Abstract
This experiment has not been completed. The data shown were obtained at 12 weeks. Eggs from a breeder flock with a known history of Mycoplasma gallisepticum infection were dipped in a solution containing a combination of 2800 ppm Tylan and 2000 ppm Neomycin before incubation. The eggs were first dipped in warm water (98°F) for 5 minutes and then into the cold (38°F) antibiotic solution for 10 minutes. Batches of 50 eggs increased in weight 6 to 18 grams from this treatment, thus showing an average uptake of 0.68 mcg of tylosin and 0.49 mcg of Neomycin of the eggs were 3 weeks old when set and the balance 1 week. Therefore, the old and young eggs were set separately. Results would indicate that the age of the eggs and dipping affected 7-day fertility and hatchability. Last year the eggs were dipped using a vacuum method
