Anti-parasite treatment and blood biochemistry in raptor nestlings
We investigated the effects of parasite-removal on various blood clinical-chemical variables (BCCVs). BCCVs are indicators of health, reflecting e.g. homeostasis of liver, kidney function and bone metabolism. The study was conducted in Norway on chicks of two predatory birds: white-tailed eagle Hali...

We investigated the effects of parasite-removal on various blood clinical-chemical variables (BCCVs). BCCVs are indicators of health, reflecting e.g. homeostasis of liver, kidney function and bone metabolism.
