A partial chemical analysis of the blood serum of 293 suckling sows kept under typical large-scale production conditions were performed; the sows were divided into groups according to the individual days of puerperium. The calcium content was 8.23 +/- 1.53 mg per 100 ml of serum on the first day post partum, later on it increased slightly and it was highest on the 16th and 22nd day p. p., i.e. 10.22 +/- 1.80 and 9.77 +/- 1.51 mg per 100 ml, respectively. The increase was statistically significant on the 18th day p.p., and later on it was slightly statistically significant (P less than 0.1). Since the second week, the phosphorus content had dropped from the value of 4.10 +/- 0.63 mg per 100 ml on the 1st day p. p., and it mostly ranged below 4 mg per 100 ml, the average being 3.86 mg per 100 ml; the differences were not statistically significant (P greater than 0.1). The magnesium content raised from 1.75 +/- 0.43 mg per 100 ml on the first day p. p. to 2.50 +/- 0.56 mg per 100 ml on the fifth day; it remained higher for the whole puerperium. The differences were statistically highly to slightly significant (P less than 0.01 - P less than 0.01). The changes of the glucose content were irregular, within a relatively small range (86.52 +/- 16.79 to 115.92 +/- 26.70 mg per 100 ml of serum). The average value was 97.76 mg per 100 ml of serum and the differences obtained were statistically insignificant (P greater than 0.01). The vitamin A content amounted to 29.57 +/- 10.16 mcg per 100 ml on the first day; later on it increased up to 47.51 +/- 15.19 mcg per 100 ml on the 22nd day p.p. The increase since the 10th day and later on was statistically significant (P less than 0.05--P greater than 0.01).
对293头处于典型大规模生产条件下的哺乳母猪的血清进行了部分化学分析；这些母猪根据产后的天数进行分组。产后第一天，每100毫升血清中的钙含量为8.23±1.53毫克，之后略有增加，在产后第16天和第22天最高，分别为每100毫升10.22±1.80毫克和9.77±1.51毫克。产后第18天钙含量的增加具有统计学意义，之后略有统计学意义（P＜0.1）。从第二周开始，磷含量从产后第一天每100毫升4.10±0.63毫克的值下降，大部分时间低于每100毫升4毫克，平均值为每100毫升3.86毫克；差异无统计学意义（P＞0.1）。镁含量从产后第一天每100毫升1.75±0.43毫克增加到第五天的每100毫升2.50±0.56毫克；在整个产褥期都保持较高水平。差异具有高度到轻度统计学意义（P＜0.01 - P＜0.01）。葡萄糖含量变化不规则，范围相对较小（每100毫升血清86.52±16.79至115.92±26.70毫克）。平均值为每100毫升血清97.76毫克，所获得的差异无统计学意义（P＞0.01）。维生素A含量在第一天为每100毫升29.57±10.16微克；之后在产后第22天增加到每100毫升47.51±15.19微克。从第10天及之后的增加具有统计学意义（P＜0.05 - P＞0.01）。
