Keep in mind that Tylan injectable 50 and 200 are medications specifically for cattle and hogs, not for poultry. It is off label use in poultry and wont have egg/slaughter withdrawal times stated on the bottles as it does for cattle and hogs.

For the powder it says this:

Quote: Can you take a picture of that? That would be an excellent reference to have!

I am aware that chickens can be given tylan soluable, and like you stated, it has a one day withdrawal period.
The injectables can be given off label, much like most wormers.
And of course there's this link stating tylan injectables have a 7 day withdrawal:

Yes, but the only chicken/turkey withdrawal info I could find was for the powder, and it says do not use in layers.

If someone has a bottle of Tylan that states withdrawal time for eggs I would like to see a picture as it would be a great reference to have.

Abstract

Antimicrobials administered to laying hens may be distributed into egg white or yolk, indicating the importance of evaluating withdrawal times (WDTs) of the pharmaceutical formulations. In the present study, oxytetracycline and tylosin's WDTs were estimated. The concentration and depletion of these molecules in eggs were linked to their pharmacokinetic and physicochemical properties. Twenty-seven Leghorn hens were used: 12 treated with oxytetracycline, 12 treated with tylosin, and 3 remained as an untreated control group. After completion of therapies, eggs were collected daily and drug concentrations in egg white and yolk were assessed. The yolk was used as the target tissue to evaluate the WDT; the results were 9 and 3 days for oxytetracycline and tylosin, respectively. In particular, oxytetracycline has a good oral bioavailability, a moderate apparent volume of distribution, a molecular weight of 460 g/mol, and is lightly liposoluble. Tylosin, a hydrosoluble compound, with a molecular weight of 916 g/mol, has a low oral bioavailability and a low apparent volume of distribution, too. Present results suggest that the WDTs of the studied antimicrobials are strongly influenced by their oral bioavailability, the distribution, and the molecular weight and solubility, and that these properties also influence the distribution between the egg yolk and white.

Good link Kathy and I'm bookmarking. However, I believe it's for soluables, not injectables.
