1．在两个大山雀种群中进行了育雏规模控制实验，以评价饲养不同数量雏鸟对亲代健康状况的影响。2．育雏扩大导致异嗜性：淋巴细胞比值升高，外周血淋巴细胞数量减少，表明繁殖努力增加导致免疫抑制。3．血细胞比容随育雏扩大而增加，表明在工作负荷增加期间对血液携氧能力提高的需求的反应。4．亲本体重显示出随育雏扩大而下降的趋势。5．未检测到巢大小控制对白细胞总数、嗜异性计数、嗜血杆菌血液寄生虫感染强度或血浆蛋白的影响。6．与城市鸟类相比，在农村栖息地繁殖的大山雀的健康状况指数对雏鸟大小的控制更为敏感。
1. A brood size manipulation experiment was performed in two Great Tit (Parus major L.) populations in order to evaluate the effect of raising different numbers of nestlings on parental health state.2. Brood enlargement resulted in elevated heterophile:lymphocyte ratios and decreased lymphocyte number in the peripheral blood, indicating that increased reproductive effort causes immunosuppression.3. Haematocrit increased in response to brood enlargement, suggesting a response to the requirement of elevated oxygen-carrying capacity of the blood during increased work load.4. Parental body mass revealed a tendency to decrease in response to brood enlargement.5. No effect of brood size manipulation on total leucocyte count, heterophile count, intensity of Haemaproteus blood parasite infection or plasma proteins could be detected.6. Health state indices were more sensitive to brood size manipulation in the Great Tits breeding in a rural habitat than urban birds.
