Heme is an efficient dietary iron supplement applied in humans and animals to prevent iron deficiency anemia (IDA). We have recently reported that the use of bovine hemoglobin as a dietary source of heme iron efficiently counteracts the development of IDA in young piglets, which is the common problem in pig industry. Here, we used maternal Polish Large White and terminal sire breed (L990) pigs differing in traits for meat production to evaluate the long-term effect of split supplementation with intramuscularly administered small amount of iron dextran and orally given hemoglobin on hematological indices, iron status, growth performance, slaughter traits, and meat quality at the end of fattening. Results of our study show that in pigs of both breeds split supplementation was effective in maintaining physiological values of RBC and blood plasma iron parameters as well as growth performance, carcass parameters, and meat quality traits. Our results prove the effectiveness of split iron supplementation of piglets in a far-reach perspective.
血红素是一种高效的膳食铁补充剂，应用于人类和动物，以预防缺铁性贫血（IDA）。我们最近报道，使用牛血红蛋白作为膳食血红素铁的来源，可以有效地抵抗仔猪 IDA 的发生，这是养猪业中常见的问题。在这里，我们使用母系波兰大白猪和终端父系品种（L990）猪，它们在肉质生产方面的特性不同，评估肌肉内给予小剂量的右旋糖酐铁和口服给予血红蛋白的分次补充对血液学指标、铁状态、生长性能、屠宰特性和育肥期末肉质的长期影响。我们研究的结果表明，在两种品种的猪中，分次补充都能有效地维持 RBC 和血浆铁参数以及生长性能、胴体参数和肉质特性的生理值。我们的结果从长远角度证明了仔猪分次补铁的有效性。
