Animals as well as humans are facing protozoological problems in the daily life. It is necessary to control and understand the problem of protozoan and to understand their mode of transmission. This will help a lot to understand this subject. The animals, livestock, public health, food born and water born problems could be addressed by this manuscript. Moreover a direct approach could be achieved to overcome these metropolis problems, especially related to this tiny organisms

An utmost try has been made to full fill the modern requirements of the Procedures in Veterinary Entomology but still there is paucity of knowledge and literature regarding the understanding of insects anatomy, staining behavior, prevalence, feeding behaviors, location of suitable host, seasonal variations, vector role for various diseases of public health and zoonotic importance and periodicity. This manual will be helpful to the field Veterinarians, to the Graduates and Under Graduates, Veterinary Entomologists, Forensic Entomologists, to the Researchers and to the students of Veterinary Sciences. By any means, author does not claim perfectness and completeness of the manuscript. Any suggestion or recommendations for the improvement of the work will be highly obliged. Author, however, recommends the manual to be used as ready reference at teaching institutions, research institutions or at Diagnostic laboratories of Veterinary and Medical imporatnce public sector or in government sector.

Veterinary Epidemiology is an emerging field with its own unique demands that not only embraces the all disciplines of Veterinary Sciences but Economics, Statistics and Public Health also. Veterinary Epidemiology emerged not more than two decades ago but proved its worth and importance by gaining the place in the curriculum of all the Veterinary and Public Health institutions. It will be not exaggerating to say that the basic degree of DVM and Public Health is not complete without it. All the data collection, sampling size, Temporal and Spatial survey, disease Watch and Ward, Active and Passive Surveillances, Trans-boundary diseases, Veterinary Economics, Analysis of Data wither by computation or by simply or complex Statistics all is dealt by Veterinary Epidemiology. More over emerging Public Health needs and effective control of Zoonoses is not possible without understanding of Veterinary Epidemiology. Now it is gaining momentum in the Governmental Policy at small spectrum or at worldwide scenario. Different institutions are welcoming the students for higher studies in the discipline of Veterinary Epidemiology.

This is text book " on the welfare, management, diseases, rights and acts of laboratoryanimals and zoo animals" has been designed accordingto the latest syllabus of HEC for the Veterinary undergraduates pursuing for the degree of Doctor of Veterinary Medicine (DVM). This book will help the students to understand management practices and diseases of laboratory animals and animals in captivity. An utmost try has been made to full fill the modern requirements of the laboratory animals and captive animals. The most emerging field of Zoo Veterinarian will also get some benefits and the latest procedures adopted for rearing of laboratory animals, that are needed now a days in our institutions. Still there is paucity of knowledge and literature regarding the understanding of needs of experimental animals, prevalence of various diseases, feeding behaviours of exotic animals and special laboratory animals, building of specialized laboratory animal houses, seasonal variations, vector role for various diseases of public health and zoonotic importance.
