Injecting Antibiotics into Turkey Hatching Eggs to Eliminate Mycoplasma meleagridis Infection

Abstract

Hatching eggs from a commercial strain of turkeys infected naturally with Mycoplasma meleagridis were injected before incubation with various doses of tylosin, gentamicin, erythromycin, and chloramphenicol, individually and in combination. The antibiotics were inoculated into the albumen through a hole made in the small end of the egg. Gentamicin was the only drug consistently effective in reducing infection. With inoculation by the procedure described, the embryos tolerated several dose levels of gentamicin, tylosin, and erythromycin well.
