The term biotechnology is made from two words: bio and technology. The bio in biotechnology means "life" and refers to microbes and other living cells including animal and plant cells. The technology comprises the growth of living cells in vats (fermentors or bioreactors) containing nutrients and oxygen (if needed) at the specified conditions, and processing of biological materials produced by the cells through process integration and optimization at top efficiency for achieving commercialization. While there have been many practical applications for bio technology and humans, there has also been extensive research in bio technology and animals. Veterinary Biochemistry and 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.
