When 23-, 35-, and 49-week old Ideal 236 White Leghorn hens were infested with the chicken body louse, Menacanthus stramineus, percentage egg production 12 weeks later had decreased by 16, 34, and 46%. Meanwhile, the average hen weight had decreased by about 85, 300, and 450 grams compared with unifested control hens of the same age. There were also significant decreases in clutch size and feed consumption of the infested hens. All the decreases correlated with populations of lice.
当23周龄、35周龄和49周龄的理想236白来航母鸡感染鸡体虱（Menacanthus stramineus）后，12周后的产蛋率分别下降了16%、34%和46%。与此同时，与未感染的同龄对照母鸡相比，感染母鸡的平均体重分别下降了约85克、300克和450克。感染母鸡的窝蛋数和采食量也显著下降。所有这些下降都与虱子数量相关。
