Treatment of normal male Leghorn chickens with doses of estradiol ranging from .1 to 1.0 mg per week caused only a slight increase in resistance to infestation with northern fowl mites. The resistance phenomenon did not increase linearly with estradiol dose. Pullets were initially resistant to mite infestation; however, susceptibility was noted to increase markedly near the time of initial egg-production. These data indicate that sex hormones may be related to mite resistance in chickens, but that estrogen alone is probably not responsible for the difference in mite susceptibility between male and female birds.
每周用0.1至1.0毫克剂量的雌二醇处理正常雄性来亨鸡，只会使其对北方鸡螨感染的抵抗力略有增加。抵抗力现象并非随雌二醇剂量呈线性增加。小母鸡最初对螨感染具有抵抗力；然而，在开始产蛋时易感性明显增加。这些数据表明，性激素可能与鸡对螨的抵抗力有关，但仅雌激素可能并非导致雄鸡和雌鸡对螨易感性差异的原因。
