Abstract
Mortality due to nephritis and uric acid diathesis was observed during the fall and winter in captive willow ptarmigan. The present study examined how feed protein concentration influences feed and water consumption, plasma uric acid concentration, and mortality due to nephritis and uric acid diathesis in captive wrillow ptarmigan. An increase in feed protein concentration from 14 to 24 % resulted in reduced feed consumption and increased plasma uric acid concentration. Mortality due to nephritis and uric acid diathesis was not influenced by variations in feed protein concentration, but an admixture of 14 % grass meal to the diet reduced the incidence markedly.
Sammendrag
Nyrebetennelse og urinsur diathese forekom om høsten og vinieren hos liryper i fangenskap. I dette arbeidet er det testet hvordan forskjellige proteinkonsentrasjoner i fóret influerer på fór- og vann-opptak, urinsyrekonsentrasjon i plasma og mortalitet forårsaket av nyrebetennelse og urinsur diathese hos liryper i fangenskap. En øk-ning i proteinkonsentrasjon fra 14–24 prosent resulterte i nedsatt fóropptak og økt urinsyrekonsentrasjon i plasma, mens mortaliteten pga nyrebetennelse og urinsur diathese var upåvirket. En tilblanding av 14 prosent grasmel til fóret reduserte forekomsten av nyrebetennelse og urinsur diathese betraktelig. Årsaken til dette er foreløpig uklar.
