SORRY I AM LOGGING IN AFTER THE FACT.........
I can only speak from experience not as an educator.
We buy MOLDY HAY intentionally. We can get a 3 strand 75# bale for less than 3 bucks. We use it to bed our stock in cold weather and especially Sow's delivering piglets/nesting new born. We currently have 3- 125# feeders bedding in it as well as 3 litters from 3 Sows, 2 boars and a resting Sow.
I am not saying it's not the mold at all.. Maybe a different kind of mold we have here in N Florida.
Just that to us is something we have not witnessed personally.
When was the last Ivermectin treatment?
You can treat them orally with 1cc per 100#.
Inject it into a bread ball. I do this 30 days before process.
ALMOST EVERY TIME we feed FRESH GREEN ALFALFA.. They chuck it up.. like a cat with a hair ball.
I am glad you said they are doing better..
