Undergraduate Veterinary students assume Biochemistry to be a terror among all the subjects. The fear in this aspect is just because of their sudden exposure to a vast knowledge available in basic sciences, especially in Biochemistry. Inorder to overcome this nightmare, there was an urgent need to prepare a text book for Veterinary Sciences which put forth a brief description of Biochemistry, just enough to understand the other subjects required to complete the B.V.Sc. & A.H course. Hence this book Veterinary Biochemistry & Biotechnology is prepared keeping in view the immature minds of the students who just entered a professional course. No doubt that there are a number of books, available in the market embedding very many details of each and every aspect of Biochemistry, but this books gives only the basic information in the form of short notes in a very simple language. Understanding a glossary of terminnologies in English itself becomes a great task for the students. Had this course been designed in the individual's mother tongue then, more than half of the course would have been easier. Hence care has been taken to explain various topic in as simple language as possible. This book is prepared as per the syllabus prescribed by the Veterinary Council of India (V.C.I.) for the undergraduate B.V.Sc & A.H course. Biochemistry is prescribed to B.V.Sc & A.H students in both semesters of the first year, first semester of 4th year and a laboratory diagnostic course in the final year of study. Hence this book is divided into five different sections each grouping the topics under various courses. This book will serve as a handy material for the students as well as teachers, taking undergraduate and postgraduate courses in Veterinary sciences, Biological sciences, Genetics, Dental, Ayurvedic, Medical, Microbiology, Molecular Biology, Biotechnology and allied subjects. Students, who are appearing for various competitive exams, will find this book equally helpful.
