Variations of plasma volume (PV) and variations of triglyceride, cholesterol, total lipid, beta-lipoprotein and phospholipid concentrations in the blood plasma were investigated in trials with ten sows, crossbreds of the White Thoroughbred and Landrace breeds, at the age of 2-3 years, kept on a defined diet; the trials were performed before the sows became pregnant and during their pregnancy (days 1-40, 41-60, 61-80, 81-100 and 101-120). The PV in nonpregnant sows is 9.8 +/- 0.33 1. Following a decrease to the values of 7.8 +/- 0.33 l (p less than 0.01) in the first 40 days of pregnancy the plasma volume increases in the successive periods and it makes 15.4 +/- 0.19 l at the end of pregnancy (p less than 0.001). Total lipaemia decreases during pregnancy from 2.80 +/- 0.054 in nonpregnant sows to 2.49 +/- 0.245 g per 1 in sows at the end of pregnancy. Cholesterol concentrations in the blood plasma also decrease from 2.48 +/- 0.53 in nonpregnant ones to 1.88 +/- 0.173 mmol per 1 (p less than 0.001) in sows at the end of pregnancy, beta-lipoprotein concentrations from 3.95 +/- 1.134 in nonpregnant ones to 3.47 +/- 0.199 g per l in sows on days of pregnancy 81-100 (p less than 0.05), phospholipid concentrations in the first 60 days of pregnancy from 1.62 +/- 0.079 before insemination to 1.29 +/- 0.05 mmol per l in sows of 41-60 day pregnancy.(ABSTRACT TRUNCATED AT 250 WORDS)
在对10头2至3岁的白色纯种与长白猪杂交母猪进行的试验中，研究了血浆量（PV）的变化以及血浆中甘油三酯、胆固醇、总脂质、β-脂蛋白和磷脂浓度的变化。这些母猪食用特定饮食，试验在母猪怀孕前及怀孕期（第1至40天、41至60天、61至80天、81至100天和101至120天）进行。未怀孕母猪的血浆量为9.8±0.33升。怀孕的前40天血浆量降至7.8±0.33升（p<0.01），随后各阶段血浆量增加，怀孕末期达到15.4±0.19升（p<0.001）。孕期总脂血症从未怀孕母猪的2.80±0.054降至怀孕末期母猪的2.49±0.245克/升。血浆胆固醇浓度也从未怀孕母猪的2.48±0.53降至怀孕末期母猪的1.88±0.173毫摩尔/升（p<0.001），β-脂蛋白浓度从未怀孕母猪的3.95±1.134降至怀孕81至100天母猪的3.47±0.199克/升（p<0.05），怀孕前60天磷脂浓度从输精前的1.62±0.079降至怀孕41至60天母猪的1.29±0.05毫摩尔/升。（摘要截于250字）
