[ JMHO] -If you raise in cages with wire floors, first clean the cages, then - treat the doe between litters, with garlic or onion family plants , or panacur, and ponazuril, and then [the day after treatment period] use a brush with a strong ammonia solution to clean, and sanitise the cages [and adjacent cages] , and let it dry before returning rabbits to the cages.
garlic-for-coccidiosis-and-maybe-e-c-protozoan-parasites-t20890.html [see this thread for garlic info] I prefer the natural treatment but have corid and have used it a lot in the past for intestinal coccidiosis [not hepatic coccidiosis]., there is some concern about using it on pregnant does, but I personally have never seen a problem. [just know, Corid is a coccidiostat not a coccidiocide , it is designed to "cripple" cocci, not kill all of them, to give the animal time to develop an immunity ], so-- with that in mind, I would suggest a coccidiocide, [ not Corid] for this problem. -- [JMHO]

Diagnosis
Coccidiosis is very difficult to diagnose. It can be done by fecal flotation, by identifying the oocysts in the feces, or under the microscope by counting the coccidia per gram of feces. Coccidian oocytes may be difficult to differentiate from the rabbit-specific yeast, Cyniclomyces guttulatus.
If tests confirm the presence of E. intestinalis, E. flavescens, E. irresidua and E. piriformis, treatment should start immediately
Treatment
Treatment of hepatic coccidiosis is difficult and the disease may remain present for life. The anti-coccidiosis treatment is successful only for rabbits infected since 5 to 6 days. Even if the treatment is successful, mortality and diarrhea will continue during the next few days. Relapse is regularly observed after 1 or 2 weeks.
Robenidine hydrochloride is well tolerated by rabbits, but its regular preventive use over the last 20 years has raised resistance of e.g. E. media and E. magna toward this compound. Further drugs used to treat the parasite include:
Sulfonamide and trimethoprim antibiotics have proven efficacious in the treatment of coccidiosis. They should only be used to cure the disease, never as a preventive measure. The most effective drug is sulphadimethoxine (0.5 to 0.7 g / liter water). It is the well tolerated by pregnant and nursing does. Other sulpha drugs include:
· sulphaquinoxaline in drinking water: 1 g/litre;
· sulphadimerazine in drinking water: 2 g/litre.
· Salinomycine (Bio-Cox®);
· Diclazuril (Clinicox®);
· Toltrazuril (Baycox®), 2.5 to 5 mg/kg (higher doses cause anorexia and decrease in size of fecal droppings), twice, repeat after 5 days.
Treatment is best administrated to all the rabbits during a minimum of 5 days. The treatment should be repeated after 5 days.
Treatment of the environment is important (e.g. 10% ammonia). Water crocks and feed hoppers should be disinfected and remain free of rabbit feces. When treating a carpet, vacuum first in order to further penetration of the anticoccidial product. During treatment of the environment, rabbits should be kept in another part of the home to avoid the danger of contact with the products and possible intoxication.
Prevention
Branches and leaves rich in tannin (willow, hazelnut, oak, ash, fruit trees, eventually pines) are excellent in preventing coccidiosis. Before a rabbit is given a twig to chew, it is important to check that it’s picked from a tree that is not toxic to rabbits. Furthermore, the tree must not have been exposed to chemicals or pollution from busy roads.
JMHO-- this article makes this sound fairly hopeless, but-- it is not-- once you know you have an infection, it is easy to treat with Garlic, Garlic tops, Onion tops, or Garlic chives-[and garlic also helps control secondary infections] - and there is evidence to show that garlic is not harmful to rabbits in moderate doses-- The link to the article
garlic-for-coccidiosis-and-maybe-e-c-protozoan-parasites-t20890.html above shows convincing evedence [other then my experience] that it works.
