[Changes in blood levels of glucose and lactic acid in pregnant sows and fetuses and in sows and piglets 10 days after parturition].
In three series of experiments the variations of lactic acid and glucose concentrations were investigated in pregnant sows, crossbreds of the Large White and Landrace breeds, and in their foetuses on the 104th and 113th day of pregnancy, then in farrowing sows of the same breed and their piglets at delivery (birth) and till the 10th day after birth. In nonpregnant sows the value of lactacidaemia is 1.60 +/- 0.08 mmol per 1. In the first twenty days of pregnancy it increases to 2.50 +/- 0.95 mmol per 1 (p less than 0.05). In the following days of pregnancy until the 81st to 100th day the value ranges from 1.5 to 1.7 mmol per 1. In the last twenty days of pregnancy it increases slightly to 2.10 +/- 0.25 mmol per 1. On the 104th and 113th day the values of lactacidaemia in foetuses in vena and arteria umbilicalis make 7.40 +/- 0.41 and 6.80 +/- 0.37, or 8.50 +/- 0.43 and 8.16 +/- 0.21 mmol per 1, respectively. Glucosaemia values are decreasing in pregnant sows in the first forty days, in the following period of pregnancy they are increasing and on the 101st to 120th day of pregnancy they make 5.39 +/- 0.26 mmol per 1. The foetus to dam ratio lactic acid concentrations is 2.3 and 2.1, respectively, on the 104th and 113th days. Lactacidaemia is highest in farrowing sows (3.15 +/- 0.19 mmol per 1), then there is a statistically significant decrease in the value of this characteristic, and on the day after delivery it makes 2.38 +/- 0.66 mmol per 1.(ABSTRACT TRUNCATED AT 250 WORDS)
