This book briefly reviews the history of equine embryo transfer, covering in clinically practical terms the techniques, equipment, and management protocols currently in use. Embryo transfer has become a big business, especially for breeding racing stock (horses and camels), and is therefore a very important aspect of equine practice. Ed Squires and
In some countries, especially on the European continent, there still exists a remarkable veal market. This type of meat production seems, irrespective of any economic forecasts, to remain unchallenged so long as consumers expect that restaurants should offer courses like "r6ti de veaux", "vitello a la casa" or "Kalbsschnitzel". Producers, at least since about the past 1-/2 decades, have been aware of the beneficial effect of anabolic agents in veal production. This is possible due to the lack of endogenous sexual hormones during the juvenile or prepuberal status of these animals. A discussion about the benefit / risk - evaluation in connection with the use of anabolic agents in general was promoted in recent years by the public. This concern occurred concomitantly with the detection of illegally treated veal calves and the occurrence of diethylstilbestrol (DES) residues in canned food containing veal. The aim of this paper is to summarize the present status of residue data in edible tissues and excreta in order to allow the evaluation of the risk (given in the paper of Hoffmann within this program) and to consider reasonable monitoring measures. We have to face the fact that without an efficient control system the illegal treatment of calves can not be excluded. Therefore, this paper will not only consider different compounds and formulations, but will also deal with practised routes of administration.
This book offers a unique perspective on the invisible organ, a body part that has been visualized only recently. It guides the readers into the world of the microbial constituents that make humans the way they are. The vitamins they produce, the smell they generate, the signals they create, and the molecular guards they elaborate are some of the benefits they bestow on humans. After introducing the notion as to why microbes are an integral component in the development of humans, the book examines the genesis of the microbiome and describes how the resident bacteria work in partnership with the skin, digestive tract, sexual organs, mouth and lungs to execute vital physiological functions. It then discusses the diseases that are triggered by the disruption of the harmonious relationships amongst these diverse systems and provides microbial cures to ailments such as obesity and digestive complications. Finally, the book focuses on the future when the workings of the human microbes will be fully unravelled. Societal changes in health education, the establishment of the microbiome bank, the fight against hunger, space travel, designer traits and enhanced security are explained. Each chapter is accompanied by captivating illustrations and ends with a visual summary. Dr. Appanna has been researching for over 30 years on various aspects of microbial and human cellular systems. He is a professor of biochemistry and has also served as Department Chair and Dean of the Faculty at Laurentian University, Sudbury, Canada. The book is aimed at readers enrolled in medical, chiropractic, nursing, pharmacy, and health science programs. Practicing health-care professionals and continuing education learners will also find the content beneficial.
Although aquaculture as a biological production system has a long history, systematic and efficient breeding programs to improve economically important traits in the farmed species have rarely been utilized until recently, except for salmonid species. This means that the majority of aquaculture production (more than 90 %) is based on genetically unimproved stocks. In farm animals the situation is vastly different: practically no terrestrial farm production is based on genetically unimproved and undomesticated populations. This difference between aquaculture and livestock production is in spite of the fact that the basic elements of breeding theory are the same for fish and shellfish as for farm animals. One possible reason for the difference is the complexity of reproductive biology in aquatic species, and special consideration needs to be taken in the design of breeding plans for these species. Since 1971 AKVAFORSK, has continuously carried out large scale breeding research projects with salmonid species, and during the latest 15 years also with a number of fresh water and marine species. Results from this work and the results from other institutions around the world have brought forward considerable knowledge, which make the development of efficient breeding programs feasible. The genetic improvement obtained in selection programs for fish and shellfish is remarkable and much higher than what has been achieved in terrestrial farm animals.
This open access book identifies and discusses biodiversity’s contribution to physical, mental and spiritual health and wellbeing. Furthermore, the book identifies the implications of this relationship for nature conservation, public health, landscape architecture and urban planning – and considers the opportunities of nature-based solutions for climate change adaptation. This transdisciplinary book will attract a wide audience interested in biodiversity, ecology, resource management, public health, psychology, urban planning, and landscape architecture. The emphasis is on multiple human health benefits from biodiversity - in particular with respect to the increasing challenge of climate change. This makes the book unique to other books that focus either on biodiversity and physical health or natural environments and mental wellbeing. The book is written as a definitive ‘go-to’ book for those who are new to the field of biodiversity and health.
In this provocative book, Douglas Candland shows that as we begin to understand the way animals and non-speaking humans "think," we hold up a mirror of sorts to our own mental world, and gain profound insights into human nature. Weaving together diaries, contemporary newspaper accounts, and his own enlightening commentary, Candland brings to life a series of extraordinary stories. He begins with a look at past efforts to civilize feral children. We meet Victor, the Wild Boy of Aveyron, now famous as the subject of a Truffaut film; Kaspar Hauser, raised in a cell, civilized, and then assassinated; and the Wolf Girls of India, found early this century huddled among wolf pups in a forest den (they were originally believed to be ghosts by superstitious villagers, who nearly shot them as they were being captured). In each case, it was hoped that the study of these children would help clarify the age-old nature/nurture debate, but, as Candland shows, so much of the information "revealed" was really only a projection of beliefs previously held by the investigating scientists. Candland then turns to "clever animals." We learn how the investigation of "Clever Hans," the German horse who could calculate square roots, proved to be a first step in the direction of behaviorism (researchers found that Hans was being tipped off by the subtle and unwitting body language of his owner and other observers, who would bend almost imperceptibly at the waist with every hoof beat, and stand erect when the correct count was reached). And Candland discusses the many attempts to communicate with our closest neighbor, the apes. We read of Richard Lynch Garner's 1892 experiment living with chimpanzees in Gabon (he taught one to say the French word "feu"), and of Gua, raised by W.N. and L.A. Kellogg alongside their own son Donald, and of the latest successes of teaching sign language to such precocious apes as Sarah, Sherman, Austin, and Koko. Throughout, Candland illuminates the boldest and most intriguing efforts yet to extend our world to that of our fellow creatures. And he shows that, in the end, our effort to "make contact" is a reflection of the way in which we as a species create and order our universe. Humans have long shown a wish to connect with the silent minds around them. In assembling and interpreting the compelling tales in this book, Candland offers us a new understanding not only of the animal kingdom, but of the very nature of humanity, and our place in the great chain of being.
