The concentrated Sulmet (Albon) for dogs (Rx only - is a yellow, pepperminty and sticky liquid) is to be given at 0.5 cc per 1 pound weight for first dose then 0.25 cc per 1 pound weight for 9 more days; with the youngest kits ( 4 weeks or less) I used a 1 cc dropper and gave 1/4 dropper per kit
The big gallon jug of Sulmet you buy at the feed store can be added to the water at 30cc per gallon for first run then 15 cc per gallon for consecutive runs and given for 10 to 14 days
Repeat treatment should be intiated 14 days after first treatment
When rabbits are on 6th or 7th day of treatment, move them into sanitized cages if at all possible, or remove them temporarily from their surroundings and sanitize by scrubbing away debris, then saturating with a strong ammonia solution. Allow the ammonia to dry and then rinse.
Soak nestboxes in a strong ammonia solution overnight, then allow to dry and soak again in water and rinse and dry
Clean watter bottles, nipple valves, resting matts, etc in ammonia as well
I dilute the cheap lemon scented ammonia cleaner at 1 part cleaner to 4 parts water
If you have had a severe outbreak of coccidiosis, you may need to do a third treatment and/ or prophylactiacally treat weanlings at weaning time.
Good luck. I find that too strong of a concentration of the sulmet causes loose stools, difficult birthings, and smaller litters in the does. But it is important to treat all of your rabbits at the same time, regardless of their gestational stage or age, due to the pernicious nature of coccidiosis. If you start to see loose stools, reduce the concentration by a small amount (about 5 cc per gallon reduction or 10% reduction in the oral bolus solution for canines) and feed more hay.
