Studies were carried out to establish the severity of anemia in newborn pigs of sows under various raising technologies and some aspects of its drug prophylaxis. It was found that in the swine-breeding complexes that were investigated more than 50 per cent of the day-old piglets had the subclinical form of anemia (6 to 8 g% of hemoglobin content). With some raising technologies (tying the sows up to the feeders) about 17 per cent of the pigs were born with pathologic anemia (the hemoglobin content was below 6 g%). With the introduction of the new technologies the pigs were born with lower erythrocyte count of the blood. The decrease in the indices of the red blood picture (with some technologies there was also a drop of the serum iron) was seen in the sows too (better manifested when these were tied up to the feeders). The intamuscular injection of the fericin preparation of ferridextran, zinc, and vitamin B12 and B6 (doses of 4.0 g Fe3+) to the sows 21 days prior to farrowing neither hypochlorosis nor erythropenia of the newborns could be overcome. On the other hand, the i/m introduction in the thigh region of the preparation dextrofer-100 at the rate of 200 mg Fe3+ in a single injection to the newborns prevented anemia for 30 days. A second injection 7 days later of one more dose of the preparation did not bring about an essential improvement in the development of pigs. The single dose of 100 mg Fe per pig in the form of dextrofer-100 was not sufficient to produce an optimal antianemic effect.
开展了多项研究，以确定采用不同饲养技术的母猪所产新生仔猪贫血的严重程度及其药物预防的某些方面。结果发现，在所调查的养猪场中，超过50%的一日龄仔猪患有亚临床贫血（血红蛋白含量为6至8克%）。采用某些饲养技术（将母猪拴在食槽上）时，约17%的仔猪出生时患有病理性贫血（血红蛋白含量低于6克%）。随着新技术的引入，仔猪出生时血液中的红细胞计数较低。母猪的红细胞图像指标也出现下降（某些技术下血清铁也会下降）（当母猪被拴在食槽上时表现得更明显）。在分娩前21天给母猪肌肉注射铁葡聚糖、锌以及维生素B12和B6的铁制剂（剂量为4.0克Fe3+），无法克服新生仔猪的低氯血症和红细胞减少症。另一方面，给新生仔猪在大腿部位肌肉注射右旋糖酐铁-100制剂，单次注射剂量为200毫克Fe3+，可预防贫血30天。7天后再注射一剂该制剂，对仔猪的生长发育并没有带来实质性的改善。每头仔猪以右旋糖酐铁-100形式单次注射100毫克铁，不足以产生最佳的抗贫血效果。
