Syllabus, Civil Services & Forest Services Exams






 (With effect from 2011, the pattern of preliminary exam. has changed. There is no optional subject now. The change is notified as follows:


Changes in syllabus and pattern of the Preliminary Examination from
2011 in the scheme of Civil Services Examination

• As per the decision of Government of India, there shall be change in the syllabus and

Veterinary Zoology


         Animals suffer from a variety of diseases like humans. In animal husbandry, poultry, and pets it is important to know the symptoms of diseases so that timely treatment can be done.  Many animal diseases are described briefly under the following headings.

Viral diseases of animals

Bacterial diseases of animals

Protozoan diseases of animals

Helminthic diseases of animals
