Evaluation of metabolic profile at different stages of peripartum of Santa Inês ewes in the Western Amazon

Abstract

This study aimed to evaluate the nutritional metabolic condition of Santa Ines ewes in antepartum and postpartum period, in order to avoid toxemia. Were used 50 Santa Ines ewes management under the same condition of handling and feeding, distributed into five groups, according to the gestation period: G1 - P-60 (60 days before partum), G2 - P-30 (30 to 21 days before partum), G3 - P0 (at partum to 4 days post partum), G4 - P+30 (30 days after partum) and G5 - P+60 (60 days after partum). The blood collection was conducted in the morning by venipuncture of the jugular in two vacuum tubes. The metabolites evaluated were: protein metabolism (total protein, albumin, globulin and urea), energy (glucose) and mineral (magnesium (Mg), calcium (Ca) and phosphorus (P)). To determine the differences between the means was applied the Tukey test at 5% probability. The serum concentrations of the protein metabolism (total protein, albumin and globulins), the mineral metabolism (calcium, phosphorus and magnesium) and the energy metabolism (glucose) according to the experimental phase showed significant differences (P<0.05), where the average β-hydroxybutyrate remained within the reference values for the breed. None of gestation stages presented metabolic deficiencies in protein and energy inputs for the diet and tested management phase. The mineral calcium showed low levels at the end of gestation and early lactation.
