This book describes the biological basis of reproduction in poultry and places this information in the context of poultry production. The author has collated and integrated recent information from a variety of sources in order to highlight the principles of the reproductive biology of poultry. This is achieved through a well-illustrated and tabulated text which emphasizes integration rather than comprehensive literature citations. The book begins by considering the egg, proceeds to a brief description of embryonic and chick development as they relate to poultry production, and describes the physiological processes that lead to formation of the fertile egg. It concludes with a discussion of the relationship between measurements of reproductive success that are commonly used in the poultry industry and their ability to reflect the physiological processes that contribute to successful reproduction. The book is aimed at advanced undergraduates or graduate students studying animal reproduction or agriculture, as well as scientists working in the poultry industry.

In the past half century great progress has been made in the reproductive management of farm animals, both mammals and birds. This book aims to review developments and indicate which reproductive technologies can be used commercially or in research. It begins by discussing artificial insemination and how this has recently been refined in semen sexing technology. Embryo transfer, in vitro embryo production technology and the control of oestrus and ovulation are then reviewed. Subsequent chapters consider the control of postpartum ovarian activity, seasonal breeding, multiple births and litter size, pregnancy testing, parturition, and the onset of puberty. The author then describes more recent developments in cloning and the production of transgenic animals, before a final chapter on suppressing reproductive activity.

Current Advances in Selenium Research and Applications

Selenium (Se) is an essential dietary trace element participating in the regulation of various physiological functions in both animals and humans through its incorporation into selenoproteins as the amino acid selenocysteine. Among many minerals Se has a special place being the most controversial trace element with a narrow gap between essentiality and toxicity. Indeed there are important environmental issues considering selenium as a pollutant from the one hand and global selenium deficiency on the other. In fact, Se deficiency is considered as a risk factor for the development of various diseases in human and animals. Decreased Se availability from soils as a result of low soil pH and usage of synthetic fertilizers is the major concern in European countries causing inadequate Se levels in food and feeds. Furthermore, it seems likely that sodium selenite used for the last 30 years as a feed supplement is not an optimal form of Se and the usage of organic selenium in animal diets could help to maintain optimal Se status as well as high immunocompetence, productive and reproductive performance.The aim of the present volume is to provide updated information on several important Se-related subjects, including Se status in Europe and ways of its improvement, advances in Se analysis and speciation in biological material, roles of selenium in poultry, pig and ruminant nutrition. Production of functional Se-enriched food, the relationship between selenium and mycotoxins, polyunsaturated fatty acids as well as reoviruses are also addressed. This collection of articles will provide nutritionists, veterinarians, human doctors, researchers and any other readers with new insights into the exciting world of the goddess of the moon - SELENIUM.

Continued genetic development of pigs and poultry has been the foundation of profitable production within a competitive market. However, the challenges of these production increases have undoubtedly taken their toll on reproductive function in all breeding livestock, with the incidence of infertility increasing at an alarming rate. For example, it has recently been estimated that over 40% of sows are culled due to fertility problems, compared to just 12% with feet and leg issues.This edited collection of papers is taken from a series of seminars, devoted to bringing together some of the world's leading authorities in the field of pig and poultry reproduction. The fundamental aim being to re-examine the current trends in productivity in the pig and poultry industries, and to identify nutritional means to improve fertility. It considers the effects of essential nutrients in optimising productivity, and discusses innovative applications of nutrition that will help to enhance fertility. The success of such innovations within entrepreneurial integrated systems is also covered, together with the importance of producing a quality chick and piglet at birth/hatching. Finally, the role of management and the need for least cost production is discussed. Nutritional Approaches to Arresting the decline in Fertility of Pigs and Poultry is aimed at nutritionists and animal producers as well as students and researchers studying animal and applied biological sciences.

Animal Signaling and Function

An Integrative Approach

Page: 272

The diversity of animal signals has been widely documented, and the generality of animal signals also tantalizingly suggests that there are common mechanisms that have selected for their origin. However, while much progress has been made on some fronts, we still lack a general theory about why the diversity of signaling structures exist. Our compilation will directly address this gap by focusing on an exciting new arena of sexual selection, namely using functional approaches to understand signaling. This approach is rooted in the idea that many signals are designed to transmit important functional imformation that is both important for issues of male quality (and hence male competition), and female choice. The increasing use of technology in sexual selection studies has enabled researchers to test whether signaling is either constrained by, or accurately transmits information about functional capacities. Further, in animals that fight vigorously, functional capacities such as endurance or strength may make the difference between winning and losing. This volume brings together a diverse collection of researchers who are actively investigating how function and signaling are related. These researchers use both a variety of methods and taxa to study animal signaling, and we believe that this integrative view is important to open up fresh vistas for why animal signals have evolved.
