The objective of this work is to perform a clinical epidemiological study on the occurrence of pregnancy toxemia in ewes treated in Bovine Clinic, Campus Garanhuns / UFRPE in the period January 2006 to December 2010. The assessments in epidemiological studies (included factors such as time of year, race, age, number of calving, breeding system, gestational period, number of offspring at birth, power and presence of intercurrent diseases) related to the onset of the disease.We evaluated the hematologic profile, and hormone metabolite in 77 sheep. The clinical manifestation of disease was observed in the ante-partum in 100% of animals, these 66.2% were discharged from clinic and 33.8% died. At birth multiple pregnancy was found in 57.1% of cases, while 42.9% had only one fetus. Most of these animals were kept in intensive farming systems corresponding to 61.0% and body condition were observed between four and five (49.3%). On clinical examination the main clinical signs were anorexia, weakness, dehydration, mucous congestion, depression, attitude ulcers, swelling of limbs and ruminal stasis. The clinical course ranged from five to 14 days in animals that died or were discharged from the clinic, respectively. In hematological profile showed a picture of leukocytosis, neutrophilia, lymphopenia and eosinopenia. Found hyperglycemia (46.9%), normoglycemia (39.4%) and hypoglycemia (13.6%). There was an increase in plasma glucose concentrations (x = 94.5), albumin (x = 3.02), urea (x = 59.8), creatinine (x = 2.3), ß-hidroxubutirato (x = 0 , 9), fructosamine (x = 206.4), lactate (x = 47.6), cortisol (x = 76.1) and non-esterified fatty acid (x = 1.00) in sheep affected. Analyzing the behavior between groups of animals that received high clinic and who died indicators for lymphocytes, cortisol, urea, aspartate aminotransferase and creatinine kinase was observed that significant differences existed (P <0.05), where the animals came the death had higher values.The research on ketone dipstick positivity was observed in urine 66.2% and for the Rothera test was 79.2%. This study confirms that pregnancy toxemia is a metabolic disorder and hormonal causes serious economic losses in sheep production, caused by the mortality of sheep and lambs.
