Under the experimental conditions of a clinic, the dynamics of vitamin E was studied in the blood serum of 57 piglets from birth to the age of 90 days. The piglets came from eight litters delivered by sows, four of which were given a ration with an addition of vitamin E (tocopherol acetate -- 100 i. u. per kg of feed) and selenium (0.1 ppm Se as Na2SeO3) during gravidity, and another four were given these supplements only during lactation. In the first group the piglets showed a high level of vitamin E immediately after birth, before the first sucking (4.048 mumol .1-1), which increased to the maximum average level at the age of 10 days (24.127 mumol .1-1). Then followed a marked decrease down to 1.679 mumol .1-1, recorded after weaning. In comparison with this, after the supplementation of the sow feed ration during lactation, the highest value of vitamin E concentration was found on the 5th day of age (21.482 mumol .1-1). The level of vitamin E gradually decreased, but still after weaning the average value was quite high (2.783 mumol .1-1). The results suggest the possibilities of eliminating the critical values of low vitamin E concentration in the blood serum of pigs at birth and after weaning.
在临床实验条件下，对57头仔猪从出生到90日龄血清中维生素E的动态变化进行了研究。这些仔猪来自8窝母猪所产仔猪，其中4窝母猪在妊娠期给予添加了维生素E（醋酸生育酚——每千克饲料100国际单位）和硒（以亚硒酸钠形式添加0.1 ppm硒）的日粮，另外4窝母猪仅在哺乳期给予这些补充剂。第一组仔猪出生后、首次吮乳前维生素E水平较高（4.048 μmol·L⁻¹），在10日龄时升至最高平均水平（24.127 μmol·L⁻¹）。随后显著下降，断奶后降至1.679 μmol·L⁻¹。相比之下，在哺乳期母猪日粮补充后，维生素E浓度在5日龄时达到最高值（21.482 μmol·L⁻¹）。维生素E水平逐渐下降，但断奶后平均值仍相当高（2.783 μmol·L⁻¹）。结果表明有可能消除仔猪出生时和断奶后血清中维生素E浓度低的临界值。
