The immune responses following vaccination and resistance to diseases were compared in male and female meat poultry breeders of the same flock. Female poultry breeders maintained antibody titres to Newcastle disease virus and infectious bronchitis virus up to the fifty-fifth day following vaccination, whereas those of the males declined significantly over the same period of time (P < 0.05). In the same flock, outbreaks of Gumboro disease (60 to 62 days of age), coccidiosis (68 to 74 days of age) and aortic rupture (99 to 112 days of age) produced significantly higher losses in males. Following vaccination against fowl pox by the wing web method, 96.7% of females had a vaccine reaction (vaccine take) compared to none of the males. Immune injuries, following vaccination, were observed in 85% of the males compared to none of the females. The immune injuries included appearance of facial papules, vesicles, and reddish brown to black scabs.
对同一鸡群中的雄性和雌性肉种鸡接种疫苗后的免疫反应及抗病能力进行了比较。雌性种鸡在接种疫苗后直至第55天，对新城疫病毒和传染性支气管炎病毒保持抗体滴度，而雄性种鸡的抗体滴度在同一时期显著下降（P<0.05）。在同一鸡群中，法氏囊病（60至62日龄）、球虫病（68至74日龄）和主动脉破裂（99至112日龄）的爆发在雄性鸡中造成的损失显著更高。通过翼膜法接种鸡痘疫苗后，96.7%的雌性鸡出现疫苗反应（疫苗接种成功），而雄性鸡无一出现。接种疫苗后，85%的雄性鸡出现免疫损伤，而雌性鸡无一出现。免疫损伤包括面部丘疹、水疱以及红棕色至黑色结痂的出现。
