BLOOD BIOCHEMICAL PROFILE IN DOGS AND CATS UNDER DIFFERENT FEEDING DIETS

Abstract

Foram determinados os parâmetros de bioquímica sanguínea em 50 cães e 25 gatos
sadios submetidos a três regimes alimentares: ração comercial, comida caseira e alimentação mista
(ração e caseira). Os cães e os gatos alimentados com regime misto apresentaram níveis sanguíneos
elevados de glicose e de colesterol, sugerindo um consumo de alimentos calóricos acima dos
requerimentos e um maior risco de obesidade. A ingestão de proteínas na alimentação caseira
parece ser restrita, considerando-se as baixas concentrações de albumina e/ou uréia sanguíneas
nos cães e nos gatos. Baixos teores de cálcio foram encontrados nos cães de alimentação não
concentrada. Os gatos com alimentação caseira podem estar consumindo quantidades baixas de
minerais revelado pelos menores teores sanguíneos de cálcio, fósforo e magnésio.

Abstract

The aim of the present work was to carry out a study on the variation of the blood
chemistry constituents of dogs and cats subjected to different feeding diets. Blood samples from
50 healthy dogs and 25 cats were used to study the effect of feeding diets with commercial ration,
homemade or mixed (concentrate and homemade) on their blood biochemical profile. Both, dogs
and cats, fed with mixed rations showed higher glucose and cholesterol blood levels, which could be
suggestive of a high caloric intake and a risk of obesity. Intake of proteins in animals with homemade
feed seems to be low considering concentrations of plasma albumin and/or urea in dogs and cats.
Low levels of calcium were found in dogs with non-concentrated feed. Cats with homemade feed
could have low intake of minerals considering the lower levels of calcium, phosphorus and magnesium
observed.
