Preface
It is my pleasure to present a new book that integrates a continuing series on Veterinary
Medicine. Titled “Insights from Veterinary Medicine”, this book presents original research
results and reviews flashing several distinctive aspects of the Veterinary Medicine Sciences,
in which the knowledge has continuously increased over the past decades.
Veterinary and Human Medicine have been developed in close association, in part as a re‐
flection of the intertwined relationship found between animals and humans since the estab‐
lishment of first civilizations. Human and animals share common mechanisms of disease,
thus serving as spontaneous models for the study of particular disorders, such as tumors
and cardiac diseases. Furthermore, concerns regarding the deleterious side-effects of con‐
taminants, in particular over the endocrine axis regulating different body functions and fer‐
tility, are on the table, as humans share the same environment with animals and are subject
to the same influences, but also because humans can be exposed through the food chain.
Some of these subjects are presented within the book chapters.
The Veterinary Sciences are often at the vanguard of research in human diseases and behind
improvements in human health. Several and distinctive reasons may be found for that asso‐
ciation, such as the epidemiological, since many human pathogens have their origins in ani‐
mal hosts, or the physiological, once animals used as models of disease allowed to elucidate
the underlying mechanisms of many diseases. In addition, animals are a major contribution
to human welfare: the quality of the animal life with regards to both health and welfare also
contributes to the quality of human life, and food-animal health and safety are safeguards
against the disruption of the food chain. These topics are also brought to you in some of the
chapters of this book.
Advances in tests and procedures made possible through research changed the animal
world and both pets and farm animals enjoy a better quality of life today. Accompanying its
tremendous development, the Veterinary Medicine also broadened its scope of action and
nowadays it encompasses much more than the veterinary medical practice. Similarly, a wide
field of knowledge has been covered in this book. Even so, it was our goal to provide you
with current advanced resources in different veterinary science disciplines.
Veterinary research is also essential to the health and increased longevity of service and
companion animals and thereby reduces stress in both animals and owners.
This book includes different chapters on new developments covering a wide range of sub‐
jects from animal medicine and welfare to public health concerns and environmental endo‐
crine disruptors. The chapters are organized into four parts or sections, according to main
subjects. The initial section presents both educational and research chapters in major areas
VIII Preface
of bovine and pet internal medicine, ending with a paper highlighting important issues on
dairy cattle welfare in the tropics. The second section presents information pertaining to the
field of public health and discusses important zoonosis evolving on domestic and wild ani‐
mals worldwide. The third section highlights major aspects of hormones and hormone relat‐
ed diseases in mammals and aquatic organisms, including aspects associated to
environmental endocrine disruptors. Other materials related to the pharmacological and
toxicological effects of natural explants used as natural therapeutics in particular areas of the
globe are included in the final section.
I wish to thank all the authors for their contribution and efforts in improving the quality of
the book content, as well as the support by the members of InTech editorial and produc‐
tion team, for providing a stimulating and pleasant atmosphere during the book production.
To the reader, I hope you find this to be an interesting book well worth reading by any prac‐
titioner, graduating student or researcher searching for either highlights or an overview on
current topics in the Veterinary Science field.
