The Evolution of the Hemogram and Certain Biochemical Parameters from Blood and Milk of Sows During the first Week Post-Partum

摘要

Through hematological, biochemical and milk cell population investigationsperformed on blood and milk samples the developments in health and lactation in a group of 15 sowswith piglets was monitored. According to the obtained results the investigated physiologicalparameters were characterized by wide variations, with the mean falling within the reference valuesfor onset of lactation in sow and minor irregularities, with no pathological connotation. Erythrocyteindices showed significant oscillations, but with normal mean values for hematocrit (35.74%),associated with slight decreases in mean concentration of hemoglobin (8.20 g/dl), total number of redblood cells (5.78 T/l) and mean erythrocyte constants maintaining within the physiological limits. Theevolution of the leukocyte subpopulation showed normal values for total number of leukocytes (6.9 to14.9 G/l), except for two cases with leukocytosis, while revealing also an individual tendency towardsneutrophilia (40-41%), lymphocytosis (50-51 %) and eosinophilia (16%) and a general tendencytowards monocitosis (16-27%). Protein and energy index profile revealed normal proteins value (7.9g/dl), albumins (5.74 g/dl) and globulins (1.97 g/dl). Glicemia showed a decreasing trends around amean value of 81 9 mg/dl. GGT levels (31 to 49.5 IU) varied between physiological limits and alkalinephosphatase increased slightly around a mean of 215.2 IU. Blood ion levels showed normal values formagnesium (1.63 mg/dl), calcium (from 9.5 to 11.0 mg/dl) and phosphorus (6.78 to 9.14 mg/dl) forfive sows, other two showing hypercalcemia (37.2 to 39.2 mg/dl) associated with an increasedphosphorus level (23.21 to 23.83 mg/dl). Physico-chemical examination of milk has reported valuesnormal for the opening period of sow lactation regarding protein content (7.97%) and to a lesserdegree regarding solids (13.67%) and fat (8.18 %), the density having a value of 1.043 and a freezingpoint of 0.28 C. The milk cell population was characterized by a near majority proportion ofmacrophages (40.87%), with lymphocytes (31.0%) and PMN leukocytes (15.8%) an important ratiofalling to epithelial cells (12.33%).
