Broiler breeder chickens were exposed to avirulent Pasteurella multocida at 14, 22, and 34 weeks of age either by stick wing 1 to 3 times or subcutaneously 3 times. Fowl pox vaccine was mixed with the first P. multocida exposure in some groups. Exposure did not impair egg production or hatch of fertile eggs. Challenge with pathogenic P. multocida serotype 1 at 68 weeks indicated that exposure to avirulent P. multocida 2 or 3 times provided better protection than 1 exposure. Mixing fowl pox vaccine with the avirulent P. multocida did not reduce immunity to fowl cholera or fowl pox.
肉种鸡在14、22和34周龄时通过翅刺接种1至3次或皮下接种3次接触无毒多杀性巴氏杆菌。在一些组中，鸡痘疫苗与首次接触多杀性巴氏杆菌混合使用。接触并未影响产蛋量或受精卵的孵化率。在68周龄时用致病性多杀性巴氏杆菌血清型1进行攻毒试验表明，接触2次或3次无毒多杀性巴氏杆菌比接触1次提供了更好的保护。将鸡痘疫苗与无毒多杀性巴氏杆菌混合使用不会降低对禽霍乱或鸡痘的免疫力。
