The book has been authored by 30 well experienced academia to match the syllabi in vogue prescribed by the Veterinary Council of India. In addition, we believe that it has also been useful to postgraduate students of Poultry Science and candidates appearing for JRF, SRF, ARS and NET examinations. Further, this book has also been prepared for the students of the Courses: Poultry Production & Business Management (PPBM), B. Tech, B.Sc Poultry Science and Poultry Science diploma.

The unique feather of this book is that at the end of each chapter there is a Question Bank with Answer key so as to help the students for self testing and prepare for the examinations.
