Start all calves which have scours on KRYPTADE. Early detection is important so observe the group carefully  to identify depressed calves before they scour. Dose according to label. Give 2 doses within 6 – 8 hours, and follow with 12 hourly until appetite returns. The two treatments close together 6 – 8 hours apart is important to halt the multiplication cascade of oocysts. Farmers find calves noticeably brighter at the end of the first day, with appetite returning for over 70% of calves at 24 hours.  However where high energy electrolytes are used to treat these calves, a further delay of 24 hours in return of appetite can be experienced.

Using high energy (also known as hypertonic) electrolytes calves with infectious scours during early recovery will delay the return of the calf’s appetite to milk. Normal levels of milk in these early recovery stages is associated with reduced appetite. So only offer a much lower volume of milk, but at more frequent intervals than normally offered.

Always care for the hospital mob after the healthy calves. Pay particular attention to scrubbing feeding buckets, keeping all water sources clean. Wash footwear to get rid of any contaminating scour material that may be transferred between healthy and hospital mobs. Especially wash footwear on leaving the hospital/sick group. You may not be able to kill oocysts but you can reduce the transference. Consider whether the drainage from where this cleaning is carried out, may be contaminating an area and possibly contributing to further problems. Other creatures may be also involved such as rats, and birds, so take extra steps to limit their access.

General  – Returning Calves to Milk

  • Offer milk gently to affected calves after 24 hours to test their appetite. Separate out the recovering calf into a feeding group where the volume can be managed carefully.
  • Those calves receiving milk in recovery must have reduced and controlled amounts of milk. Several small meals – 25% – 33% of normal volumes are recommended. This is aimed to keeping them drinking by avoiding discomfort.
  • There is also the risk of rebound scours from excessive intake with too much milk volume to a gut that is unable to handle the digestive processes (i.e we aim to avoid a nutritional scour).
  • This recovery period is particularly important in the 24 -36 hours after returning calves to milk which earlier had lost their appetite.

Overnight Management: Ad-lib electrolytes
For additional improvement to rehydration  it is recommended that an isotonic electrolyte e.g. ENERVADE or KRYPTADE is available ad lib (freely available) to all calves overnight, offering this 2-3 hours after feeding.

Also keep fresh water available at all times.
