ANS 134: Animal Nutrition Laboratory

2024. Julian Wiseman, ed. “Pig nutrition faces many challenges, including the need to meet the changing requirements of animals as they grow whilst minimizing environmentally damaging nutrient losses. Additionally, with growing crops for feed seen as a significant contributor to climate change, there is an emerging consensus that the sector must seek alternative, more sustainable feed sources which have a reduced impact on the environment. Advances in pig nutrition provides a comprehensive overview of the range of research addressing these challenges. The book addresses recent advances in understanding feed intake and feed formulation, focusing on advances in understanding pig nutritional requirements and ensuring feed safety. This collection also reviews the role of feed additives in optimizing pig nutrition, including amino acids, probiotics and prebiotics, as well as alternative growth promoters and exogenous enzymes.”

2012. John F. Patience,ed. This book is “a comprehensive treatise on the current state of our understanding of this topic which is so important to the pork industry. Each chapter is written by international authorities who understand both the science and application of their topic area. The book provides detailed insight into the many factors affecting feed efficiency, ranging from diet processing to herd health, from nutrition to physiology and from day-to-day barn management to the adoption of advanced technologies. The authors explain such practical aspects as the challenge of interpreting feed efficiency information obtained on farm or the role of liquid feeding. The authors also delve into more scientific topics such as amino acid or energy metabolism or animal physiology. This book is written for people who have a technical interest in pork production, including nutritionists, geneticists, farm management specialists, veterinarians, other academics and, of course, pork producers.”

2018 (2nd ed). R. Blair. This book “discusses the advices on nutrition and feeding practices that relate to the standards for certification of organic pigs and the production of organic pork; on how appropriate diet can be formulated and how feeding programmes can be integrated into an organic production system; and on international standards set for organic feeding of pigs. The book is intended for personnel, teachers, researchers, veterinarians, organic producers formulating diets and feeding programmes for pigs and regulatory authorities in several countries for addressing nutritional issues and relevant revisions of regulations in the future.”

2013. Francois Blachier et al, eds. “This book provides developmental data regarding piglets (with a focus on the gastrointestinal tract), data related to amino acid metabolism in pigs, data related to nutritional and physiological functions of amino acids in pigs, nutritional requirements for amino acids in pigs, signaling roles of amino acids, methodological aspects in amino acid research and the pig model for studying amino acid-related human diseases.”

2023 (2nd ed.). Lee Chiba, ed. “ Finding sustainable means of swine nutrition is important to both pork industry personnel and the environment alike. This reference comprehensively covers the most recent advancements in sustainability that results in more efficient diets, thus reducing both production costs and waste. Chapters include information on alternative feedstuffs, feed additives, bioavailabity of nutrients, and management of wastes and odors”

2021. Mick Bailey, et al. “The pig production sector faces many challenges, including the need to improve feed efficiency to reduce emissions from manure, finding alternative methods to prevent the onset of diseases affecting swine, as well as ensuring that the welfare of pigs is consistent with consumer and regulatory agencies' expectations. Understanding gut microbiomes as targets for improving gut health offers a comprehensive coverage on the wealth of research on the porcine gastrointestinal tract, its key role in pig health and nutrition, as well as its implications for improving feed efficiency and growth.”

2017. Jannes Doppenberg et al. “Fats and oils are more than 'just' energy sources for animal feeds. The fatty acids as part of triglycerides or in Fatty Acid products differ in chemical composition and physical characteristics. The omega-3 and specifically the LC-PUFA omega-3 fatty acids can be considered as functional nutrients. Via the feeding of different fats and differing fat additions body composition and animal products can be modified. The main use of fats and oils in the feed industry is however increasing the energy content of the feed economically. Therefore knowledge about the digestibility of the fat for each animal category, the metabolisible energy content and the efficiency with which this energy can be used for different production goals are of paramount importance for evaluating the fat source of choice. This book has summarized the presently available knowledge from the scientific literature and concluded with a model to estimate the energy content in practice.”

2015. Nilva Kazue Sakomura, et al, eds. “Modelling is a useful tool for decision making in complex agro-industrial scenarios. The book contains a selection of the papers presented at the International Symposium of Modelling in Pig and Poultry Production 2013, and brings together the best and most recent academic work on modelling in the pig and poultry industries, with a particular emphasis on nutrition. It reviews basic modelling concepts, descriptions and applications of production models and new methods and approaches in modelling.”

2016. Michael R. Bedford et al, eds. “This book provides an invaluable resource for all animal and veterinary scientists designing, analyzing and interpreting results from nutrition and feed experiments in pigs and poultry. The emphasis throughout is on practical aspects of designing nutrition experiments. The book builds on the basics and proceeds to describe the limitations of experiment design involving different ingredients. It then characterizes experimental diets including ingredient selection, composition and the minimum proximate analysis required. The text details measurements and the tools available for understanding diverse data sets, data analysis and the eventual publication of the research. … with eight chapters topics of which includes (chapter 1-8 respectively): general principles of designing a nutrition experiment; most common designs and understanding their limits; practical relevance of test diets; characterization of the experimental diets; measurements of nutrients and nutritive value; designing, conducting and reporting swine and poultry nutrition research; extending the value of the literature: data requirements for Holo-analysis and interpretation of the outputs; and presentation and publication of your data.”

2019. Wouter H. Hendricks et al, eds. This book “focuses on the important challenges animal production faces in the light of increasing global feed scarcity, climate change and improvements in animal welfare. Animal nutrition plays a critical role in providing answers to these 21st century challenges. … Among the topics discussed are the use of microbes for natural solutions, the importance of individual feed intake determination, technological treatments of feed ingredients, and advances in modelling. In addition, authors provide their insights on the effects of environment/housing on animal functioning and the impact of climate change on the mycotoxin content of feed ingredients as well as the importance of pro- and antioxidant balance in animals. The increasing global demand for feed will increase the search for alternative feed ingredients especially new protein sources while for an environmentally sustainable human diet, life cycle assessment needs to be combined with other modelling techniques that address environmental impacts of dietary choices at the (inter)national level.”

2019. G Gonzalez-Ortiz et al, eds. “Dietary fibre has been associated with impaired nutrient utilisation and reduced animal performance. A minimum amount of dietary fibre is required to maintain normal physiological functions in the gastrointestinal tract. This book reviews the latest advances in the understanding of dietary fibre for animal nutrition. Fibre clearly has more value than was once thought. This book attempts to define not only the analytical constraints but also the advances in understanding its role in intestinal development and health in both swine and poultry. It identifies how we can exploit fibre to the advantage of the host. Stimulating the gastrointestinal microbiota (often referred to as the second brain) to digest more fibre creates a more favourable environment for intestinal health. This outcome is especially important in antibiotic free diets. The type of fibre employed, the use of exogenous enzymes and the interaction between them, the gastrointestinal microbiota and the host will be covered in detail throughout the chapters.”

2022 (5th ed.) Neville Suttle. “ … this important book reviews recent advances in livestock mineral nutrition, updated throughout with new references that reflect the growing complexity of mineral metabolism. Major related themes covered include the assessment of the 'mineral value' of feeds, the false hopes placed on organic mineral supplements and limiting the 'mineral footprint' of livestock production to lower environmental pollution. Also discussed are new developments and concepts including: Salt tolerance and optimizing production in salt-rich environments; use of phytase rather than phosphate supplements in pig and poultry rations; demineralization of the skeleton during confinement.” The 6th chapter is focused on Phosphorus.

2016. Clive J.C. Philips, ed. “This book explores the importance of good nutrition in ensuring an adequate standard of welfare for farm animals. It is often not realized that farm animals can suffer when they are fed unsuitable diets, which may be because these diets are more economic or the farmer does not know how to rectify poor nutrition. This book reveals how to recognize and deal with feeding problems in farm animals, when the animal's behaviour is indicating a deficiency, through oral stereotypies for example. Feeding livestock in emergency situations can present special challenges, and the availability of clean and potable water, one of the essential components of life, can also be an unrecognized problem for many farm animals. Feeding farm animals effectively is rarely recognized for the major welfare issue that it is. We may assume that animals in intensive husbandry conditions have adequate feed, yet it is often too concentrated and designed primarily to immediately maximize production from the animals, in the form of growth, milk yield or reproduction. In extensive rangeland conditions adequate feed supply also cannot be assured, potentially leading to undernutrition with serious consequences for the health and even survival of livestock.”

2019. Philip I.Hynd. "Nutrition is the key driver of animal health, welfare and production. In agriculture, nutrition is crucial to meet increasing global demands for animal protein and consumer demands for cheaper meat, milk and eggs and higher standards of animal welfare. For companion animals, good nutrition is essential for quality and length of life. Animal Nutrition examines the science behind the nutrition and feeding of the major domesticated animal species: sheep, beef cattle, dairy cattle, deer, goats, pigs, poultry, camelids, horses, dogs and cats. It includes introductory chapters on digestion and feeding standards, followed by chapters on each animal, containing information on digestive anatomy and physiology, evidence-based nutrition and feeding requirements, and common nutritional and metabolic diseases."

2018. Guoyao Wu. This book “consists of 13 chapters. Recent advances in biochemistry, physiology and anatomy provide the foundation to understand how nutrients are utilized by ruminants and non-ruminants. The text begins with an overview of the physiological and biochemical bases of animal nutrition, followed by a detailed description of chemical properties of carbohydrates, lipids, protein, and amino acids. It advances to the coverage of the digestion, absorption, transport, and metabolism of macronutrients, energy, vitamins, and minerals in animals. To integrate the basic knowledge of nutrition with practical animal feeding, the book continues with discussion on nutritional requirements of animals for maintenance and production, as well as the regulation of food intake by animals. Finally, the book closes with feed additives, including those used to enhance animal growth and survival, improve feed efficiency for protein production, and replace feed antibiotics.”
