Management of calves with neonatal diarrhoea:Animal Health Ireland Calf Care Technical Working Group (TWG)

摘要

Calf diarrhoea is still the most common health issue in young calves, causing significant financial losses to the Irish cattle industry every year and, equally importantly, a great deal of stress and increased workload for farmers. Under intensive farming conditions it may not always be possible to prevent calf diarrhoea by optimising husbandry and management. The most frequently identified infectious agents in young calves with diarrhoea are Rotaviruses and Cryptosporidia. These infections result in villous atrophy and crypt cell hyperplasia, leading to mixed malabsorptive and secretory diarrhoea. Enterotoxic E. coli are of minor importance and can only cause diarrhoea in calves up to five days of age.
