In a chicken group, I was instructed not to post about having given injectable tylan orally because it could cause internal damage. Any truth to this, supporting documentation/evidence?
I had no other option to give it orally. Everything was closed, I didn't have any needles and had to do something fast or loose a few chickens - At that point, I figured it was try it and hope they make it. To do nothing I was guaranteed to lose them. BTW, my chickens survived / recovered. Just concerned if there is long term damage I may have caused by administering orally.
I’ve given my geese Tylan orally a number of times. Some say it can cause necrosis at the injection sight, according to
@spcmoken ‘s vet Tylosin/ Tylan doesn’t actually cause the necrosis, it’s actually more likely that bacteria got into the wound during injection or after and that could be what causes the issue.
So far none of my birds have had adverse effects from taking Tylan orally, my gander Roxby has been given it fairly often compared to any of the others and so far I haven’t noticed any negative side effects.
Truthfully it’s more effective if given by injection but is still effective taken orally.
Tylosin can be safer than other antibiotics at high doses, though it’s known to be unsafe for ruminants.
Here’s an excerpt from Plumb’s veterinary drug handbook
overdosage/acute toxicity
“Tylosin is relatively safe in most overdose situations. The LD50 in pigs is greater than 5 g/kg orally, and approximately 1 g/kg IM. Dogs are reported to tolerate oral doses of 800 mg/kg. Long-term (2 year) oral administration of up to 400 mg/kg produced no organ toxicity in dogs. Shock and death have been reported in baby pigs overdosed with tylosin, however.”
I wouldn’t exceed the proper dosage for your chicken but it doesnt cause organ issues taken orally.
