[Incidence and drug prevention of anemia in pigs in commercial swine breeding].
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.
