SUMMARY:

The aim of the study was to evaluate the influence of hypocalcemia on the metabolism of primiparous Lacaune ewes in the peripartum. The study was carried out on a school farm in the municipality of Bento Gonçalves – RS, from July to August 2019. Nineteen Lacaune ewes kept in a semi-extensive system and receiving the same diet were used. On days -14, -7, -4 of the expected date of calving and on days 1, 4, 7 and 14 days after calving, blood collections, body condition score (BCS) assessment and body weight of the animals were performed. From blood metabolic markers, serum concentrations of total plasma proteins (TPP), albumin, aspartate amino transferase (AST), gamma glutamyl transferase (GGT), betahydroxybutyrate (BHBA), non-esterified fatty acids (NEFA), paraoxonase (PON1), calcium (Ca) and magnesium (Mg) were evaluated. Statistical analyzes were performed using the SAS program. Biochemical markers were influenced by the date of collection. BHBA had the lowest concentration on day -9 (p=0.031). NEFA showed the highest value on day 14 (1.07; p=0.014). In the mineral profile analysis, there was an interaction between category and pre-partum days, with a difference on day -14 for calcium (p=0.016) and magnesium (p=0.042). Magnesium had its lowest concentration detected on days 1 and 3 postpartum for the group of ewes without hypocalcemia. The peripartum of primiparous Lacaune ewes proved to be a time of change in blood metabolite markers.
