A : Encephalomalacia, disease of poultry is caused by the protozoan Eimeria
R : Encephalomalacia, causes bloody diarrhoea in poultry

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**: The assertion states that "Encephalomalacia, a disease of poultry, is caused by the protozoan Eimeria."
- **Analysis**: Encephalomalacia is actually a neurological condition in poultry, primarily caused by a deficiency of vitamin E, not by the protozoan Eimeria. Therefore, this assertion is incorrect.

2. **Understanding the Reason (R)**: The reason states that "Encephalomalacia causes bloody diarrhea in poultry."
- **Analysis**: Encephalomalacia does not cause bloody diarrhea. Instead, bloody diarrhea in poultry is typically associated with coccidiosis, which is caused by the protozoan Eimeria. Thus, this reason is also incorrect.

3. **Conclusion**: Since both the assertion and the reason are incorrect, we can conclude that:
- Assertion (A) is false.
- Reason (R) is false.

### Final Answer:
Both the assertion and the reason are incorrect.
