Toxemia da Prenhez em ovinos: revisão de literatura

Abstract

The toxemia of pregnancy is a metabolic disease that affects animals more specifically goats and sheep production, presenting usually secondary to hypoglycemia. It is associated with multiple gestation fetus or too large, a fact that leads to a reduction of ruminal space in the last weeks before birth causing the animals ingest less food by changing their metabolism so that brings increased levels of ketone bodies in the blood. Considered multifactorial, may occur as a result of starvation, obesity, food stress, environmental factors or transport managements as trimming and shearing, sudden change in temperature or exposure to very hot or very cold places. Treatment depends on early diagnosis, since the animals affected in serious condition does not respond well to therapy. Therefore, the best way to prevent the occurrence of this disease are the preventive measures, particularly with regard to nutrition, where a diet with adequate nutritional level during pregnancy is necessary.
