Medication & Forms Some brand names Some sources Average price Class of medicines Med may treat some (but not necessarily all) strains of these health problems Notes
Tylosin
Injectible liquid, soluble powder
Tylan 200 injectible (More concentrated so better injection for chickens), Tylan 50 injectible (Very diluted so less optimal for chickens)
Tylan soluble powder
Vets, animal health stores, vet suppliers, feed stores $17-60 Macrolides Infectious Coryza, Respiratory Mycoplasma, Necrotic Enteritis,
Ornithobacterium Rhinotracheale, Borreliosis (Spirochetosis)
Turkeys: Infectious Synovitis & Sinusitis Administer 5-7 days.
Tylosin may be less harsh on kidneys than some other meds.
Anti-inflammatory.
--Soluble form less effective on adults than young birds.
--May cause gastro-intestinal disturbance, & pain at injection sites. Birds may be reluctant to eat or move much.
For Soluble: Mix fresh water at least every 3 days. Don't mix with vinegar.
For Injectible: Active for 8 hours so best to split dose into 2-3 times/day. May cause soreness & minor muscle damage at injection sites.
Ways to help minimize problems: split up dose so you give only part of it at 2 or 3 different times each day, use 2 different injection spots each time, inject some in breast muscle & some under skin, give some of dose orally instead (tho there has been speculation that this might cause throat damage?? You can try putting needle-less 1-cc size syringe well down throat almost to crop to try to minimize risk.)
*Tylan 50: Up to 1.6 cc. (This is a lot of fluid--Need to
use methods above to help minimize problems.)
*Tylan 200: 1/2 cc. (Tylan 200 is easier on birds, because smaller amount of fluid)
--Can possibly give Tylan injectible orally instead or in addition to injection,
* Meat withdrawal 3 days. Injectible not recommended for meat birds.
Caution: Do not combine multiple Macrolides because reduces effectiveness.
