Reproduction is the backbone of animal-based food production. The reproductive systems of animals vary and are species-dependent. In this regard, all terrestrial animals perform internal fertilization, whereas aquatic animals perform different reproductive strategies such as internal fertilization without mating, external fertilization, viviparous, oviparous, and parthenogenesis. Today, reproductive biotechnology is an important part of the conservation and propagation of animals. This book addresses several hot topics in the field of reproduction of terrestrial and aquatic animals. Over five sections and eight chapters, this volume examines subjects such as cryopreservation, embryo transfer, avian reproduction, intraovarian gestation, and more.

Animal food production faces many challenges including shortage of high-quality feed ingredients, contribution of greenhouse gases and pollutants to the environment, development of antimicrobial resistance, food safety, and animal health and welfare. This examines these issues over three sections. The first section is the introduction. The second section provides insights into optimization of pasture utilization employing different supplements and feed additives to maximize beef cattle production, use of insect meal as a promising protein feed ingredient, and ruminal microbiome manipulation to improve ruminal fermentation efficiency. The third section discusses accurate estimation of enteric methane emission factors, reduction of enteric methane emissions by means of feeding management and antimethanogenic compounds, and different heavy metal pollution by poultry wastes and associated health hazards.

Despite significant worldwide progress in fighting rabies, a zoonotic viral disease, it remains an important public health concern, causing approximately 50,000 human cases per year. This book summarizes current knowledge regarding rabies, the prevalence and genetic diversity of the rabies virus, and modern approaches to rabies diagnosis, prevention, and treatment. It is a useful resource for scientists, doctors, and students.

Theriogenology, the field that studies animal reproductive health and disease, is a challenging field that shows a steady growth. It covers diverse aspects of reproduction in domestic and wild animals, including the assisted reproductive techniques, which have enormously enhanced the ability to rescue endangered species and provide a strong support to the high reproductive efficiency requested by livestock production. Reproductive success, as well as infertility, is the culmination of complex physiological and adaptive processes that guarantee, at the end, a species' ability to reproduce and its survival in a challenging and ever-changing environment. In this book, we present to you a collection of manuscripts exploring various aspects of the reproductive function of mammal and marine species. I hope you find this a useful book in your collection.

Under the title "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 reflection of the intertwined relationship found between animals and humans since the establishment of first civilizations. Humans 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 on the deleterious side-effects of contaminants, in particular over the endocrine axis regulating different body functions and fertility, are on the table, as animals may serve as sentinels for environmental quality. In addition, the quality of the animal life with regards to both health and welfare also contribute to the quality of human life, and food-animal health and safety are safeguards against the disruption of the food chain. The Veterinary Medicine field has broadened its scope of action, and nowadays it encompasses much more than the veterinary medical practice. Similarly, a wide field of knowledge was covered in this book. Even so, it was our goal to provide you with current advanced resources in different veterinary science disciplines.
