy?

[Hamandsammich]

Does anyone have experience of a pig with allergies, such as to hay?

Our sow occasionally makes a hooting kind of sound, like she needs to clear her nose. This happens for a short while, then she sneezes and it goes away.

She has no other symptoms, no crusty nose or eyes, no discharge. She eats normally, popcorns, behaves like normal. The hooting happens probably once a week or less. I think it is possibly when she's had her face in fresh hay but can't be sure. I got a hay bag so that she couldn't climb inside the hay pile anymore, but the hooting still happens occasionally.

Does anyone have experience of a pig with allergies and can advise how they treated it?

Thanks in advance

They have narrow airways and any dust which gets into the nasal passages will cause sneezing. They can’t breathe through their mouths so if there is dust in her nose then you will hear it. When she sneezes it clears.
This does not mean she has an allergy.
Could you perhaps try to find a less dusty brand of hay

Are the piggies living inside or out? If
they are inside any fragrance/ air fresheners can cause allergies. Are they bedded on fleece or shavings? Again with fleece it could be washing powder, shavings could be a bit dusty. With Hay are you using dust extracted hay?
One of our pigs was Sneezing a lot when we got him but once we changed our washing powder to no bio and took away an air fresher he stopped! We also use Hay box hay which is dust extracted so that helps!
