Pregnancy toxemia is a disease that occurs in small ruminants (sheep and goats) during the last weeks of pregnancy due to frequent twin pregnancy. Females in their final third of gestation that carry multiple fetuses and are unable to consume energy for their metabolic demand, due to inadequate diet, are usually affected by this disorder. In addition, animals with a disease that occurs in the course of another disease or environmental stress can also be affected. It is characterized by energy disruption generated by the drop in glucose concentration together with an excessive increase in the concentration of ketone bodies in the blood. In this way, there is a greater demand of the fetus for glucose, exceeding the energy in the diet and consequently increasing lipolysis and elevation in the synthesis of ketone bodies, which will lead to disorders of metabolic homeostasis. This disease is characterized by apathy, dyspnea, anorexia, rumen atony, amaurosis, muscle tremors, prostration and difficulties in walking, and may progress to death. The objective was to carry out a literature review on small ruminant toxemia: etiopathogenesis and prevention.
