Daftar Isi:
- Chickens are a poultry which produce the biggest meat in Indonesia. One of the obstacles in the farm of chicken is coccidiosis. This disease causes death on the population of chicken which makes high economic loss for farmers. Coccidiosis is a disease due to protozoa genus Eimeria. This research has a purpose to see the change of anatomy�s pathology microscopically of the caecum in chicken infected by Eimeria tenella. Five layer chickens were used for producing or multiplying oocyst. For the research 12 broiler DOC (Day Old Chick) were preserved until 18 days of age. The chickens were devided into 4 groups. Each group consisted of 3 chickens. Control group (without infection), group 2 (infected with 5000 oocyst), group 3 (infected with 10.000 oocyst) and group 4 (infected with 15.000 oocyst). On the 4�� day post infection, the bloody diarhea on the faeces was observed. Chickens were observed on the 5�� day post infection to get the caecum and were made histopathology preparation with HE stain to find the sexual or asexual stadium on epitelial of caecum. Pathologicals changes of caecum were analyzed descriptively. The result showed that presence koksidia breeding stage was visible, characterized by the macrogamets, microgamets, zygot, inflammation cell, erotion of epithelial cell in mukosa, and bleeding. There were raising destroyed tissues in higher infections. Can be conclude that higher dose of infection makes higher pathologycal changes including blooding, erosion of epithel and many stages of coccidia can be found. This observation should be done by separating stable with other observation�s groups to avoid oocysts�s contamination.
