1) I know why Baytril was withdrawn and I have cited the actual FDA documents. I never claimed there were harmful residues in meat or eggs. I simply stated that in the UNITED STATES it was a banned drug in EGG PRODUCING HENS. It is. End of story. Whether you agree with the science or not, it is the law. If you sell your eggs and have given your hens baytril, you are in violation. What you choose to do with that information is up to you--I just wanted to make sure people were aware the laws had changed. It's called informed consent, people. I'm not sure why this concept has been so completely misunderstood.
2) I have no idea why Tiamulin is getting introduced into this discussion. It works against M gallisepticum and M synoviae (if used with CTC). To my knowledge studies have not been performed to see if administration protects against infectious challenge. The big problem with any Mycoplasma is that while you can knock down the numbers of organism, it rarely goes away completely. In one study it had comparable MIC with doxycycline and tylosin--neither of which "cures" the bird.
3) We have effectively hijacked this thread from the poor chicken who was ill--perhaps we should move antibiotic discussions to another thread?
4) In re: veterinarians-from the flip side, most vet schools don't offer comprehensive avian programs let alone poultry based programs. There might be 1-2 weeks of rotation. In the clinic setting, birds require special equipment (humidifiers, incubators, perches, heaters etc) and medications. For poultry you have to keep track of withdrawal times and banned drugs--however much y'all might want to ignore them. There's also a money issue. Vet's have to pay rent and supplies and staff and overhead. Many poultry owners aren't willing to spend money on exams and fecals and tests and surgery ($300 and up). You can't pay for the equipment if you don't use it.
5) The internet is a blessing and a curse. There is a lot of misinformation or incomplete information or out of date information that gets passed around as gospel. (I keep getting a dog/cat vaccine e-mail that's been circulating for almost a decade. It talks about new vaccines on the horizon. Many of those vaccines have come and been pulled from the market or deemed non-core for years). When someone brings you new information you can take or leave it, but this dialog here isn't constructive or conducive to helping anyone or encouraging new people with information to share.
5) Are you guys always this tough on the newbies? I feel like I've been running defensive action since my 2nd post. I'm trying (unsuccessfully apparently) to help. While people in Europe or who work in zoos can ignore my baytril comments, there may also be some who do sell their eggs and aren't aware of the law change. I'm not sure it's fair to flatten me on the one hand for ignoring, (even though I wasn't), those who have pet birds and don't consume eggs and live outside the US while on the other hand ignoring those who DO sell their eggs in the US and need to know that information.
