摘要铁作为一种关键的微量元素,对动物的生长具有重大的意义,铁缺乏将会导致发育障碍、繁殖性能不佳、贫血和腹泻等多种不良影响。本研究以产前7 d 至产后21 d 的哺乳母猪(Sus scrofa domestica)为对象,探讨饲料中添加血能铁制剂对哺乳母猪生产性能、生理生化指标及仔猪相关指标的影响。结果显示,与空白对照组相比,以1 kg/t饲料添加剂量添加血能铁制剂后,连续饲喂28 d能够显著降低母猪助产率、提高断配率,改善母猪产程,增加仔猪初生窝重、仔猪平均体重、断奶窝重,降低仔猪腹泻率、畸形率、死胎率,从而提高母猪生产性能和仔猪生长性能;同时血能铁制剂可以提高第7天哺乳仔猪血清铁和总铁结合力,起到预防仔猪贫血的作用。本研究为兽医临床应用血能铁制剂提高母猪生产性能提供参考和依据。
Abstract：As a key element of trace elements, iron is of great significance to the growth of animals, and iron deficiency will lead to a variety of negative effects such as developmental disorders, poor reproductive performance, anemia and diarrhea. In this study, lactating sows (Sus scrofa domestica) from 7 d before farrowing to 21 d after farrowing were taken as the research object to investigate the effect of Iron preparations for blood added to feed on the production performance, physiological and biochemical indexes of lactating sows and piglet-related indicators. The results showed that compared with the blank control group, continuous feeding for 28 d after adding Iron preparations for blood at a dose of 1 kg/t of feed could effectively reduce the farrowing rate of sows, increase the mating rate, improve the labor process of sows, increase the litter weight of piglets, the average weight of piglets, the weight of the weaning litter, reduce the diarrhea rate, malformation rate and stillbirth rate of piglets, thereby improving the production performance of sows and growth performance of piglets. This study provides a reference and basis for the clinical application of Iron preparations for blood in veterinary medicine to improve the production performance of sows.
