Abstract
Oxidative stress has been suggested to be affected by the growth and developmental period of animals, hence it may play an important role in the trade-off between growth and self-maintenance. In this study, I analysed the effects of two different diet regimes (high-quality diet, HQD; low-quality diet, LQD) on growth pattern, three components of the serum oxidative status (hydroperoxides, antioxidant capacity, and thiols), and serum corticosterone in nestling Pigeons (Columba livia Gmelin, 1789). The growth pattern was similar in the first week of life, after which HQD nestlings grew faster than LQD nestlings. Although there were no differences in serum corticosterone or thiol concentrations, serum oxidative damage increased faster over the nestling phase in HQD than LQD chicks. Serum antioxidant capacity remained stable over time in LQD nestlings and increased in HQD nestlings. This study provides evidence that different growth rates (induced in the absence of any physiological stress or prior nutritional deprivation) are accompanied by different serum oxidative statuses.
