Estimation of protein requirement for maintenance in adult parrots (Amazona spp.) by determining inevitable N losses in excreta

Especially in older pet birds, an unnecessary overconsumption of protein – presumably occurring in human custody – should be avoided in view of a potential decrease in the excretory organs’ (liver, kidney) efficiency. Inevitable nitrogen (N)-losses enable the estimation of protein requirement for maintenance, because these losses have at least to be replaced to maintain […]
