Índices produtivos e perfil metabólico de ovelhas Santa Inês no pós-parto no nordeste do Pará

This study reports production indexes, hematological values and plasmatic and serum biochemical values of primiparous and pluriparous Santa Inês sheep during postpartum, with controlled feeding, raised in Igarapé-açu, Pará.Twenty sheep were assigned into two groups: primiparous and pluriparous.Measurements were conducted at postpartum in predetermined times during lactation.Famacha, body and weight scores were considered as production indexes.Metabolic values of total blood (globular volume and hemoglobin); serum (total protein, albumin, globulin, calcium, phosphorus and magnesium) and plasma (glucose, urea and beta-hydroxybutyrate) were analyzed.Results from body scores, globular volume, hemoglobin, serum albumin and plasma urea indicated the need for minor adjustments regarding nutrients in the feed once being associated to forage promote slightly reduction of metabolic indicators.Variations in glycemia were physiological and demanded no use of the body reserved enough to promote the increase of the concentration of ketone bodies in the bloodstream.Results of Ca and P indicated physiological variations in the delivery and lactation demonstrating no sharp decline.These results, when combined, point out the need of a major protein adjustment in the diet.Metabolic indicators showed stress in the lactation of primiparous and pluriparous sheep; therefore nutritional adjustment should be conducted for both groups at the beginning, peak and end of lactation.
