A comprehensive review of all aspects of commercial production systems, this book provides an up-to-date look at all aspects of broiler breeder production and management, starting with specialized genetic programs as developed by the primary breeders and ending with two chapters on very practical, hands-on aspects of breeder management, including extensive coverage of health management, feeding systems, environmental control, lighting programs and all aspects of male and female reproduction. Recognizing the diversity of management systems worldwide, the authors have included breeders in both temperate and warm climates and also for controlled environment vs.curtain-sided housing systems. This unique publication is an essential reference for all professionals involved in broiler breeder production.

Covering a variety of essential topics relating to commercial poultry nutrition and production—including feeding systems and poultry diets—this complete reference is ideal for professionals in the poultry-feed industries, veterinarians, nutritionists, and farm managers. Detailed and accessible, the guide analyzes commercial poultry production at a worldwide level and outlines the importance it holds for maintaining essential food supplies. With ingredient evaluations and diet formulations, the study's compressive models for feeding programs target a wide range of commercially prominent poultry, including laying hens, broiler chickens, turkeys, ducks, geese, and game birds, among others.

Broiler breeder chickens are the parent stock used to produce broiler chickens raised for human consumption and have long been caught in a welfare dilemma. The immensely successful selection of fast-growing meat-type chickens over the last 80 years has created a remarkably efficient meat-producer and given us access to cheap chicken meat but has also created health problems for the animals. These problems especially affect the breeder generation, which must be raised with strict feed restriction to limit weight gain and thus maintain physical health and normal fertility. At the same time, however, feed restriction causes chronic hunger and feeding frustration with reduced animal welfare as a result. In the EU alone 60 million breeders are affected annually and although the problem is well-known within the industry, there is financial incentive to keep selecting for even higher growth potential in broilers, further increasing the problems for broiler breeders. Many strategies for reducing the impact of growth restriction on breeder welfare have been suggested and are usually aimed at somehow increasing the amount of feed given at feeding times. This can be done either through adding bulky fibers to the diet or by reducing feeding frequency. In this thesis, focus is on the latter as we explore the effects of intermittent fasting (IF) on the welfare of young broiler breeders as well as wild-type Red Junglefowl. Intermittent fasting, or “skip-a-day” feeding, is supposedly the most common feeding strategy for broiler breeders worldwide but is perceived as welfare-reducing and thus illegal in Sweden and several other European countries. In spite of this, the scientific knowledge of how this type of feeding affects chicken welfare is scarce. Assessing the overall effect of IF on breeder welfare is complicated by large variations in both physiological and behavioral parameters between feeding and fasting days, but it does appear that chicken welfare is improved at least on the feeding days of IF regimens. It also seems that some of the health benefits reported from mammalian studies of IF may apply to chickens as well, although behavioral indicators still point to welfare issues unless the level of feed restriction can be relaxed. In comparison with daily feed restriction, IF appears to increase the motivation for feed consumption but to reduce the motivation for appetitive behaviors such as foraging, which may explain why birds fed on this type of schedule are often reported as calmer.

The aim of this Special Issue is to publish high quality papers concerning poultry nutrition and the interrelations between nutrition, metabolism, microbiota and the health of poultry. Therefore, I invite submissions of recent findings, as original research or reviews, on poultry nutrition, including, but not limited to, the following areas: the effect of feeding on poultry meat end egg quality; nutrient requirements of poultry; the use of functional feed additives to improve gut health and immune status; microbiota; nutraceuticals; soybean meal replacers as alternative sources of protein for poultry; the effects of feeding poultry on environmental impacts; the use of feed/food by-products in poultry diet; and feed technology.

Egg Innovations and Strategies for Improvements examines the production of eggs from their development to human consumption. Chapters also address consumer acceptance, quality control, regulatory aspects, cost and risk analyses, and research trends. Eggs are a rich source of macro- and micronutrients which are consumed not only by themselves, but also within the matrix of food products, such as pastas, cakes, and pastries. A wholesome, versatile food with a balanced array of essential nutrients, eggs are a stable of the human diet. Emerging strategies entail improvements to the composition of eggs via fortification or biological enrichment of hen's feed with polyunsaturated fatty acids, antioxidants, vitamins, or minerals. Conversely, eggs can be a source of food-borne disease or pollutants that can have effects on not only human health, but also egg production and commercial viability. Written by an international team of experts, the book presents a unique overview of the biology and science of egg production, nutrient profiling, disease, and modes for increasing their production and quality. Designed for poultry and food scientists, technologists, microbiologists, and workers in public health and the food and egg industries, the book is valuable as an industrial reference and as a resource in academic libraries. - Focuses on the production and food science aspects of eggs - Includes a broad range of microbial contaminants, their risks, and prevention, as well as non-microbial contaminant risks - Presents analytical techniques for practical application

This book addresses the impacts of current and future reproductive technologies on our world food production and provides a significant contribution to the importance of research in the area of reproductive physiology that has never been compiled before. It would provide a unique opportunity to separate the impacts of how reproductive technologies have affected different species and their contributions to food production. Lastly, no publication has been compiled that demonstrates the relationship between developments in reproductive management tools and food production that may be used a reference for scientists in addressing future research areas. During the past 50 years assisted reproductive technologies have been developed and refined to increase the number and quality of offspring from genetically superior farm animal livestock species. Artificial insemination (AI), estrous synchronization and fixed-time AI, semen and embryo cryopreservation, multiple ovulation and embryo transfer (MOET), in vitro fertilization, sex determination of sperm or embryos, and nuclear transfer are technologies that are used to enhance the production efficiency of livestock species.

This classic reference for poultry nutrition has been updated for the first time since 1984. The chapter on general considerations concerning individual nutrients and water has been greatly expanded and includes, for the first time, equations for predicting the energy value of individual feed ingredients from their proximate composition. This volume includes the latest information on the nutrient requirements of meat- and egg-type chickens, incorporating data on brown-egg strains, turkeys, geese, ducks, pheasants, Japanese quail, and Bobwhite quail. This publication also contains new appendix tables that document in detail the scientific information used to derive the nutrient requirements appearing in the summary tables for each species of bird.

This book reviews the biological science and background to breeding meat poultry, specifically broiler, turkey and duck. These commercial birds have been changed by genetic selection to such an extent that they are substantially different from traditional breeds and laying hens. Covering science, management and husbandry systems, this book is an essential reference for researchers and students in animal science, as well as technical staff of breeding companies and poultry meat producers. Part of the Poultry Science Symposium Series.
