Abstract:
Weaning rabbits under the age of 3 months are most susceptible to coccidiosis, which is caused by the infection of 11 Eimeria species.However, no data is available about the susceptibility of rabbits under the age of 3 months.In this study, groups of rabbits at different ages (30 d, 50 d and 70 d) were infected with same dose of sporulated oocysts of Eimeria media or E.irresidua.Oocysts shed in feces during day 1 and day 5 after the infection were counted daily.The total number of oocysts production of 70 d old rabbits infected with E.media only was 3.7 ×107, obviously less than 30 d old rabbits (1.03 ×108) and 50 d rabbits (6.5 ×107).The same phenomenon was seen in rabbits infected with E.irresidua. At the same time, the clinical symptoms of the younger rabbits were obvious, reflecting depression, constipation and diarrhea.These results indicated that weaning rabbits at the age of 30 days are the most susceptible and thus provides clues to the control of coccidiosis in young rabbits.
