Calf Scour

Calf scours, also known as calf diarrhoea, is a common and potentially deadly condition affecting young calves. In this blog, we will explore the causes, symptoms, and management strategies for calf scours.

Calf scours can be caused by various infectious agents, including bacteria, viruses, and parasites. Common pathogens involved in the development of scours include:

  1. Rotavirus and Coronavirus: These viruses are major contributors to calf scours, causing inflammation in the small intestine.
  2. Cryptosporidium Parvum: A protozoan parasite that can lead to diarrhoea and dehydration in calves.
  3. E Coli: Certain strains of E. coli can produce toxins leading to severe diarrhoea in calves.
  4. Salmonella: A bacteria can cause a range of gastrointestinal symptoms in calves, including diarrhoea.
  5. Coccidia: These are protozoan parasites that can damage the lining of the intestine, leading to diarrhoea.
  6. Poor Colostrum Quality: Inadequate intake of high-quality colostrum, which contains essential antibodies, can make calves more susceptible to infections.

Identifying the symptoms of calf scours early is crucial for effective intervention. Common signs include:

  1. Diarrhoea: The most apparent symptom, diarrhoea varying in colour and consistency often yellowish/watery.
  2. Dehydration: Calves with scours may become dehydrated rapidly due to fluid loss through diarrhoea.
  3. Appearance: Affected calves may appear weak, depressed, and unwilling to stand.
  4. Loss of Appetite: Calves may exhibit a reduced interest in eating or drinking.
  5. Sunken Eyes: Dehydration can result in sunken eyes, which is a clear sign of fluid imbalance.

Management and Treatment:

  1. Colostrum Management: Ensure that calves receive high-quality colostrum (>25% Brix Value) within the first few hours of life to boost their immune system. If colostrum value is not reached use SCCL Colostrum to top up your value.
  2. Electrolytes: Affected calves treat with Hydrafast oral rehydration or Bi Pill (Bicarbonate Bolus).
  3. Hygiene: Implement a good hygiene protocol to minimize the risk of contamination and spread of pathogens.
  4. Isolation: Identify and isolate affected calves to prevent the spread of infectious agents to healthy ones.
  5. Fluid Therapy: Administer electrolyte solutions to reduce dehydration and restore electrolyte balance.

To conclude, early symptom recognition is crucial, including diarrhoea, dehydration, and weakness. Effective management involves providing quality colostrum, electrolyte solutions for dehydration, good hygiene practices and isolating affected calves.
