Calfhood diseases have a major impact on the economic viability of cattle operations. The second of this three part review series considers the management of diarrhoeic diseases in pre-weaned calves. In neonatal calf diarrhoea, oral rehydration therapy is the single most important therapeutic measure to be carried out by the farmer and is usually successful if instigated immediately after diarrhoea has developed. Continued feeding of milk or milk replacer to diarrhoeic calves is important, to prevent malnourishment and weight loss in affected calves. Indiscriminative antibiotic treatment of uncomplicated diarrhoea is discouraged, whereas systemically ill calves can benefit from systemic antibiotic treatment for the prevention of septicaemia or concurrent diseases. Ancillary treatments and specific preventive measures are discussed. Eimeriosis has a high economic impact on the farming industries due to direct cost of treatment and calf losses, but especially due to decreased performance of clinically as well as sub-clinically affected animals. Emphasis lies on prophylactic or metaphylactic treatment, since the degree of damage to the intestinal mucosa once diarrhoea has developed, makes therapeutic intervention unrewarding.
犊牛疾病对牛场的经济生存能力有重大影响。本系列文章共三篇，这是第二篇，主要讨论了未断奶犊牛腹泻性疾病的管理。在新生犊牛腹泻中，口服补液疗法是农民进行的最重要的单一治疗措施，如果在腹泻发生后立即开始，通常是有效的。继续给腹泻犊牛喂食牛奶或代乳料非常重要，以防止患病犊牛营养不良和体重减轻。不提倡对无并发症的腹泻进行无差别抗生素治疗，而全身性疾病的病犊可以从全身性抗生素治疗中获益，以预防败血症或并发疾病。本文还讨论了辅助治疗和特定预防措施。艾美耳球虫病由于治疗费用和犊牛损失，对养殖行业有很高的经济影响，但尤其由于临床和亚临床受影响动物的性能下降，造成的影响更大。重点在于预防性或治疗性治疗，因为一旦发生腹泻，对肠黏膜的损害程度使得治疗干预变得得不偿失。
