Effects of 6/85-strain Mycoplasma gallisepticum inoculation alone at ten weeks of age or in conjunction with F-strain Mycoplasma gallisepticum inoculation overlays at twenty-two or forty-five weeks of age on the performance of commercial egg-laying hens.
The effects of 6/85-strain Mycoplasma gallisepticum (6/85MG) inoculation alone or in conjunction with a F-strain M. gallisepticum (FMG) overlay and its timing on the performance of commercial egg-laying hens were investigated. Control birds received sham inoculations at 10 wk of age. A second treated group of birds was inoculated with 6/85MG at 10 wk of age, a third treatment group of birds was...

Two trials were conducted to determine the effects of a prelay ts-11-strain Mycoplasma gallisepticum (ts-11MG) vaccination alone or in conjunction with F-strain M. gallisepticum (FMG) inoculation overlays at 2 different age periods during lay on the digestive and reproductive organ characteristics of commercial egg-laying hens. In each trial, the following 4 treatments were utilized: sham vacci...

متن کاملEffects of prelay ts11-strain Mycoplasma gallisepticum inoculation and time-specific F-Strain M. gallisepticum inoculation overlays on internal egg and eggshell characteristics of commercial laying hens.
Mycoplasma infections are pandemic in multiage layer chicken flocks, with Mycoplasma gallisepticum being the species of greatest concern to commercial egg producers. Live M. gallisepticum vaccines are presently being used to help control M. gallisepticum outbreaks. However, vaccination of layers with F-strain M. gallisepticum may adversely affect egg production. In the present study, 2 trials w...

Two trials were conducted to determine the effects of a prelay ts-11-strain Mycoplasma gallisepticum (ts-11MG) vaccination alone or in combination with subsequent time-specific F-strain M. gallisepticum (FMG) inoculations on the blood characteristics of commercial laying hens. The following 4 treatments were utilized: 1) sham vaccination at 10 wk of age, 2) vaccination of ts-11MG at 10 wk, 3) t...
