Niveis de calcio serico em porcas gestantes e em trabalho de parto

The aim of this work is to establish the serum levels of total, ionic and albumin calcium for gestation and lactating sows and to study the correlation between these data and reproductive indices. Fifty sows were used. The blood was taken at 60 days on gestation sows and at the farrowing moment, from the front cava venipuncture. The total, ionic and albumin calcium estimated for gestation and in farrowing sows was 9.71±1.21 mg/dL and 10.09±2.17 mg/dL, 3.78±0.83 mg/dL and 3.28±0.65 mg/dL, 2.8±0.4 g/dL and 2.9±0.5 g/dL, respectively. Hypocalcemia was observed in 16% of in farrowing labor sows. The average time for farrowing was 164 minutes. The average interval of piglets’ birth was 16 minutes and 0.88 was the observed stillbirth number. The correlation between the low levels of calcium and the reproductive indices were not observed. Statistic differences were not observed between the total, ionic and albumin levels of calcium for gestation and in farrowing labor sows
