Haematological and biochemical parameters during pregnancy and lactation in sows

The aim of this research was to describe changes in serum concentrations of some micronutrients, and haematological parameters during pregnancy and lactation of sows. Data presented here were obtained by using blood samples from healthy, conventionally managed sows from a breeding herd. The samples were taken at three different points in the physiological production process: I. from the 30th to 35th day following artificial insemination ; II. from the 81st to the 87th day of pregnancy ; III. from the 12th to the 20th day of lactation. Erythrocyte count, haematocrit, MCV, leukocyte count and copper concentration decreased during pregnancy (P<0.05), while haemoglobin concentration decreased during both pregnancy and lactation (P<0.05). MCH increased at high pregnancy and decreased during lactation. Serum ALT activity, sodium concentration and inorganic phosphorus concentration decreased towards the end of pregnancy and lactation. Concentration of glucose increased during lactation. During pregnancy, zinc concentration increased. Results from this research could help to improve interpretation of laboratory data of sows during pregnancy and lactation.
