I would suggest getting some probiotics also.
Another thing I should mention on the chance it rears it’s ugly head, coccidia can predispose the digestive tract to enteritis/clostridium infection.
Metronidazole can treat that, from my own expierience metro in conjunction with Tylosin is highly effective when you don’t know what strain of clostridium it is and your vet is less than helpful.
Tylosin works best by injection however, in my state I can’t get the liquid without a prescription so I use the powder

given orally 4 or 5 times daily. Putting it in water doesn’t seem to work because the taste is so harsh they won’t drink it.
NOTE: Tylosin should not be given to horses.
Metronidazole can be purchased as fish antibiotics.
