(1) The effect of infections with Dermanyssus gallinae (poultry red mite or chicken mite) and Ascaridia galli (roundworm) on the behaviour and health of laying hens was investigated. (2) Six groups of 15 pullets (Isa Brown) were kept in indoor pens from 18 weeks of age. Two groups were artificially infected with D. gallinae, two groups with A. galli and two groups were kept as uninfected controls. The hens were observed for behavioural reactions and physiological changes (weight gain and various blood variables) to the parasitic infections. (3) Infections with D. gallinae resulted in reduced weight gain, anaemia and even death of some of the hens. Behavioural changes were also observed, as the mite-infected hens showed higher self-grooming and head scratching both during the day and night. (4) A. galli resulted in a lower weight gain but no significant changes were seen in blood variables or behavioural activities.
(1) 研究了鸡皮刺螨（家禽红螨或鸡螨）和鸡蛔虫感染对蛋鸡行为和健康的影响。(2) 从18周龄起，将六组每组15只小母鸡（伊萨褐鸡）饲养在室内鸡舍中。两组人工感染鸡皮刺螨，两组感染鸡蛔虫，两组作为未感染对照。观察母鸡对寄生虫感染的行为反应和生理变化（体重增加和各种血液指标）。(3) 感染鸡皮刺螨导致一些母鸡体重增加减少、贫血甚至死亡。还观察到行为变化，因为感染螨虫的母鸡在白天和晚上都表现出更高的自我梳理和抓头行为。(4) 感染鸡蛔虫导致体重增加较低，但血液指标或行为活动未见显著变化。
