So the max dose of Tylan-50 would be 1/2cc per pound (so for a 4 pound bird it would be 2cc) twice daily? Should I give orally again or via injection? The little hen was getting .25 cc daily and the slightly larger was getting .5 daily, maybe I just wasn't giving a strong enough dose? I bought the Tylan-50 that I'm using in the spring of 2014 but I can't find an expiration date on it. Maybe it's expired and not as effective? It was stored in the original box in a cool and dry place.
The little hen who didn't have much of a reaction to the LA-200 looked better this morning. Her sinuses weren't as swollen and I didn't hear any sneezing which was encouraging. The bigger hen who had the reaction was still sneezing and shaking mucous from her beak. Now not only do I have to try get her better, but I have to figure out what to do with the inflamed injection site!
Both Tylan 50 and Tylan 200 can cause the same type of injection site reaction. I gave it by injection once and it happened, so will give it orally if I ever use it again.
The target Tylan powder dose is 50 mg per pound per day, so where I got that number.
Try the Tylan 50 at 0.5 ml per pound (4 pounds gets 2 ml twice a day).
