Abstract

Thirty six 25-day-old suckling rabbits and thirty six 29-day-old rabbits weaned since one day were orally vaccinated with one of the two doses (3.5 x 103 or 3.5 x 104 oocysts) of a precocious line of Eimeria magna. Only the groups vaccinated with the highest dose displayed a vaccine reaction, but without diarrhea or mortality. A vaccination totaly or incompletely protected against disease, assessed by daily growyh rate patterns, according to the dose given and reduced oocyst output 10 to 1000 times, measured between the 4th and the 10th day following the challenge inoculation.
