How to use Hydrafast:
Research has shown that continuing milk feeding during calf scour is very important to maintain calf strength and aid recovery. However, Hydrafast is much more effective than milk at rehydrating the calf and preventing metabolic acidosis, keeping the calf bright, so using Hydrafast alongside milk from the onset of scour is vital.

Ideal protocol:
At first signs of scour feed 2 litres of prepared Hydrafast solution twice daily and continue for at least 2 days.
Also continue milk feeding the calf or allow calf to suckle as normal if possible. Ongoing nutrition from milk is important for the calf’s recovery. If milk feeding, ensure a 3-hour gap between Hydrafast and milk feeding.
Administer Hydrafast orally, preferably using a feeding bottle with teat. Alternatively, bucket or tube feeding can be used.
Consider IV fluids if any of the following apply:

The calf can’t maintain sternal recumbency
The calf is extremely depressed with no suckle reflex
The calf still appears dehydrated after 48 hours of oral Hydrafast
Mixing instructions:

Mix the contents of one sachet in 2 litres of clean, fresh, warm water and mix thoroughly. Feed immediately.
