Animal biotechnology includes any use of science or technology to alter the characteristics of a particular breed or animal. Genetic engineering is the manipulation of genetic material, that is DNA and RNA with the objective of bringing about desired change or innovation. In the present book, effort have made to incorporate the information on animal biotechnology, animal cell and tissue culture, biotechnology and animal cloning in genetic engineering. The book is intended primarily for undergraduate and postgraduate in animal biotechnology, biotechnology, zoology and animal science, whereas it can be used as reference for researchers and post-doctoral students, teachers and instructors. Contents: Preface. 1. Animal biotechnology. 2. Transgenic animals. 3. Animal cell biotechnology. 4. Animal cell and tissue culture. 5. Biotechnology and animals nutrition. 6. Genetic engineering. 7. Genetics analysis. 8. Cloning in genetic engineering. Bibliography. Index.
