Preface The world of books is so large; however, it is possible for everyone to discover interesting books. Since the

time I was a student preparing for ICAR PG entrance examination, I always felt the need of a clear and

concise book on animal science subjects. I decided to write a book that provides an easy and quick

approach for the students preparing various postgraduate veterinary entrance examinations & state PSC

veterinary officer examinations.

The objective of this book is to present a concise collection of important aspects of animal science,

which are frequently asked in All India ICAR-PG examination. Every chapter starts with fundamentals

covering the topic in a coherent manner. All multiple-choice questions are compiled after going through the

entire standard books for a particular subject. The effort has been made to enable students to cover the topic

in a short time. I believe this book would certainly benefit aspirants of ICAR-JRF, SRF, IVRI-PhD, State

PSC Veterinary Officer, Civil services, IFS, and Field veterinarians.

I know the importance of visual memory for which a number of flowcharts, tables, and diagrams are

included in ANIMAL SCIENCE REFRESHER FOR ICAR-PG ENTRANCE EXAMINATION.
