摘要

虽然缺铁性贫血在仔猪中得到了很好的认识,但其在小牛和羔羊中的诊断和治疗的重要性最近才得到强调。特别是,圈养的以全脂牛奶喂养的羔羊和小牛容易患亚临床缺铁性贫血,调查显示患病率从20%到50%以上。许多研究表明,这两个物种的主要临床症状是每日活重增加减少;一些还显示出健康问题,如犊牛肺炎和腹泻风险增加,羔羊皱胃胀气风险增加。铁补充试验一致导致断奶前更高的生长率和改善的血液学值。在英国,没有批准用于犊牛或羔羊的注射铁制剂,但批准用于猪的制剂可以在标签外使用。

Iron-deficiency anaemia in calves and lambs
While iron-deficiency anaemia is well recognised in piglets, the importance of its diagnosis and treatment in calves and lambs has been highlighted more recently. In particular, housed lambs and calves fed on whole milk are prone to subclinical iron deficiency anaemia, with surveys showing prevalence figures from 20% to more than 50%. Many studies show reduced daily liveweight gain as a main clinical sign in both species; some also show health issues such as increased risk of pneumonia and diarrhoea in calves and an increase in abomasal bloat risk in lambs. Iron supplementation trials consistently led to higher growth rates pre-weaning and to improved haematological values. In the UK, there are no injectable iron preparations licensed for calves or lambs, but preparations licensed for pigs can be used off label.
